Korean researchers have ushered in a new era for electric vehicle (EV) battery technology by solving the long-standing dendrite problem in lithium-metal batteries. Lithium-metal batteries replace the graphite anode, a key component of lithium-ion batteries, with lithium metal. Dendrites are tree-like lithium crystals that form on the anode surface during battery charging, negatively affecting battery performance and stability. This technology overcomes the slow charging speed, which was a major limitation of existing lithium-metal batteries, while maintaining high energy density. Je-Young Kim, CTO of LG Energy Solution, said, "The four years of collaboration between LG Energy Solution and KAIST through FRL are producing meaningful results.
