Safety in Lithium-Ion Batteries: Thermal Leakage and Post-Incident Intervention Strategies

Safety in Lithium-Ion Batteries

Abstract

The article emphasizes that rechargeable batteries are the most efficient and practical solutions for various storage applications. It is highlighted that Lithium-Ion Batteries (LIBs) are widely used for portable electronic devices and also serve as the main technology for hybrid, plug-in hybrid, or fully electric vehicles. Despite the advantages of energy and power density, LIBs are noted to have safety disadvantages such as having a flammable electrolyte and being thermally unstable under certain operating conditions. Particularly, significant incidents in confined spaces like aircraft and automobiles have raised awareness of potential issues associated with LIBs. The article also mentions a series of incidents involving thermal leakage and fire events being reported.

The article indicates some recommendations for the safe use of LIBs, including proper charging and discharging, avoiding misuse, using high-quality materials and manufacturing, ensuring good ventilation, and providing education and awareness. Additionally, information is provided about various methods and technologies that can be used to prevent thermal leakage. These methods include Battery Management Systems (BMS), Solid Electrolyte Interface, Chemical Additives, and Physical Security Systems.

In the final section of the article, intervention methods for post-thermal leakage incidents are discussed. These interventions include effective use of fire extinguishing systems, evacuation of hazardous areas, dispatching professional emergency teams to the scene, and detailed assessment of damage. It is emphasized that these interventions should be carried out by trained personnel in accordance with established safety protocols.
