Abstract
A composite carbon anode has been developed for a room temperature polymer electrolyte cell using poly(ethylene oxide) (PEO). By means of half-cells the charge/discharge process has been studied and the specific capacity of the Li x C 6 electrode as a function of cycle number determined. This has been supported by impedance analysis which has been carried out at various electrode compositions. Data on the effect of carbon content on performance and the influence of elevated temperature (40°C) are reported. Good cycleability of a polymer electrolyte cell comprising a carbon anode, PEO-based electrolyte and a high voltage intercalating cathode LiMn 2O 4 has been demonstrated.
