摘　　要：高安全和高能量密度的锂电池是加快能源转型的重要支撑技术。但是锂电池存在电、化、力和热失效行为,导致电池容量损失、寿命下降和安全性降低,严重阻碍了高能量密度和高安全锂电池的发展。本文从正极与负极协同作用的视角,阐述了锂电池中电/化/力/热串扰行为的最新研究进展及相应的解决策略,对比分析了使用电解液的常规锂电池与使用固态电解质的全固态锂电池在电/化/力/热串扰失效行为方面的相似之处与不同之处,并且总结了电/化/力耦合串扰行为的新观点,展望了进一步深刻认识并解决锂电池电/化/力/热耦合串扰行为的重要研究方向。Lithium batteries with high safety and high energy density are important energy storage technologies supporting the speeding-up of energy transformation.However,the electrical,chemical,mechanical,and thermal failure behaviors of lithium batteries decrease the capacity,cycle life,and safety,which seriously hinders the development of high energy density and high safety lithium batteries.Herein,the latest research progress of electrical/chemical/mechanical/thermal crosstalk behavior in lithium batteries and the corresponding solution strategies are summarized from the perspective of synergistic effect between cathode and anode.Furthermore,the similarities and differences of electrical/chemical/mechanical/thermal crosstalk failure behaviors between conventional lithium batteries using liquid electrolyte and all-solid-state lithium batteries using solid electrolyte are compared and analyzed.Moreover,a new view of electrical/chemical/mechanical coupling crosstalk behavior is summarized.Finally,the important research directions to further understanding and solving the electrical/chemical/mechanical/thermal coupling crosstalk behavior of lithium batteries is prospected.
