Novel, high voltage cathode active materials for non-aqueous ammonia based primary and reserve batteries are described therein, as well as non-aqueous electrolytes supporting high voltage, and various anodes, separators and cell constructions are disclosed. Said materials provide higher power output at low temperatures over prior art ammonia based batteries.

High voltage cathode materials for non-aqueous ammonia based

Novel, non-aqueous, high salt concentration ammonia based electrolytes, compatible with lithium based anodes are described therein. Said electrolytes are supporting higher voltage provided by novel cathodes and lithium based anodes, which results in high power density batteries over prior art. Various cathodes, separators and cell constructions are also disclosed.

Non-aqueous ammonia electrolytes for lithium anode based primary and reserve batteries

Non-flammable electrolyte compositions for lithium metal primary batteries and the cells containing these electrolytes are described. The electrolyte compositions comprise one or more partially or fully fluorinated functionalized short chain polyethers with one or more lithium salts, and may include one or more cosolvents, and may have one or more fire retardants added. Said short chain functionalized fluorinated polyethers have much better ionic conductivity than the alkyl terminated fluorinated polyethers or long chain perfluoropolyethers, which provide superior flame resistance without sacrificing overall battery performance. Heat resistant, non-flammable primary lithium cells are also disclosed.
