A method for the formation of lithium includes a layer on a substrate using an atomic layer deposition method. The method includes the sequential pulsing of a lithium precursor through a reaction chamber for deposition upon a substrate. Using further oxidizing pulses and or other metal containing precursor pulses, an electrolyte suitable for use in thin film batteries may be manufactured.

An example composition is disclosed. For example, the composition includes a ultra-violet (UV) curable mixture of water, an acid, a phosphine oxide with one or more photoinitiators, a water miscible polymer, a salt, and a neutralizing agent. The composition can be used to form an electrolyte layer that can be cured in the presence of air when printing the thin-film battery.

Provided is room temperature stable δ-phase Bi.sub.2O.sub.3. Ion conductive compositions comprise at least 95 wt % δ-phase Bi.sub.2O.sub.3, and, at 25° C., the compositions are stable and have a conductivity of at least 10.sup.−7 S/cm. Related methods, electrochemical cells, and devices are also disclosed.

Ceramic-polymer film includes a polymer matrix, plasticizers, a lithium salt, and a ceramic nanoparticle, LLZO: Al.sub.xLi.sub.7-xLa.sub.3Zr.sub.1.75Ta.sub.0.25O.sub.12 where x ranges from 0 to 0.85. The nanoparticles have diameters that range from 20 to 2000 nm and the film has an ionic conductivity of greater than 1×10.sup.−4 S/cm (−20° C. to 10° C.) and larger than 1×10.sup.−3 S/cm (≥20° C.). Using a combination of selected plasticizers to tune the ionic transport temperature dependence enables the battery based on the ceramic-polymer film to be operable in a wide temperature window (−40° C. to 90° C.). Large size nanocomposite film (area ≥8 cm×6 cm) can be formed on a substrate and the concentration of LLZO nanoparticles decreases in the direction of the substrate to form a concentration gradient over the thickness of the film. This large size film can be employed as a non-flammable, solid-state electrolyte for lithium electrochemical pouch cell and further assembled into battery packs.

Further described is a method for using an additive manufacturing (AM) process to produce an object constructed of the ionically conductive composition by use of particles of the ionically conductive composition as a feed material in the AM process.

Solid-state batteries, battery components, and related processes for their production are provided. The battery electrodes or separators contain sintered electrochemically active material, inorganic solid particulate electrolyte having large particle size, and low melting point solid inorganic electrolyte which acts as a binder and/or a sintering aid in the electrode.

An alkaline battery is made by press-fitting a plurality of tubular positive electrode pellets inside of an open end of a cylindrical positive electrode can. The press-fitting is performed in such a manner as to stack the positive electrode pellets coaxially inside of and in contact with the positive electrode can, with gaps between adjacent positive electrode pellets. A separator is disposed inside of the tubular pellets, and a negative electrode mixture is placed inside of the separator. A negative electrode current collector is inserted into the negative electrode mixture, and the opening at the open end of the positive electrode can is sealed with a negative electrode terminal plate.
