Two tin-graphite composite electrodes were evaluated for their use as high capacity anodes in recahargeable lithium ion cells. The initial charge capacitie of these two electrodes were 520 mAh/g, respectively. Cyclic voltammetry and charge-discharge cycling studies point to the alloy formation reaction between tin and lithium being the main contributing factor ot the increased capacity. The capacity ofthese electrodes decreases with cycling but maintains considerably higher capacity than graphite electrode with same number of cycles. The development of optimized tin-graphite composite electrodes with much higher capacity than graphite electrodes looks promising.
