摘要
介绍了影响锂硫电池实用化的瓶颈问题,如硫利用率低、不可逆Li2S形成、硫正极结构不稳定等;综述了性能改善方案,如硫正极改性、S/C复合、合适的粘结剂、胶体电解质及锂负极保护等;最后提出了今后重点研究的方向。
The bottleneck problems that limit the application of lithium sulfur battery are introduced in detail, such as low sulfur utilization, formation of irreversible Li2S, instability of porous structure of the cathode. Further- more, the programmes for improving performance of Li/S battery are reviewed as follow： modification of sulfur catho- de, composition of sulfur/carbon materials, appropriate binder, colloidal electrolyte and protection of lithium anode. Finally, the prospects of the future research on lithium sulfur batteries are proposed.
