锂硫电池正极材料改性的研究进展

Research Progress on Modification of Cathode Materials for Lithium-sulfur Batteries

文章主要描述了化学改性碳质材料在锂硫电池中的应用进展,即利用化学改性在在石墨烯等碳质材料上掺杂一些非金属杂原子,使其作为锂硫电池的正极,通过与多硫化锂的化学键合作用,更高效的防止正极活性材料流失,抑制中间态物种LixSy的溶解和扩散。并总结了目前化学改性碳材料在锂硫电池中的研究进展。

This paper mainly describes the application of chemically modified carbonaceous materials in lithium-sulfur batteries.It uses chemical modification to dope non-metallic heteroatoms on carbonaceous materials such as graphene to make them as lithium-sulfur batteries.The positive electrode,by chemical bonding with lithium polysulfide,more effectively prevents the loss of the positive active material and inhibits the dissolution and diffusion of the intermediate species LixSy.The research progress of chemically modified carbon materials in lithium-sulfur batteries is summarized.
