Developing the new energy industry is an important means to achieve the goal of “Double Carbon”, whereas the core of developing the new energy industry lies on advanced energy storage technologies. Ternary material has become a mainstream energy storage material. The research on the instability mechanism of ternary material can provide guidance for the recycle of spent cathode materials. In this paper, the reasons for ternary material instability are introduced, including cation mixing, thermal instability, surface instability, microcrack, etc. Of these reasons, the microcrack is the key source for the instability of ternary material. Besides, the feasible strategies and ways for recycling spent cathode materials are expected.
