Abstract:

All-solid-state lithium batteries (ASSLBs) exhibit higher energy density and more safety than current liquid lithium batteries, which are the main research direction for next-generation energy storage devices. Compared with other solid-state electrolytes, sulfide solid-state electrolytes (SSEs) have the characteristics of ultra-high ionic conductivity, low hardness, easy processing, and good interfacial contact, which are one of the most promising routes to realize all-solid-state batteries. However, there are some interfacial issues between anodes and SSEs that limit their applications such as interfacial side reactions, poor rigid contact, and lithium dendrite. This study outlines the current progress in anode materials used for sulfide-based ASSLBs, summarizes the development status, application advantages, interface problems and mainstream solution strategies of the main anode materials including lithium metal, lithium alloys, silicon anode for sulfide-based ASSLBs, and provides guiding suggestions for the next development of anode materials and the solution of interfacial issues.

Key words: all-solid-state lithium batteries, sulfide electrolyte, lithium anode, alloy anode, anode/electrolyte interfaces

摘要:

全固态锂电池(ASSLBs)比目前的液态锂电池具有更高的能量密度与安全性,是下一代能量存储设备的主要研究方向。相较于其他电解质,硫化物固态电解质具有超高离子电导率、硬度低、易加工、界面接触好等特性,是实现全固态电池最有希望的路线之一。然而,硫化物固态电解质与负极的界面问题,如电解质/负极界面的副反应、固-固接触性差以及锂枝晶等是制约硫化物全固态电池实际应用的重要阻碍。本文概述了目前对匹配硫化物电解质的全固态锂电池主流负极材料的研究现状,总结了金属锂、锂合金、含硅负极等基于硫化物电解质的全固态锂电池的发展现状、应用优势、界面问题及主流解决策略,并为下一步基于硫化物固态电解质的全固态锂电池负极材料的研发与界面问题的解决提供了指导性建议。
