A rechargeable battery of the type Zn/ZnCl2, NH4CL/polvaniline (PAn)-reticulated vitreous carbon was successfully prepared based on a PAn modified electrode. Voltage of the battery was 1.2 V. Charge-discharge behavior at a constant load of 2.5 kOmega, recycle ability and the rate of self-discharge were measured. The results showed that the battery has a capacity of 121 mAhg(-1) polymer weight and coulombic efficiency was in the range between 75% and 100%. Selfdischarge rate was less than 1%. per day and the battery showed a good recycle ability. It was also found that even after 70 cycles, the decrease in the open-circuit voltage was less than 5%.
