The effects of varying initial state of charge and loading speed on battery degradation are also analyzed. It has been observed that a deformation damage degree as low as 3.1 % can cause a significant transient capacity reduction up to 6.3 %. More transient capacity reduction can occur at higher initial state of charge and loading speed.
Based on the transient and progressive degradation behaviors of batteries, the mechanical deformation damage of batteries is classified into three levels, and quantitative damage degree thresholds are established.
Battery degradation refers to the progressive loss of a battery’s capacity and performance over time, presenting a significant challenge in various applications relying on stored energy . Figure 1 shows the battery degradation mechanism. Several factors contribute to battery degradation.
Minor deformation damage effects on battery transient degradation are discussed. SOC and loading rate effects on the transient degradation behaviors are given. Progressive degradation mechanisms of damaged batteries are investigated. Minor deformation damage poses a concealed threat to battery performance and safety.
Another important degrading element is temperature. Higher temperatures hasten chemical processes in the battery, which speed up the deterioration of the electrolytes and electrode materials. In the same way, low temperature, SOC, DOD, and calendar aging also play a vital role in battery degradation.
A predominant focus lies on instances of abrupt capacity reduction attributed to localized, conspicuous deformations in cylindrical batteries. Only a few studies have focused on the evolution of capacity degradation trajectories after minor deformation damage in batteries, and the underlying degradation mechanisms have not been fully elucidated.
