摘要
Abstract
Graphene was used as a sulfur carrier to synthesize G/S composite via the ball milling-melting method.Then,as a contrast sample,the composite was modified by metal oxide,and the state of the graphene sulfur materials and the modified composite were all characterized.We tested the performances of the sample battery.The results showed that the specific capacity of the composite be-fore modification was 1 141 mAh/g,and after modification it was 1 256 mAh/g,the specific capacity was increased by 10.08％after modification,and the cycle performance is also significantly improved.关键词
