Abstract
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.
Claims19
A r.on-aqueous primary battery having ammonia based electrolyte, an alkali metal anode(s), a porous non-conductive separator(s) and a cathode(s), and in which battery the cathode(s) active material contains a persulfate salt, which has a general structure represented by the formula:
- X2S2O8, wherein X is representative of a cation with an ionic charge of 1+(such as Na+, K+, NH4+) with associated anion of S2O82-.
A non-aqueous reserve battery having ammonia based electrolyte, an alkali metal anode(s), a porous non-conductive separator(s) and a cathode(s), and in which battery the cathode active material contains a persulfate salt, which has a general structure represented by the formula:
- X2S2O8, wherein X is representative of a cation with an ionic charge of 1+(such as Na+, K+, NH4+) with associated anion of S2O82-.
