DIMMER, TRIMMER, OR POLYMER CONTAINING CONJUGATED N-FLUOROPYRIDINIUM SALT Russian patent published in 2002 - IPC

FIELD: chemical power sources. SUBSTANCE: dimmer, trimmer, or polymer containing conjugated N-fluoropyridinium salt and having number-average molecular weight above 500000 is prepared by bringing dimmer, trimmer, or polymer into reaction with fluorine in solvent mixture in presence of Broensted acid or its salt. Polymer is transformed into positive active material - electrolyte used as positive electrode of accumulator battery. Polymer find also use as fluorination agent. EFFECT: increased electromotive force, energy density, and environmental appropriateness, and also reduced internal resistance during charging and discharging ensuring high ability to restore electromotive force. 17 cl, 9 dwg, 5 tbl
