摘要:

本文针对锂硫电池产业化进展缓慢的现状,从实用化层面分析了制约锂硫电池发展的基本问题:正极面容量低,电解液用量高,电池倍率性能差及锂负极的不稳定性,并结合自身工作,提出了解决方案。

关键词: 锂硫电池实用化, 正极面容量, 电解液用量, 电池倍率性能, 锂负极

Abstract:

In view of the slow progress in the industrialization of lithium sulfur batteries, the basic problems restricting the development of lithium sulfur batteries are analyzed from the practical level, W·hich are the low surface capacity of cathode, the high electrolyte ratio, the poor rate performance and the instability of lithium anode. According to their own work, the authors put forward the solution of these problems.

Key words: practicalization of lithium sulfur batteries, surface capacity of cathode, electrolyte ratio, rate performance of lithium sulfur batteries, lithium anode
