Title: A new electrode-active material for polymer batteries: Polyvinylferrocene

The electrochemical characteristics of polyvinylferrocene (PVF) was investigated for use as an electrode-active material rechargeable batteries. Charge-discharge curves of the PVF electrodes showed excellent potential flatness and very high coulombic efficiencies in both nonaqueous and aqueous solutions. The dispersion of graphite powder in PVF was very useful for increasing the discharge rate and PVF utilization. The self-discharge rates were found to be as low as 1% in the first day. It is concluded that PVF is a promising material as an electrode-active material in rechargeable batteries.
