金属氧化物/炭复合材料抑制锂硫电池穿梭效应的研究进展
A review of the use of metal oxide/carbon composite materials to inhibit the shuttle effect in lithium-sulfur batteries
摘要
Abstract
Lithium-sulfur(Li-S)batteries are among the most promising next-generation electrochemical energy-storage systems due to their exceptional theoretical specific capacity,inexpensive production cost and environmental friendliness.However,the poor conductivity of S and Li2S,severe lithium polysulfide(LiPS)shuttling and the sluggish redox kinetics of the phase transformation greatly hinder their commercialization.Carbonaceous materials could be potentially useful in Li-S batteries to tackle these problems with their high specific surface area to host LiPSs and sulfur and excellent electrical conductivity to increase electron transfer rate.However,non-polar carbon materials are unable to interact closely with the highly polar polysulfides,resulting in a low sulfur utiliza-tion and a serious shuttle effect.Because of their advantages of strong polarity and a large number of adsorption sites,integrating transition metal oxides(TMOs)with carbon-based materials(CMs)increases the chemical adsorption of LiPSs and electrochemical reaction activity for LiPSs.The working principles and main challenges of Li-S batteries are discussed followed by a review of re-cent research on the ex-situ and in-situ synthesis of TMO/CM composites.The formation of TMO/CMs with the dimensionalities of CMs from 1D to 3D are then reviewed together with ways of changing their structure,including heterostructure design,vacancy en-gineering and facet manipulation.Finally,the outlook for using TMO/CMs in Li-S batteries is considered.关键词
