Lithium battery

Lithium battery may refer to:

Solution of lithium tetrachloroaluminate in thionyl chloride is the liquid cathode and electrolyte of some lithium batteries, e.g. the lithium-thionyl chloride cell. Another cathode-electrolyte formulation is lithium tetrachloroaluminate + thionyl chloride + sulfur dioxide + bromine.

Other salts used in lithium battery electrolytes are lithium bromide, lithium perchlorate, lithium tetrafluoroborate, and lithium hexafluorophosphate; less-common ones are lithium chloride, lithium iodide, lithium chlorate, lithium nitrate, lithium hexafluoroarsenate, lithium hexafluorosilicate (i.e. lithium and hexafluorosilicic acid), lithium bis(trifluoromethanesulfonyl)imide, and lithium trifluoromethanesulfonate.
