Thermal runaway has plagued the lithium-ion battery industry since its inception. Although measures have been gradually taken to reduce safety risks, which today have reached a very high point, ‘thermal events’ – which generate gas and can potentially escalate to complete combustion – have not yet been eradicated for good.
Now South Korea’s LG Chem claims to have found a solution to this long-standing problem. The conglomerate announced Tuesday that its Platform Technology R&D team has developed a temperature-sensitive Safety Reinforced Layer (SRL), a material the company claims is capable of suppressing thermal runaways.
It showed 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.
