New Breakthrough in Battery Safety
LG Chem Finds Key to Suppressing Thermal Runaway in Batteries
LG Chem, a leading manufacturer of lithium-ion batteries, has made a significant breakthrough in understanding the root cause of thermal runaway in batteries. Thermal runaway is a phenomenon where batteries overheat and release gas, potentially causing a fire or explosion. The key to suppressing thermal runaway is to identify the triggers and develop strategies to mitigate these triggers.
Understanding the Triggers of Thermal Runaway
Thermal runaway is often caused by three main triggers: mechanical stress, electrical stress, and chemical stress. Mechanical stress occurs when batteries are damaged or subjected to physical strain, such as crushing or bending. Electrical stress arises from electrical discharges, such as short circuits or overcharging. Chemical stress is caused by the accumulation of impurities or chemical reactions within the battery.
LG Chem’s Discovery
LG Chem’s researchers have discovered that the chemical stress trigger is the primary cause of thermal runaway. They found that the impurities in the battery electrolyte, a key component of the battery, are responsible for the chemical reactions that lead to thermal runaway.
Suppression Strategy
To suppress thermal runaway, LG Chem has developed a strategy that involves developing new electrolyte materials and optimizing battery design. The new electrolyte materials will be designed to reduce chemical stress by minimizing the presence of impurities. Optimizing battery design will involve improving the battery’s structure and architecture to reduce the risk of mechanical and electrical stress.
Future Development
LG Chem plans to apply its new understanding and suppression strategy to develop safer and more reliable batteries for various applications, including electric vehicles, renewable energy systems, and consumer electronics.
Conclusion
LG Chem’s breakthrough in understanding and suppressing thermal runaway is a significant step forward in battery safety. The company’s research and development efforts aim to create safer and more reliable batteries that can mitigate the risks associated with thermal runaway. This advancement is expected to have a profound impact on the development of electric vehicles and other applications that rely on lithium-ion batteries.
