Studies of carbon as negative electrode materials for secondary lithium batt≐ries

Abstract A number of carbon materials was investigated as lithium storage anodes. The discharge/ charge characteristics of the carbon anodes and its dependence on solvents were evaluated. The results from this study demonstrated that pyrolytic and carbon coke carbon in a mixed solvent of propylene carbonate (PC) + dimethoxyethane (DME) have high discharge/charge capacity, superior cycling efficiency and good rechargeability, suitable for use as lithium intercalating negatives in lithium ion cells.
