Electrosynthesized dedoped polyaniline (anode) and doped poly-l-naphthol (cathode) were used as electrode materials in a new rechargeable battery containing lithium perchlorate and perchloric acid in methyl cyanide (MeCN) as the electrolyte. Thc cell gave an open-circuit potential (OCP) of 1.4 V, a specific capacity of 150 Ah kg(-1) and an energy density of 113 W h kg(-1) (at a 1.0 V cutoff). The cell lost similar to5% of its capacity after 1. week due to the self-discharge. The charging/discharging tests (0.0-1.4 V) showed a gradual decrease in capacity up to 15% after 100 cycles. An advantage of such battery is the high power density (similar to9 kW kg(-1) at OCP) because of the extended surface area of the polymer layer compared to the metal electrode.
