Development of fast charge profiles for lithium-ion batteries
A method of developing a charging profile for charging a lithium-ion battery. A first phase of charging is at a constant current level, with the constant current level selected on the basis of battery resistance during charging and differential voltage (dV/dQ) analysis. A switch point is selected on the basis of a state of charge (SOC) of the battery when dV/DQ values increase. Next is an increasing voltage charging phase, with the voltage rate selected on the basis of charge acceptance and charge time.
System for generating electrical power from flue gas and captured carbon dioxide
A system for collecting flue gas from a combustion process wherein the flue gas has elevated concentrations of carbon dioxide and converting it into electrical power and useful by-products. Kinetic energy of flue gas is used to power a wind turbine that is coupled to a generator to generate electricity. A scrubber isolates CO2 from other components of the flue gas. The CO2 is converted and stored in carbonic acid solution. The carbonic acid solution is then provided to a galvanic cell that generates electrical power and converts the reactant materials in the cell into useful by-products.
Method for assembling and activating lithium-ion based reserve batteries
A method for assembling a lithium-ion reserve battery. The method including: charging an assembled lithium-ion reserve battery, the assembled lithium-ion battery including electrodes forming a battery cell, electrolyte and a membrane separating the battery cell and the electrolyte, the electrodes being charged into a charged state; disassembling the charged lithium-ion reserve battery; rinsing and drying at least the electrodes of the disassembled lithium-ion reserve battery; and reassembling the lithium-ion reserve battery with the rinsed and dried electrodes in the charged state and without the electrolyte; wherein the reassembling includes hermetically sealing a housing containing the battery cell. A method for activating such lithium-ion battery further includes, subsequent to the reassembly, introducing the electrolyte into the battery cell to activate the lithium-ion battery.
BATTERY PACK, AND ELECTRIC APPLIANCE USING BATTERY PACK
In order that the output voltage of a battery pack can be switched and the battery pack can be shared among different voltage electric appliances, this battery pack has a switching mechanism that switches outputting a low voltage by parallel connection of two cell units or outputting a high voltage by series connection of the two cell units, said two cell units each being composed of a plurality of cells connected in series, wherein the switching mechanism is configured from a change-over switch having an operation lever (452). The change-over switch is embedded in a battery pack (400), and an operator is able to manually switch outputting 18 V by setting the operation lever (452) at a first position or outputting 36 V by setting the operation lever (452) at a second position.
Electrode blanks for use in electrochemical devices
Fabricating the electrode blank includes baking a blank precursor. The blank precursor contains the components of an electrode active medium including an active material. Fabricating the electrode blank also includes performing one or more post-bake calender operations on the blank precursor after baking the blank precursor. Each post-bake calender operation includes calendering the blank precursor.
