Self-healing is the capability of materials to repair themselves after the damage has occurred, usually through the interaction between molecules or chains. Physical and chemical processes are applied for the preparation of self-healing systems. There are different approaches for these systems, such as heterogeneous systems, shape memory effects, hydrogen bonding or covalent-bond interaction, diffusion, and flow dynamics. Self-healing mechanisms can occur in particular through heat and light exposure or through reconnection without a direct effect. The applications of these systems display an increasing trend in both the R&D and industry sectors. Moreover, self-healing systems and their energy storage applications are currently gaining great importance. This review aims to provide general information on recent developments in self-healing materials and their battery applications given the critical importance of self-healing systems for lithium-ion batteries (LIBs). In the first part of the review, an introduction about self-healing mechanisms and design strategies for self-healing materials is given. Then, selected important healing materials in the literature for the anodes of LIBs are mentioned in the second part. The results and future perspectives are stated in the conclusion section.
自修复是指材料在受损后自行修复的能力，通常是通过分子或链之间的相互作用来实现。物理和化学过程被用于制备自修复系统。这些系统有不同的方法，如非均相系统、形状记忆效应、氢键或共价键相互作用、扩散和流动动力学。自修复机制尤其可以通过热和光照射或通过无直接作用的重新连接而发生。这些系统的应用在研发和工业领域都呈现出增长趋势。此外，自修复系统及其能量存储应用目前正变得极为重要。鉴于自修复系统对锂离子电池（LIBs）至关重要，本综述旨在提供有关自修复材料及其电池应用的最新进展的一般信息。在综述的第一部分，介绍了自修复机制和自修复材料的设计策略。然后，在第二部分提到了文献中用于LIBs阳极的选定重要修复材料。结论部分阐述了结果和未来展望。
