A nwe conductive polymer,poly-N-methylaniline,used as acathode -active material in rechargeable batteries,is very stable in aqueous solution. The cell, composed of poly-N-methylaniline, Zn and 1. 0 mol/L ZnCl2(pH = 2. 01), hah an open - circuit voltage of 1. 31V. The capacity value and energy density of poly-N-methylaniline are 97. 5Ah/kg and 94. 6 Wh/kg at a constant discharge current of 0. 15 mA/cm2 (discharge voltage 0. 90V, the weight of polymer;35. 6 mg/cm2). The coulombic efficiency of poly-N-methylaniline is 95. 4.% at a constant current rate of 0. 15 mA/cm2.
