PURPOSE:To improve the electrically capacity thus to obtain a small and light nonaqueous cell having excellent cyclic performance and self-discharge characteristic by covering the surface of conductive macromolecules with reaction product between specific cyclic ester and n-doped conductive macromolecules. CONSTITUTION:Cyclic ester shown by formula I n-doped conductive macromolecules are reacted to produce reaction product for covering the surface of conductive macromolecules. Covering method includes chemical doping and electrochemical doping where cyclic ester shown by formula I is generally employed as nonaqueous electrolytic solvent and electrochemical doping is particularly suitable. In the solvent, the content of compound I (wt% excluding the electrolyte) is normally 0.1-100wt%, preferably 10-100wt%. |
