Shacklette, L W

Secondary batteries with conjugated polymer anodes, such as polyacetylene, contain an electrolyte including a salt of the formula MB/sub 4//sub -/ /SUB w/ /sub -/ /SUB y/ /sub -/ /SUB z/ R' /SUB w/ R'' /SUB y/ X /SUB z/ wherein M is an alkali metal, B is boron, R is alkyl, R' is aryl or alkyl-substituted aryl, R'' is heterocycle, X is F, Cl, Br, I, CN, OCN, SCN, fluoroaryl or perfluoroalkyl-substituted aryl, w and y are integers of 0 to 4, and z is an integer of 0 to 4, provided that when X is solely F, Cl, I, Br, CN, OCN, SCN or perfluororalkyl, Z is not 4; with the sum x+y+z being equal to or less than 4. Exemplary salts are LiBMe/sub 4/, LiBMe/sub 2/Ph/sub 2/, LiBMe/sub 2/PhPy, LiBMe/sub 2/P /SUB y/ 2 and KBPh/sub 3/SCN (where M=methyl, Ph=phenyl and Py=pyrrolyl). Cathodes such as conjugated backbone polymers (e.g. polyacetylene) and transition-metal chalcogenides (e.g. TiS/sub 2/) are disclosed. The battery can be charged to a state wherein the anode is in a reduced state of 0.1 V-0.5 V (relative to M/M+) where a voltage plateau exists in some instances.
