Lithium-ion batteries (LIBs) with excellent performance are widely used in portable electronics and electric vehicles (EVs), but frequent fires and explosions limit their further and more widespread applications. This review summarizes aspects of LIB safety and discusses the related issues, strategies, and testing standards.
Best working temperatures are between 15°C and 35°C. Proper lithium-ion batteries storage is critical for maintaining an optimum battery performance and reducing the risk of fire and/or explosion. Many recent accidents regarding lithium-ion battery fires have been connected to inadequate storage area or conditions.
Stable LIB operation under normal conditions significantly limits battery damage in the event of an accident. As a result of all these measures, current LIBs are much safer than previous generations, though additional developments are still needed to improve battery safety even further.
Lithium battery fires and accidents are on the rise and present risks that can be mitigated if the technology is well understood. This paper provides information to help prevent fire, injury and loss of intellectual and other property. Lithium batteries have higher energy densities than legacy batteries (up to 100 times higher).
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.
Safety maxim: “Do everything possible to eliminate a safety event, and then assume it will happen” Properly designed Li-ion batteries can be operated confidently with a high degree of safety Thanks for listening… [email protected]
