Abstract
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.
Claims11
A non-aqueous reserve battery having ammonia based electrolyte with an electrolyte salt concentration at least 21% by weight, a lithium metal based anode, a porous electrically non-conductive separator and a cathode, which cathode's active materials are selected from the group including persulfate salt, molybdenum oxide, a permanganate, meta-dinitrobenzene and mixtures thereof.
A non-aqueous ammonia based electrolyte for lithium metal anode based reserve batteries, comprising non-aqueous ammonia NH3 with at least one salt selected from the group including LiBF4, LiPF6, LiTFSI, LiSCN, NH4SCN, KSCN and LiNO3 dissolved therein, having salt concentration of at least 46% by weight.
