摘要:: 随着固态电池、无负极高比能电池、锂基新型电池如锂-氧/锂-硫电池体系、高比能量锂一次电池的发展，锂金属电极材料的研究已经从将其单纯作为液态电池的参比或对电极材料，慢慢地转变为作为更重要的高比容量负极材料，但考虑到锂的安全性以及其自身的体积效应，安全性更高的锂合金电极材料的研究逐渐成为高性能储能器件构筑设计与研究关注的重点。主要基于锂合金电极材料，对近期相关电极材料在锂离子电池、锂空气电池、锂-硫等液/聚合物/固态电池领域的研究进展进行了梳理，比较了各类锂合金材料的优、劣势，以期为相关电极材料的下一步发展提供参考，也为新型高比能量、长循环寿命的储能体系的原理探索与设计提供科学借鉴。

Abstract:: With the development of solid-state battery, without-negative-anode based high specific energy battery, new lithium-based high energy (Li-O2/Li-S) batteries and the high specific energy primary lithium battery, lithium metal electrode materials have been gradually converted from the simple reference and counter electrodes materials to an important negative electrode material within a liquid battery. However, considering the safety of lithium metal and its intrinsic volume effect, the researches of lithium alloy electrode materials have become an efficient strategy to design a new energy storage system with high specific density and cycle stability. Herein, based on lithium alloy electrode materials, this review mainly discussed the development of these electrodes materials in lithium-ion, lithium-air, lithium-sulfur batteries whatever in liquid, gel-polymer or solid-state. Various types of lithium alloy materials were systematically compared and their advantages and disadvantages were summarized, which will provide a superior electrode towards the demand of the ideal storage system with high specific energy and long cycle life.
