锂金属负极的研究策略
摘要:全固态电池由正极材料、固态电解质和锂金属负极组成，锂金属负极是全固态电池的重要组成部分。锂金属负极的成功应用不仅可以提高电池能量密度和安全性能，还能降低现有电化学体系的制造成本，全面取代液态锂离子电池。但在实际的应用过程当中，锂金属负极还存在着下列难以解决的问题：锂枝晶、“死锂”粉末化、体积膨胀和抗空气氧气稳定性。针对以上的问题，综述了先进的锂金属负极研究策略，并给出了解决方案，最后提出了展望。
Abstract：All-solid-state batteries are composed of cathode materials, solid electrolytes and lithium metal anodes. Lithium metal anodes are an important part of all-solid-state batteries. The successful application of lithium metal anode can not only improve the energy density and safety performance of the battery, but also reduce the manufacturing cost of the existing electrochemical system and completely replace the liquid lithium ion battery. However, in the actual application process, the lithium metal negative electrode still has the following difficult to solve problems: lithium dendrites, powdering, volume expansion and air stability. In response to the above problems, this article reviews some advanced lithium metal anode research strategies, gives its own solutions, and finally puts forward a prospect.
