Performance Study of Zn / ZnCl2, NH 4Cl / Polyaniline / Carbon Battery

A secondary battery of the type , carbon is described. The polymer was electrodeposited on porous carbon rods, in the form of consistent, rather thick, highly porous, and low‐resistance layers. The battery was assembled in a configuration similar to that of the classical R‐6 dry cell. The performance of the battery has been studied, and it shows characteristics comparable to those of conventional systems: moderate specific energy (50–100 Wh · kg −1 ), very good coulombic efficiency (70–100%), low self‐discharge rate (<1% day), and excellent cyclability at high current densities.
