South Korea launches fire-resistant EV battery that retains 87% of power after 1000 cycles
Researchers at South Korea’s Daegu Gyeongbuk Institute of Science and Technology (DGIST) have developed a three-layer solid polymer electrolyte containing a lithium-ion battery that can self-extinguish in the event of a fire and is less likely to explode. According to a press release, this battery has a longer lifespan than traditional lithium-ion batteries.
Lithium-ion (Li-ion) batteries are a key component of our clean energy transition, replacing fossil fuels with renewable, carbon-free energy. These batteries are made from abundantly available lithium and offer the most energy-dense storage option available to date, allowing them to power everything from smartphones to electric cars and more.


However, lithium-ion batteries use liquid electrolytes that contain organic materials that can pose a fire hazard. The separators used to separate the electrodes are also susceptible to damage and can short out and cause explosions. This has raised concerns about the use of lithium-ion battery packs in large-scale energy storage solutions.
