The aging of lithium-ion batteries significantly impacts their performance, safety, and lifespan. Temperature and current intensity during charge and discharge cycles are key factors driving capacity degradation and safety risks, including overheating and thermal runaway. This study examines how these parameters influence battery aging, revealing that higher charge/discharge rates accelerate degradation more than temperature increases. Under moderate conditions (25 ℃, 1C), 30% capacity loss occurred after about 2100 cycles, providing a baseline for battery longevity. The findings highlight the importance of adhering to manufacturer-recommended operating limits to enhance durability and safety. Future research should explore additional factors, such as mechanical stress and humidity, to develop strategies for optimizing battery performance and extending lifespan.

摘要

The aging of lithium-ion batteries significantly impacts their performance, safety, and lifespan. Temperature and current intensity during charge and discharge cycles are key factors driving capacity degradation and safety risks, including overheating and thermal runaway. This study examines how these parameters influence battery aging, revealing that higher charge/discharge rates accelerate degradation more than temperature increases. Under moderate conditions (25 ℃, 1C), 30% capacity loss occurred after about 2100 cycles, providing a baseline for battery longevity. The findings highlight the importance of adhering to manufacturer-recommended operating limits to enhance durability and safety. Future research should explore additional factors, such as mechanical stress and humidity, to develop strategies for optimizing battery performance and extending lifespan.
