DETAILED DESCRIPTION
[0038] The present invention generally provides a process system with power jet modules coupled to a dispersion chamber and method thereof. The process system includes an array of one or more jet modules, a dispersion chamber, and a reaction chamber. The process system is useful in performing a continuous process to manufacture a particulate material, save material manufacturing time and energy, and solve the problems of high manufacturing cost, low yield, poor quality consistency, low electrode density, low energy density as seen in conventional active material manufacturing processes.
[0039] In one aspect, a liquid mixture, which can be a metal-containing liquid mixture, is promptly jetted into streams of droplets by power jets of the power jet modules and then dispersed into the dispersion chamber. The streams of droplets are continuously mixed with a gas to form a gas-liquid mixture which is then delivered into and reacted in a reaction chamber. Alternatively, the streams of droplets are delivered into and reacted in a reaction chamber.
[0040] In another aspect, a flow of air or gas is served as a gas source for forming a gas-liquid mixture with the liquid mixture, and as a carrying gas for delivering the gas-liquid mixture from the dispersion chamber to the reaction chamber. The gas can also serve as energy source for the gas-liquid mixture to react in the reaction chamber, if such gas is heated before entering into the dispersion chamber.
[0041] Reaction products from the reaction chamber are delivered out of the reaction chamber. The reaction products usually contain solid material particles or fine powers of an oxidized form of the liquid mixture composition (e.g., a metal oxide material, such as fine powers of a mixed metal oxide material), with desired crystal structure, particle size, and morphology. Accordingly, high quality and consistent active particulate materials can be obtained with much less time, labor, and supervision than materials prepared from conventional manufacturing processes.

[0044] The processing system 100 includes a system inlet 102 for delivering the one or more gases into the processing system, a buffer chamber 230 connected to the system inlet 102, dispersion chamber 220 connected to the buffer chamber 230, a reaction chamber 210 connected to the dispersion chamber 220, and a system outlet 104 connected to the reaction chamber 210. In one embodiment, the processing system 100 further includes an array of one or more power jet modules 240A, 240B, 240C, 240D, etc., for jetting the liquid mixture into one or more streams of droplets and to force the one or more streams of droplets into the processing system 100. The processing system further includes a reaction chamber for processing the one or more streams of droplets and the one or more gases into the particulate material.
[0045] The liquid mixture is prepared from two or more precursor compounds and then converted into droplets, each droplet will have the two or more precursors uniformly distributed together. Then, the moisture of the liquid mixture is removed by passing the droplets through the dispersion chamber 220 and the flow of the gas is used to carry the mist within the dispersion chamber for a suitable residence time. It is further contemplated that the concentrations of the precursor compounds in a liquid mixture and the droplet sizes of the mist of the liquid mixture can be adjusted to control the chemical composition, particle sizes, and size distribution of final product particles of the battery material.
[0046] In another embodiment, the processing system 100 further includes, as illustrated by
[0047] In a further embodiment, the processing system 100 also includes the dispersion chamber 220, and power jet modules 240A, 240B and 240C for preparing precursor liquid mixture into desirable size and delivering the desired precursor liquid mixture into the processing system. The power jet modules can be attached to a portion of the dispersion chamber to and employ air pressure to jet the liquid mixture and convert it into a mist containing small sized droplets directly inside the dispersion chamber. Alternatively, a mist can be generated outside the dispersion chamber and delivered into the dispersion chamber. Suitable droplet sizes can be adjusted according to the choice of the power jet module used, the liquid mixture compounds, the temperature of the dispersion chamber, the flow rate of the gas, and the residence time inside the dispersion chamber. As an example, a mist with liquid droplet sizes between one tenth of a micron and one millimeter is generated inside the dispersion chamber.
[0048] In one example, the power jet module 240A is coupled to a portion of the dispersion chamber 220 to generate a mist (e.g., a large collection of small size droplets) of the liquid mixture directly within the dispersion chamber. In general, the power jet module 240A is able to generate a mist of mono-sized droplets. In one embodiment, the dispersion chamber 220 is connected to the one or more power jet modules 240A, 240B and 240C, for receiving multiple uniform gas flows from the buffer chamber and dispersing the multiple uniform gas flows with one or more streams of droplets jetted from the array of one or more power jet modules 240A, 240B and 240C into each other.
[0049] In another example, the dispersion chamber 220 then connects to the reaction chamber 210 for processing the one or more streams of droplets and the one or more gases into the particulate material. Further, the reaction chamber 210 connects to the system outlet 104 for delivering the particulate material out of the processing system.
[0050]
[0051] In one embodiment, the one or more gases F.sub.1 delivered into the buffer chamber 230 is pressured downward to flow at a certain speed through channels 234 of the gas distributor 232 into multiple uniform gas flows F2 out of the channels 234 and into the dispersion chamber 220. In one embodiment, the one or more gases F.sub.1 may be pumped through an air filter to remove any particles, droplets, or contaminants, and the flow rate of the gas can be adjusted by a valve or other means. In one embodiment, the flow rate of multiple uniform gas flows F.sub.2 coming out of the channels 234 will be higher than the flow rate of one or more gases F.sub.1. Additionally, the direction of multiple uniform gas flows F.sub.2 will be gathered and unified.
[0052] In one embodiment, the power jet module 240A include a power jet 242A for jetting a liquid mixture supplied to the power jet module 240A into one or more streams of droplets. The power jet module 240A further includes a support frame 244A for supporting the power jet module 240A, a module actuator 246A attached to the inner side of the support frame 244A for actuating and forcing the one or more streams of droplets F.sub.A jetted from the power jets 242A attached to the inner side of the support frame 244A into the dispersion chamber 220, and a connector 245A connecting the module actuator 246A and power jet 242A. Additionally, the power jet module 240B include a power jet 242B for jetting a liquid mixture supplied to the power jet module 240B into one or more streams of droplets. The power jet module 2408 further includes a support frame 244B for supporting the power jet module 240B, a module actuator 246B attached to the inner side of the support frame 244B for actuating and forcing the one or more streams of droplets FB jetted from the power jets 242B attached to the inner side of the support frame 244B into the dispersion chamber 220, and a connector 245B connecting the module actuator 2468 and power jet 2428.
[0053] In one embodiment, the streams of droplets F.sub.A jetted into the dispersion chamber 220 are dispersed with multiple uniform gas flows F2 in a dispersion angle α.sub.A with each other and forming a gas-liquid mixture F.sub.3 containing the multiple uniform gas flows F.sub.2 and the streams of droplets F.sub.A. Further, the streams of droplets F.sub.B jetted into the dispersion chamber 220 are dispersed with multiple uniform gas flows F2 in a dispersion angle α.sub.B with each other and forming a gas-liquid mixture F.sub.3 containing the multiple uniform gas flows F.sub.2 and the streams of droplets F.sub.B. In one embodiment, the dispersion chamber maintained itself at a first temperate.
[0054] In another embodiment, the one or more gases is heated to a drying temperature to mix with the streams of droplets and remove moisture from the streams of droplets. It is designed to obtain spherical solid particles from a thoroughly-mixed liquid mixture of two or more liquid mixture after drying the mist of the liquid mixture. In contrast, conventional solid-state manufacturing processes involve mixing or milling a solid mixture of liquid mixture compounds, resulting in uneven mixing of liquid mixtures.
[0055] The one or more gas may be, for example, air, oxygen, carbon dioxide, nitrogen gas, hydrogen gas, inert gas, noble gas, and combinations thereof, among others. For example, heated air can be used as an inexpensive gas source and energy source for drying the streams of droplets. The choice of the one or more gas may be a gas that mix well with the streams of droplets of the precursors and dry the mist without reacting to the precursors. In some cases, the chemicals in the streams of droplets may react to the one or more gases and/or to each other to certain extent during drying, depending on the drying temperature and the chemical composition of the precursors. In addition, the residence time of the streams of droplets of thoroughly mixed precursor compounds within the dispersion chamber is adjustable and may be, for example, between one second and one hour, depending on the flow rate of the one or more gas, and the length of the path that the streams of droplets has to flow dispersion within the dispersion chamber.
[0056] In one embodiment, the processing system 100 further includes the reaction chamber 210 for receiving the gas-liquid mixture F.sub.3 and performing a desired reaction of the gas-liquid mixture F.sub.3. into a final reaction product F.sub.4 at a second temperature and for a duration of a reaction time. Lastly, the final reaction products F4, which can be product particles, can be delivered out of the system 100 through system outlet 104 for further analysis on their properties (e.g., specific capacity, power performance, particulate charging cycle performance, etc.), particle sizes, morphology, crystal structure, etc., to be used as a particulate material.
[0057] Optionally, in one embodiment, the reaction chamber 210 is a circulating-type fluidized bed reactor for receiving the gas-liquid mixture F.sub.3 from the dispersion chamber and mixing it with a flow of pre-heated second gas to form a final reaction product F.sub.4 within the internal volume of the reaction chamber 210. The final reaction product F.sub.4 is heated by the thermal energy of the preheated second gas and complete reaction is enhanced by continuously flowing the final reaction product F.sub.4 out of the reaction chamber 210 into a gas-solid separator coupled to the reaction chamber 210. The gas-solid separator is provided to remove side products (and/or a portion of reaction products) out of the system 100 via a separator outlet and recirculating solid particles back into the reaction chamber 210 via a separator outlet. Product particles with desired sizes, crystal structures, and morphology are collected and delivered out of the gas-solid separator via a separator outlet.
[0058] Optionally, in another embodiment, the reaction chamber 210 is a bubbling-type fluidized bed reactor. A flow of pre-heated second gas from the gas line is delivered into the reaction chamber 210 and passes through a porous medium to mix with the gas-liquid mixture F.sub.3 delivered from the dispersion chamber 220 and generate a bubbling gaseous fluid-solid mixture within the internal volume of the reaction chamber. The bubbling gas-solid mixture is heated by the thermal energy of the preheated second gas and complete reaction is enhanced by bubbling flows within the reaction chamber 210. Upon complete reaction, gaseous side products are removed out of the reaction chamber 210 via a reactor outlet. Final reaction product F.sub.4 with desired crystal structures, morphology, and sizes are collected and delivered out of the reaction chamber 210 via the system outlet 104.

A flow of pre-heated second gas from the gas line is delivered into the reaction chamber 210 and also diverted into additional gas flows, such as gas flows, to encourage thorough-mixing of the heated gas with the gas-liquid mixture F.sub.3 delivered from the dispersion chamber 220 and generate a uniformly mixed gas-solid mixture within the internal volume of the reactor reaction chamber. Upon complete reaction, gaseous side products are removed out of the reaction chamber 210 via the reactor outlet. Product particles with desired crystal structures, morphology, and sizes are collected and delivered out of the reaction chamber 210 via the system outlet 104.
[0060] Optionally, in another embodiment, the reaction chamber 210 is a flash-type fluidized bed reactor. The reaction chamber 210 receives the gas-liquid mixture F.sub.3 from the dispersion chamber 220 and mixes it with a flow of pre-heated gas from the gas line to form a gas-solid mixture. The gas-solid mixture is passed through a tube reactor body which is coupled to the reaction chamber 210. The gas-solid mixture has to go through the long internal path, which encourages complete reaction using the thermal energy of the heated gas. Gaseous side products are then removed out of the reaction chamber 210 via the reactor outlet, and product particles with desired crystal structures, morphology, and sizes are collected and delivered out of the reaction chamber 210 via the system outlet 104. It is noted that additional gas lines can be used to deliver heating or cooling air or gas into the reaction chamber 210.

[0117] Method to Perform on a System with Power Jet Modules Coupled to a Dispersion Chamber for Producing a Product Material from a Liquid Mixture
[0118]
[0119] Step 810 of the method 800 includes moving one or more power jet modules in a first direction to be one a jetting position. Step 820 of the method 800 includes opening one or more doors on the one or more power jet modules. Step 830 of the method 800 includes jetting a liquid mixture into one or more streams of droplets into the dispersion chamber by one or more power jets of the one or more power jet modules.
[0120] In one embodiment, the liquid mixture is formed from two or more precursors. In general, liquid form of a precursor compound can be prepared directly into a liquid mixture in a desired concentration. Solid form of a precursor compound can be dissolved or dispersed in a suitable solvent (e.g., water, alcohol, isopropanol, or any other organic or inorganic solvents, and their combinations) to form into a liquid mixture of an aqueous solution, slurry, gel, aerosol or any other suitable liquid forms. For example, desirable molar ratio of two or more solid precursors can be prepared into a liquid mixture, such as by measuring and preparing appropriate amounts of the two or more solid precursors into a container with suitable amounts of a solvent. Depending on the solubility of the precursors in the solvent, pH, temperature, and mechanical stirring and mixing can be adjusted to obtain a liquid mixture where the precursor compounds are fully dissolved and/or evenly dispersed.
[0121] In one example, two or more metal-containing precursors are mixed into a liquid mixture for obtaining a final reaction product of a mixed metal oxide material. Exemplary metal-containing precursors include, but are not limited to, metal salts, lithium-containing compound, cobalt-containing compound, manganese-containing compound, nickel-containing compound, lithium sulfate (Li.sub.2SO.sub.4), lithium nitrate (LiNO.sub.3), lithium carbonate (Li.sub.2CO.sub.3), lithium acetate (LiCH.sub.2COO), lithium hydroxide (LiOH), lithium formate (LiCHO.sub.2), lithium chloride (LiCl), cobalt sulfate (CoSO.sub.4), cobalt nitrate (Co(NO.sub.3).sub.2), cobalt carbonate (CoCO.sub.3), cobalt acetate (Co(CH.sub.2COO).sub.2), cobalt hydroxide (Co(OH).sub.2), cobalt formate (Co(CHO.sub.2).sub.2), cobalt chloride (CoCl.sub.2), manganese sulfate (MnSO.sub.4), manganese nitrate (Mn(NO.sub.3).sub.2), manganese carbonate (MnCO.sub.3), manganese acetate (Mn(CH.sub.2COO).sub.2), manganese hydroxide (Mn(OH).sub.2), manganese formate (Mn(CHO.sub.2).sub.2), manganese chloride (MnCl.sub.2), nickel sulfate (NiSO.sub.4), nickel nitrate (Ni(NO.sub.3).sub.2), nickel carbonate (NiCO.sub.3), nickel acetate (NRCH.sub.2COO).sub.2), nickel hydroxide (Ni(OH).sub.2), nickel formate (Ni(CHO.sub.2).sub.2), nickel chloride (NiCl.sub.2), aluminum (Al)-containing compound, titanium (Ti)-containing compound, sodium (Na)-containing compound, potassium (K)-containing compound, rubidium (Rb)-containing compound, vanadium (V)-containing compound, cesium (Cs)-containing compound, chromium (Cr)-containing compound, copper (Cu)-containing compound, magnesium (Mg)-containing compound, iron (Fe)-containing compound, and combinations thereof, among others.
[0122] Not wishing to be bound by theory, it is contemplated that, in order to prepare an oxide material with two or more different metals, all of the required metal elements are first mixed into a liquid mixture (e.g., into a solution, a slurry, or a gel mixture) using two or more metal-containing precursor compounds as the sources of each metal element such that the two or more different metals can be mixed uniformly at desired ratio. As an example, to prepare a liquid mixture of an aqueous solution, slurry, or gel, one or more metal salts with high water solubility can be used. For example, metal nitrate, metal sulfate, metal chloride, metal acetate, metal formate can be used. Organic solvents, such as alcohols, isopropanol, etc., can be used to dissolve or disperse metal-containing precursors with low water solubility. In some cases, the pH value of the liquid mixture can be adjusted to increase the solubility of the one or more precursor compounds. Optionally, chemical additives, gelation agents, and surfactants, such as ammonia, EDTA, etc., can be added into the liquid mixture to help dissolve or disperse the precursor compounds in a chosen solvent.
[0123] In one embodiment, the power jet modules are selected from a group of a nozzle, a sprayer, an atomizer, or any other mist generators. The power jet modules employ air pressure to jet the liquid mixture and convert it into liquid droplets. As an example, an atomizer can be attached to a portion of the dispersion chamber to spray or inject the liquid mixture into a mist containing small sized droplets directly inside the dispersion chamber. In general, a mist generator that generates a mist of mono-sized droplets is desirable. Alternatively, a mist can be generated outside the dispersion chamber and delivered into the dispersion chamber.
[0124] Desired liquid droplet sizes can be adjusted by adjusting the sizes of liquid delivery/injection channels within the mist generator. Droplet size ranging from a few nanometers to a few hundreds of micrometers can be generated. Suitable droplet sizes can be adjusted according to the choice of the mist generator used, the liquid mixture compounds, the temperature of the dispersion chamber, the flow rate of the first gas, and the residence time inside the dispersion chamber. As an example, a mist with liquid droplet sizes between one tenth of a micron and one millimeter is generated inside the dispersion chamber.
[0125] Not wishing to be bound by theory, in the method 800 of producing a particulate material, it is contemplated that the two or more precursor compounds are prepared into a liquid mixture and then converted into droplets, each droplet will have the two or more precursors uniformly distributed together. Then, the moisture of the liquid mixture is removed by passing the droplets through the dispersion chamber and the flow of the first gas is used to carry the mist within the dispersion chamber for a suitable residence time. It is further contemplated that the concentrations of the precursor compounds in a liquid mixture and the droplet sizes of the mist of the liquid mixture can be adjusted to control the chemical composition, particle sizes, and size distribution of final product particles of the battery material.
[0126] In one embodiment, the one or more streams of droplets is dispersed into the dispersion chamber at a first temperature and for a desired first residence time to remove its moisture. As the dispersion of the moisture from the one or more streams of droplets of the precursor compounds is performed within the dispersion chamber filled with a gas flow, a gas-liquid mixture composing of the heated first gas and the liquid mixture is formed. Accordingly, one embodiment of the invention provides that the gas flow flowed within the dispersion chamber is used as the gas source for forming a gas-liquid mixture within the dispersion chamber. In another embodiment, the gas flown within the dispersion chamber is heated and the thermal energy of the heated gas flows served as the energy source for carrying out drying reaction and other reactions inside the dispersion chamber. The gas flow can be heated to a temperature of between 70° C. to 600° C. by passing through a suitable heating mechanism, such as electricity powered heater, fuel-burning heater, etc.
[0127] In one configuration, the gas flow is pre-heated prior to flowing into the dispersion chamber. Optionally, drying the one or more streams of droplets can be carried out by heating the dispersion chamber directly, such as heating the chamber body of the dispersion chamber. The advantages of using heated gas are fast heat transfer, high temperature uniformity, and easy to scale up, among others. The dispersion chambers may be any chambers, furnaces with enclosed chamber body, such as a dome type ceramic dispersion chamber, a quartz chamber, a tube chamber, etc. Optionally, the chamber body is made of thermal insulation materials (e.g., ceramics, etc.) to prevent heat loss during drying.
[0128] The gas flow may be, for example, air, oxygen, carbon dioxide, nitrogen gas, hydrogen gas, inert gas, noble gas, and combinations thereof, among others. For example, heated air can be used as an inexpensive gas source and energy source for drying the mist. The choice of the gas flow may be a gas that mix well with the mist of the liquid mixtures and dry the mist without reacting to the liquid mixtures. In some cases, the chemicals in the droplets/mist may react to the gas flow and/or to each other to certain extent during drying within the dispersion chamber, depending on the first temperature and the chemical composition of the liquid mixtures. In addition, the residence time of the mist of thoroughly mixed liquid mixture compounds within the dispersion chamber is adjustable and may be, for example, between one second and one hour, depending on the flow rate of the gas flow, and the length of the path that the mist has to flow through within the dispersion chamber.
[0129] Step 840 of the method 800 includes processing the one or more streams of droplets inside a reaction chamber of the processing system. The reaction chamber can be a fluidized bed reactor, such as a circulating fluidized bed reactor, a bubbling fluidized bed reactor, an annular fluidized bed reactor, a flash fluidized bed reactor, and combinations thereof. In addition, the reaction chamber can be any of a furnace-type reactor, such as a rotary furnace, a stirring furnace, a furnace with multiple temperature zones, and combinations thereof.
[0130] In one embodiment, the one or more streams of droplets is reacted for a second residence time into a reaction product and at a second temperature inside the reaction chamber. The second residence time may be any residence time to carry out a complete reaction of the streams of droplets, such as a residence time of between one second and ten hours, or longer. Reactions of the streams of droplets within the reaction chamber may include any of oxidation, reduction, decomposition, combination reaction, phase-transformation, re-crystallization, single displacement reaction, double displacement reaction, combustion, isomerization, and combinations thereof. For example, the streams of droplets may be oxidized, such as oxidizing the liquid mixture compounds into an oxide material.
[0131] In one embodiment, it is contemplated to obtain a type of solid particles from a reaction of the streams of droplets within the reaction chamber using energy from a second gas flow that is heated to a reaction temperature to fully complete the reaction and obtain desired crystal structure of final reaction products. The advantages of flowing air or gas already heated are faster heat transfer, uniform temperature distribution (especially at high temperature range), and easy to scale up, among others. Exemplary second gas flow include, but are not limited to air, oxygen, carbon dioxide, an oxidizing gas, nitrogen gas, inert gas, noble gas, and combinations thereof. For an oxidation reaction inside the reaction chamber, an oxidizing gas can be used as the second gas flow. For reduction reactions inside the reaction chamber, a reducing gas can be used as the second gas flow.
[0132] In one embodiment, a reaction products (e.g., a gas-solid mixture of oxidized reaction products mixed with second gas and/or other gas-phase by-products, or waste products, etc.) are delivered out of the reaction chamber and cooled to obtain final solid particles of desired size, morphology, and crystal structure, ready to be further used for battery applications. For example, the reaction product may be slowly cooled down to room temperature to avoid interfering or destroying a process of forming into its stable energy state with uniform morphology and desired crystal structure.
[0133] Step 850 of the method 800 includes closing the one or more doors of the power jets modules. Step 860 of the method 800 includes moving the one or more power jet modules in a second direction to be on a park .position. Optionally, Step 810 of the method 800 will be performed after Step 860. Step 870 of the method 800 includes moving one or more power jet modules in a third direction to position the one or more power jet modules to a service position. Optionally, Step 810 of the method 800 will be performed after Step 870.
[0134]
[0135] Step 910 of the method 900 includes moving one or more power jet modules in a first direction to be on a jetting position. Step 920 of the method 900 includes moving one or more power jet modules in a second direction to be on a park position. Step 930 of the method 900 includes moving one or more power jet modules in a third direction to position the one or more power jet modules to a service position. Step 940 of the method 900 includes cleaning the one or more power jets using one or more cleaning assemblies to remove unwanted build-ups materials and contaminants. Optionally, either step 910, 920, or 930 can be performed after step 940 of the method 900.
