LG Chem announced a significant advancement in battery safety with the development of a new ‘safety-enhanced functional layer’ aimed at suppressing thermal runaway. This breakthrough, achieved in collaboration with Pohang University of Science and Technology, introduces a thin composite layer designed to act as a fuse when temperatures rise beyond normal levels, blocking the flow of electricity and preventing overheating.
Thermal runaway, a critical issue in lithium-ion batteries, particularly those used in electric vehicles (EVs), can lead to fires or explosions if left unchecked. LG Chem’s new material, only 1㎛ thick, has been tested successfully, showing promising results in impact and penetration tests by preventing fire or extinguishing sparks.
With the safety material already verified for mobile batteries, LG Chem plans to continue testing for large-capacity EV batteries, with the potential to commercialize the technology soon. The innovation could boost consumer confidence in EV safety and contribute to the industry’s growth, as enhanced safety features become increasingly important.
The research, published in Nature Communications, underscores the importance of this development in shaping future battery safety standards.
