摘要

由于硫(硒)的导电性差、多硫(硒)化物的溶解、硫(硒)的体积膨胀、锂枝晶等问题,导致构建稳定的界面成为锂硫(硒)电池面临的重大挑战. 本文介绍了锂硫(硒)电池的研究进展,并以本课题组的研究工作为主,着重讨论了纳米限域效应、化学成键、界面吸附、表面包覆、电解液优化、负极改进等技术方案在锂硫(硒)电池中构建稳定界面的可行性.

Abstract

The stable interface is still a challenge for lithium-sulfur (selenium) batteries because of the low conductivity of sulfur (selenium), dissolution of polysulfide (polyselenide), volume expansion of sulfur (selenium), and lithium dendrite growth. This review describers some recent developments in lithium-sulfur (selenium) batteries and highlights our efforts in this field. The possible strategies for building stable interface in the lithium-sulfur (selenium) batteries including nano-restriction effect, chemical bonding, interface adsorption, surface coating, electrolyte optimization, and Lithium anode treatment have been discussed.
