    • Secondary batteries with conjugated polymer anodes, such as polyacetylene, contain an electrolyte including a salt of the formula MB.sub.4-w-y-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.sup.+) where a voltage plateau exists in some instances.
    • 具有共轭聚合物阳极的二次电池,例如聚乙炔,含有包含式MB4-wy-zR'wR''yXz的盐的电解质,其中M是碱金属,B是硼,R是烷基,R'是芳基或 烷基取代的芳基,R“是杂环,X是F,Cl,Br,I,CN,OCN,SCN,氟代芳基或全氟烷基取代的芳基,w和y是0-4的整数,z是 0至4,条件是当X仅为F,Cl,I,Br,CN,OCN,SCN或全氟烷基时,Z不为4; x + y + z的和x等于或小于4.示例性的盐是LiBMe4,LiBMe2Ph2,LiBMe2PhPy,LiBMe2Py2和KBPh3SCN(其中M =甲基,Ph =苯基和Py =吡咯基)。 公开了诸如共轭主链聚合物(例如聚乙炔)和过渡金属硫族化物(例如TiS 2)的阴极。 可以将电池充电到在某些情况下存在电压平台的情况下,阳极为0.1V-0.5V(相对于M / M +)的还原状态。
