Abstract

A non-aqueous secondary battery has been constructed by using Zn metal as the anode and chemically synthesised PEDOT as the cathode, with a 1-ethyl-3-methylimidazolium dicyanamide ionic liquid as the electrolyte, which avoids dendritic growth processes on the Zn surface upon charge/discharge cycling. The novel Zn/PEDOT rechargeable cell shows high efficiency and cycling ability, performing over 320 cycles with no indication of short circuit. Both the Zn and PEDOT surfaces showed minimal signs of degradation, suggesting that a Zn/PEDOT electrochemical device would be capable of extended cycle life under numerous charge/discharge cycles.
