Battery safety has become a focal issue for the large-scale application of new energy vehicles and electrochemical energy storage. During battery operation, it may face various extreme application scenarios, such as internal short circuits caused by compression and impact, exothermic side reactions induced by the decomposition of the SEI (Solid Electrolyte Interphase) film in high-temperature environments, and the promotion of lithium dendrite growth in low-temperature or overcharging situations. As the conditions of misuse persist, lithium dendrites on the anode, internal short circuit hotspots, and internal reactions gradually evolve, further leading to severe incidents such as thermal runaway. This study, in conjunction with operational environments, explores the evolution mechanisms and influencing factors of these battery damages in depth. The process of battery damage is also accompanied by degradation in battery capacity and internal resistance, revealing deviation characteristics in battery pack consistency. However, experimental findings indicate that under conditions of slight misuse with a lower degree of severity, the inconsistency characteristics are not prominent and can easily be overlooked. To provide early warnings for misused battery cells, this study analyzes the voltage inconsistency deviation characteristics of abused batteries over time and attempts to develop warning algorithms based on these characteristics.
