摘　　要：全固态锂金属电池具有较高的安全性和稳定性,是替代传统锂离子电池成为下一代储能装置的理想选择。然而,固态电解质相较于液体电解液而言,其较低的离子电导率仍然是阻碍全固态锂金属电池得到快速发展的一个关键。综述了不同类型固态电解质离子传输机理,总结了提高固态电解质电导率的改进策略和最新研究进展,归纳了改善固态电解质离子传输性能的技术路线,并对未来新型固态电解质的设计与发展作了展望。All-solid-state lithium metal batteries have strong safety and stability,are an ideal selection to replace traditional lithium-ion batteries as next-generation energy storage devices.However,compared with liquid electrolytes,solid-state electrolytes have low ionic conductivity,which is still a key impedi-ment to the rapid development of all-solid-state lithium metal batteries.This paper reviews the ion trans-port mechanisms of different types of solid electrolytes,summarizes the improvement strategies and the latest research progress in enhancing the conductivity of solid electrolytes,and concludes the technical routes to improve the ion transport performance of solid electrolytes,making an outlook to the design and development of new types of solid electrolytes in the future.
