摘要
固态电池具有高功率、高能量密度、高安全性等优点,有望成为下一代锂离子电池技术。但现阶段其存在的失效问题,依然限制其广泛应用。本文从锂枝晶、界面问题、正极结构演变和电解质失效等四个方面出发,总结了固态锂电池失效机制及其研究进展,并对固态电池的失效分析的发展进行了展望。
Solid state lithium battery with the advantages of high power density,high energy density and high safety is promising to become thenextgeneration lithium battery technology.However,its current failureproblem still limits its widespread application.In this review,the development of failure mechanisms and research methods for solid state lithium batteries are summarized from the aspects of lithium dendrite growth,interface failure,cathode structure evolution and electrolyte failure.Finally,The development of failure analysis and research progress of the failure mechanisms for solid state lithium batteries are proposed.
