Thermal runaway has plagued the lithium-ion battery industry since its inception. While measures to mitigate safety risks have been advanced along the way, reaching a very high point today, “thermal events” – which generate gas and can potentially escalate to full combustion – have not been rooted out for good.
Now, South Korea’s LG Chem claims to have found a solution to this long-standing issue. The conglomerate announced on Tuesday that its Platform Technology R&D team has developed a temperature-responsive Safety Reinforced Layer (SRL), a material which it describes as capable of suppressing thermal runaway.
It revealed that SRL is a composite material that changes its electrical resistance based on temperature, acting as a “fuse” that blocks the flow of electricity in the early stages of overheating.
