摘要： A method for manufacturing thin films for a battery device. The method includes vaporizing a precursor material from a liquid source to form droplets ranging from, for example, about 10 microns to about 20 microns. Thereafter, the method includes subjecting the droplets from about 10 to about 20 microns to a megasonic energy source to cause formation of a plurality of smaller droplets ranging from, for example, about 0.25 micron to about 5 microns which are then directed to a heated substrate, where through a heterogeneous reaction a film of material overlying the surface region is formed. The method includes irradiating (e.g., ultra-violet, infra-red, or plasma) the film of material using electromagnetic radiation to process the film to cause a recrystallization of the film to form larger sized crystalline materials. Optionally, the method includes sequentially performing the vaporizing, reacting/releasing, and irradiating to build up a thickness of the film of material.

摘要： Set forth herein are processes for making lithium-stuffed garnet oxides (e.g., Li7La3Zr2O12, also known as LLZO) that have passivated surfaces comprising a fluorinate and/or an oxyfluorinate species. These surfaces resist the formation of oxides, carbonates, hydroxides, peroxides, and organics that spontaneously form on LLZO surfaces under ambient conditions. Also set forth herein are new materials made by these processes.

摘要： Provided are battery packs and interface modules for electrically interconnecting electrochemical cells in the packs and for providing heat distribution with the packs. An interface module interfaces one side of all electrochemical cells in a battery pack. The interface module may have a substantially planar shape such that the space occupied by the module in the battery pack is minimal. Most, if not all, conductive components of the interface module may be formed from the same sheet of metal. In some embodiments, the interface module includes multiple bus bars such that each bus bar interconnects two or more terminals of different electrochemical cells in the battery pack. Each bus bar may have a separate voltage sense lead extending from the bus bar to a connecting portion. The bus bars may be flexibly supported within the module. The interface module may also include multiple thermistors disposed on different bus bars.
