This work comprehensively investigates the failure mechanism of cell sudden death under different degradation paths and its impact on cell performances. Multi-angle characterization analysis shows that lithium plating is the primary failure mechanism of battery sudden death under different degradation paths.
In this work, we discovered, for the first time, that electrode edge effects play an important role in the failure of Li-metal batteries. The dead Li formed on the edge of Cu substrate was systematically investigated through SEM, energy-dispersive X-ray (EDX) spectroscopy, and 2D X-ray photoelectron spectroscopy (XPS).
On the other hand, lithium-ion batteries also experience catastrophic failures that can occur suddenly. Catastrophic failures often result in venting of the electrolyte, fire, or explosion.
They are also grateful to all of the anonymous reviewers for providing useful comments and suggestions that resulted in the improved quality of this paper. Electrode material aging leads to a decrease in capacity and/or a rise in resistance of the whole cell and thus can dramatically affect the performance of lithium-ion batteries.
This capacity fade phenomenon is the result of various degradation mechanisms within the battery, such as chemical side reactions or loss of conductivity , . On the other hand, lithium-ion batteries also experience catastrophic failures that can occur suddenly.
This work conducts an in-depth investigation into the cell sudden death mechanism under different degradation paths and its impact on cell electrochemical performances and thermal safety. Through multi-angle characterization analysis, it has been determined that lithium plating is the common and severe failure mechanism during sudden death.
