A polymer containing a recurring unit of anconjugated N-fluoropyridinium salt and an active materialnfor a positive electrode, an electrolyte, a batterynmaterial for the positive electrode and a battery whichnuse such a polymer. That polymer provides a batterynmaterial and a primary battery or a secondary batterynwhich have high electromotive force, high energy density,nhigh environmental acceptibility, a low internalnresistance in charging and discharging and strongnrecoverability of the electromotive force, and can benuseful as a fluorinating agent. |
