This study investigates long-term capacity degradation of lithium-ion batteries after low temperature exposure subjected to various C-rate cycles. Findings reveal that low temperature exposure accelerates capacity degradation, especially with increased C-rates or longer exposure durations.
These extreme conditions include preloading force , overcharging , and high/low temperatures , . At low temperatures, the performance metrics of lithium-ion batteries, such as capacity, output power, and cycle life, deteriorate significantly.
Lithium-ion batteries are popular in modern-day applications, but many users have experienced lithium-ion battery failures. The focus of this article is to explain the failures that plague lithium-ion batteries. Millions of people depend on lithium-ion batteries. Lithium-ion is found in mobile phones, laptops, hybrid cars, and electric vehicles.
Root cause 1: High self-discharge, which causes low voltage. Solution: Charge the bare lithium battery directly using the charger with over-voltage protection, but do not use universal charge. It could be quite dangerous. Root cause 2: Uneven current.
Lithium-ion batteries can experience overvoltage and undervoltage effects. As noted in Figure 1, the operating voltage and temperature of the battery must be maintained at the point marked with the green box. If it is not, the cells can be damaged. Figure 1.

Despite being popular and effective, lithium-ion batteries deteriorate over time for a number of reasons. Cycling, or the charge–discharge cycle that a battery experiences throughout its lifespan, is one important component.
