Mechanism of battery expansion failure due to excess solid electrolyte interphase growth in lithium-ion batteries
Revealing the aging and failure mechanisms of lithium-ion batteries is crucial for extending battery life and improving battery safety. This paper presents a mechanism of solid electrolyte interphase (SEI) film overgrowth and battery failure caused by deep aging of cylindrical batteries. Firstly, multiple 18650-type cylindrical battery accelerated aging experiments were designed. Differential voltage analysis (dV/dQ) and electrochemical impedance spectroscopy (EIS) are used to investigate battery degradation mechanisms non-destructively. Secondly, batteries under different degradation degrees were disassembled, and the scanning electron microscope (SEM), liquid nitrogen cooled argon-ion cross-sectional polishing, and X-ray photoelectron spectroscopy (XPS) technology were used to investigate the surface and cross-sectional SEI evolution of electrodes. Obvious increases in SEI thickness and resistance occur when the battery capacity fade is less than 30 %. Finally, the mechanism of excessive growth of SEI on the graphite negative electrode surface of the cylindrical battery, leading to the expansion and rupture failure of the metal shell, was revealed. This work provides crucial insights for the safe service, management, and residual value assessment of lithium-ion batteries throughout their entire lifecycle.
期刊介绍:
eTransportation is a scholarly journal that aims to advance knowledge in the field of electric transportation. It focuses on all modes of transportation that utilize electricity as their primary source of energy, including electric vehicles, trains, ships, and aircraft. The journal covers all stages of research, development, and testing of new technologies, systems, and devices related to electrical transportation.
The journal welcomes the use of simulation and analysis tools at the system, transport, or device level. Its primary emphasis is on the study of the electrical and electronic aspects of transportation systems. However, it also considers research on mechanical parts or subsystems of vehicles if there is a clear interaction with electrical or electronic equipment.
Please note that this journal excludes other aspects such as sociological, political, regulatory, or environmental factors from its scope.
