A polymer having repeating units of a conjugated N-fluoropyridinium salt, and a positive active material, electrolyte, positive electrode battery material and battery each prepared from the polymer. The battery material and primary and secondary batteries have high electromotive force, energy density and environmental affinity, are reduced in the internal resistance during charge and discharge, and a strong recovery of the electromotive force. The polymer is also useful as a fluorinating agent. |
