Suppressing dendrite growth for fast cycling of lithium‐metal batteries

As the electric vehicle era enters full scale, demand is increasing for batteries that can travel farther and last longer. Lithium-metal batteries have been attracting attention as a next-generation technology capable of surpassing the capacity limits of existing lithium-ion batteries. However, during the charging process, needle-shaped crystals called dendrites grow, shortening battery life and increasing the risk of fire, which has been identified as the biggest obstacle to commercialization. A Korean research team has developed a key technology that can solve this challenge.
