Lithium-ion battery

as a kind of important energy storage device

plays a crucial role in such fields as power system regulation

utilization of renewable energy and electric transportation. In view of such problems of the lithium-ion battery as various failure phenomena

leading to performance degradation

shortened lifespan

and potential safety hazards during the long term application period

in this paper the common failure mode and its corresponding failure mechanism of the lithium-ion battery

including the aspects of including structural damage

electrolyte degradation

and thermal runaway

is comprehensively described. The performance optimization of the lithium-ion battery in the future is forecasted

aiming to provide positive impetus for the further development of failure analysis technology for energy storage lithium-ion battery.
