Abstract

In this work, a new cathode material for lithium–sulfur (Li–S) batteries was developed. Microporous carbon (with predominant pore size £1.2 nm) served as both a matrix for sulfur retention and conductive additive. Microporous carbon was shown to be capable of adsorbing lithium polysulfides thereby suppressing their migration toward lithium anode. The discharge capacity of the S/C composite at the 1st and 20th cycles in Li–S battery operation was 513 and 421 mAh g–1 at a scan rate of 0.1 mV s–1.

基于硫和微孔碳的锂-S 电池复合阴极材料

在这项工作中，开发了一种用于锂硫（Li-S）电池的新型阴极材料。微孔碳（主要孔径为 1.2 nm 英镑）既是硫的保留基质，又是导电添加剂。研究表明，微孔碳能够吸附多硫化锂，从而抑制其向锂阳极迁移。在 0.1 mV s-1 的扫描速率下，S/C 复合材料在锂-S 电池运行的第 1 次和第 20 次循环中的放电容量分别为 513 mAh g-1 和 421 mAh g-1。

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
