Despite rapid development of electric vehicles (EVs), lithium-ion (Li-ion) batteries are a fire and explosion risk. Among the approaches to tackle this issue, Korean researchers have used semiconductor technology to improve their safety. A research team from the Korea Institute of Science and Technology (KIST) led by Dr. Joong Kee Lee of the Center for Energy Storage Research has succeeded in inhibiting the growth of dendrites, crystals with multiple branches that cause EV battery fires by forming protective semiconducting passivation layers on the surface of Li electrodes.Despite rapid development of electric vehicles (EVs), lithium-ion (Li-ion) batteries are a fire and explosion risk.
