Preparation and electrochemical characteristics of a new rechargeable Li/PAn[FeOCl(an)] cell

To increase the rechargeability and energy density, polyaniline(PAn)/FeOCl(an) composite cathode was made newly. The electrochemical characteristics of its lithium cells at 30°C were investigated by using cyclic voltammetry, a.c. impedance method, and other techniques. Especially, the reducing and enhancement effects of the resistance at electrolyte/cathode interface and the energy density by using the conducting polyaniline thin film could be plausibly explained.
