Graphene-sulfur composite as stable high energy capacity cathodes for Li-ion batteries

Green Car Congress

Yi Cui and Hongjie Dai report the synthesis of a graphene–wrapped sulfur composite material that shows high and stable specific capacities of up to 600 mAh/g over more than 100 cycles. These problems cause poor cycle life, low specific capacity, and low energy efficiency. Nano Letters Article ASAP doi: /10.1021/nl200658.
