Battery inconsistency is one of the main factors affecting the performance and safety of BESS systems. Every step, from materials to manufacturing and usage conditions, influences battery consistency . The hazards of battery pack inconsistency include increased system failure rates, reduced performance, and accelerated lifespan decay.
An overview of battery safety issues. Battery accidents, disasters, defects, and poor control systems (a) lead to mechanical, thermal abuse and/or electrical abuse (b, c), which can trigger side reactions in battery materials (d).
The external environment (which controls the temperature, voltage, and electrochemical reactions) is the leading cause of internal disturbances in batteries . Thus, the environment in which the battery operates also plays a significant role in battery safety.
The hazards of battery pack inconsistency include increased system failure rates, reduced performance, and accelerated lifespan decay. The material stability of LIBs is another challenge, as current battery materials tend to decompose at high temperatures, releasing flammable gases and increasing the risk of fire and explosion .
The primary challenges for these second-use batteries include safety, performance, and compatibility with various applications . Batteries used in secondary applications may experience different stress and load conditions in new environments, requiring a reassessment of their safety performance.
Therefore, if the cell working process is regarded as a reaction sequence driven by the Fermi-level difference, the essence of the battery safety problem is the disorder of the reaction sequence that is accidentally triggered. There must be a safety range delineated by the Fermi level of the characteristic reactions of the electrode materials.
