Free QuoteEnhancement of battery safety: Battery aging can lead to changes in the internal structure and physical properties of batteries, thereby increasing the risk of battery failure or thermal runaway.
The main aging mechanisms of fast charging batteries are lithium plating and loss of active materials. Of course, accelerated aging would be pointless if the battery suffers significant lithium plating and active materials loss .
In summary, temperature, C-rate, and DOD significantly impact the aging of lithium-ion batteries. Therefore, controlling these operating conditions is key to extending battery life and maintaining optimal performance.
In real cases of battery aging, it is unlikely that the aging mechanisms will remain constant. Hence, it is more suitable to employ approaches that rely on acquiring dynamic data from the battery, such as equivalent circuit models and data-driven methods.
For example, in order to store more energy, most LIBs used in ESSs are designed to be energy dense with poor rate performance. Consequently, they are not suitable for high current rate acceleration but rather more appropriate for SOC and DOD acceleration. For temperature, it is suitable for the accelerated aging of most types of batteries.
These aging phenomena will result in increased battery resistance, battery short circuit, and other consequences . Separator aging is generally not considered in accelerated aging studies. This is because it has little impact on battery capacity in the early stage of battery lifetime.
