固态锂金属电池安全性研究进展

Research Progress on Safety of Solid-State Lithium Metal Batteries

目前,固态锂金属电池(SSLMB)是实现高能量密度的下一代储能设备之一,其中,全固态电解质(SSEs)的使用有望彻底解决锂金属负极带来的安全问题。由于以往对SSEs电池的刻板印象,大部分研究主要集中于提高SSLMBs的电化学性能,而忽略了其安全性问题。然而,在实际研究过程中,SSLMBs潜在安全性问题逐渐暴露。本综述总结了几种可能引发电池安全问题的原因,并简要概述了相应解决方案。最后,对今后超高安全性SSLMBs的研究进行了总结和展望。

Nowadays, the solid-state lithium metal battery (SSLMB) has been one of the next-generation energy storage devices that is expected to achieve high energy density. The use of solid-state electrolytes (SSEs) is expected to completely solve the safety problems caused by lithium metal anode. Due to the stereotype of SSEs were always safe in the past, most of the previous studies focused on improving the electrochemical performance of SSLMBs, but ignored the safety issues. However, the potential security problems of SSLMBs are gradually exposed in practical research. This review summarizes several possible causes of battery safety problems and provides a brief overview of corresponding solutions. Finally, the perspectives on ultra-high safety SSLMBs are also summarized and prospected.
