Two new organometallic copolymers (PVFVM1 and PVFVM1-1) bearing different molar ratios of ferrocene and triphenylamine pendants were successfully designed and synthesized as cathode active materials for organic-battery applications. Their structural and thermal characteristics were determined by 1H NMR spectroscopy, Fourier transform infrared (FTIR) spectroscopy, size exclusion chromatography (SEC), and thermogravimetric analysis (TGA). Cyclic voltammograms of the as-prepared polymers show that the electrochemical reactions of the ferrocene and triphenylamine moieties are reversible after the first cycle. A composite electrode based on copolymer PVFVM1 exhibits an initial specific discharge capacity of 102 mA h g-1, which corresponds to 98 % of its theoretical capacity (104 mA h g-1). The cycle endurances for both polymers have been evaluated for over 50 cycles. Our results show that both copolymers are good candidates as a new class of cathode active materials and charge-storage materials for rechargeable batteries.
