Abstract
A battery having electrodes, at least one of which is made of a polymeric compound having conjugated double bonds in the main chain, is described. The organic solvent of an electrolytic solution in the battery is selected from nitrile compounds of the formulae (I) and (II): EQU R--CN (I) wherein R is a C2-7 alkyl, a saturated alicyclic C3-7 hydrocarbon residue, CH.sub.3 --(CH.sub.2).sub.x --O--(CH.sub.2).sub.y or NC--CH.sub.2).sub.z (x, y and z are 0 or a positive integer of up to 5), and ##STR1## wherein R.sub.1 is --(CH.sub.2).sub.p --CN, --O--(CH.sub.2).sub.q --CN or ##STR2## in which R.sub.3 is a C1-5 alkyl and p, q and r are 0 or a positive integer of up to 5, R.sub.2 is C1-5 alkyl, C1-5 alkoxy or --CH.sub.2).sub.l --CN in which l is 0 or a positive integer of up to 3, and m is a positive integer of up to 3, and n is 0 or a positive integer of up to 3.
