摘要
锂硫电池(LSBs)凭借其超高的能量密度,价格低廉,环境友好等优势,有望成为下一代高性能电化学储能器件.然而,目前锂硫电池在商业化应用的道路上还存在着许多挑战,例如硫正极材料导电性能差,多硫化物的穿梭效应以及充放电过程电池内部的体积膨胀等,均是限制锂硫电池实际应用的重要因素.文章总结了近年来锂硫电池正极材料的研究进展,包括碳/硫复合材料、负载金属的碳/硫复合材料以及导电聚合物/硫复合材料.最后,对锂硫电池未来的研究进行了展望.
Abstract
Lithium-sulfur batteries(LSBs)have the potential to be the next generation of high-performance electrochemical energy storage devices due to their ultra-high energy density,low price,and environmental friendliness.However,lithium-sulfur batteries still face many challenges before their commercial application,such as poor conductivity of sulfur-positive electrodes,shuttle effect of polysulfide,and volume expansion of electrodes during charge and discharge.In this study,we demonstrated the recent research progress of cathode materials for lithium-sulfur batteries,including carbon/sulfur composite materials,carbon/sulfur composite materials loaded with metals,and conductive polymer/sulfur composite materials.The future research of lithium-sulfur batteries has prospected at the end.
