Korea unleashes fire-proof EV battery that holds 87% power after 1000 cycles
Researchers at the Daegu Gyeongbuk Institute of Science and Technology (DGIST) in South Korea have developed a triple-layer solid polymer electrolyte containing a lithium-ion battery that can extinguish itself if it catches fire and is resistant to explosion. The battery also shows better lifespan than conventional lithium-ion batteries, a press release said.
Lithium-ion (Li-ion) batteries are a critical component of the clean energy transition that we have undertaken, replacing fossil fuels with renewable and carbon-free energy. Made from abundantly available lithium, these batteries offer the most energy-dense storage option available to us to date and can power everything from a smartphone to electric vehicles and beyond.
However, Li-ion batteries use liquid electrolytes with organic materials that are at risk of catching fire. The separators used to separate the electrodes are also prone to damage and can lead to short circuits, causing explosions. This has raised concerns about using Li-ion battery packs in large-scale energy storage solutions.
