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.
Safety test standards are designed to ensure that certified LIBs have sufficiently low risks of safety accidents in specified kinds of thermal runaway induction and expansion situations. Battery safety standards are constantly being updated and optimized, because current tests cannot fully guarantee their safety in practical applications.
Based on a hazard analysis, incorporate appropriate safety-related design and testing criteria into battery pack and device design, with the design objective of increasing the safety margin and system reliability during the battery pack's entire life cycle.
Battery safety is profoundly determined by the battery chemistry , , , its operating environment, and the abuse tolerance, . The internal failure of a LIB is caused by electrochemical system instability, .
Since undesirable and uncontrollable heat and gas generation from various parasitic reactions are the leading causes of LIB safety accidents, efforts to improve battery safety need to focus on ways to prevent LIBs from generating excessive heat, keeping them working at a suitable voltage range, and improving their cooling rates. 4.1.
