摘要/Abstract

摘要：

固态聚合物电解质(solid polymer electrolytes，SPEs)具有不易泄漏、易加工、抑制锂枝晶生长等优点，能提高固态金属锂电池(solid-state lithium metal batteries，SSLMBs)的循环寿命和安全性。导电锂盐作为SPEs的必要组分之一，不仅能够为其离子输运提供锂离子源，而且能够在电极表面发生化学或电化学反应，参与电极/SPE界面膜的构建。因此，导电锂盐的分子结构对于调控SPEs的基础物理和电化学性质及其与电极材料的界面性能有着重要的影响。结合本团队在SPEs导电锂盐领域的相关研究工作，本文主要介绍全氟代和部分氟代磺酰亚胺锂盐作为SPEs导电盐的研究进展，并探讨了SPEs导电锂盐的未来发展方向。

Abstract:

Solid polymer electrolytes (SPEs) has several distinct advantages, including no-leakage, ease of use, and suppression of lithium dendrite growth, all of which are important for improving the cycling life and safety of solid-state lithium metal batteries. Conducting lithium salts, as one of the most essential components of SPEs, could not only act as lithium-ion sources for the transportation of ionic species but also participate in the formation/construction of electrode/SPEs interphases. As a result, the chemical structures of lithium salts are critical for regulating the physical and electrochemical properties of SPEs, as well as their interfacial properties with electrode materials. This work focuses mainly on the research progress of conducting lithium salts, including perfluorinated and partially fluorinated sulfonimide salts, based on our experience in the field of SPEs. Future directions in conducting salt design for SPEs are also discussed.

Key words: solid-state lithium metal batteries, solid polymer electrolytes, conducting lithium salts, sulfonimide
