A research team from the Division of Energy & Environmental Technology at DGIST, led by Principal Researcher Kim Jae-hyun, has developed an innovative lithium metal battery featuring a “triple-layer solid polymer electrolyte.” This advancement promises significant improvements in both fire safety and battery lifespan, positioning it as a potential game-changer for applications in electric vehicles and large-scale energy storage systems.
Traditional solid polymer electrolyte (SPE) batteries have faced persistent challenges, particularly in ensuring optimal contact between the battery’s electrodes. This is critical in preventing the formation of “dendrites”—tree-like structures of lithium that form during repeated charging and discharging cycles. These dendrites can cause internal short circuits, potentially leading to fires or even explosions, posing a significant safety hazard.
