A study of Li-metal batteries by the research team led by Dr. Byung Gon Kim at Next-Generation Battery Research Center of Korea Electrotechnology Research Institute (KERI) was published as a cover paper in the international journal ACS Nano.
While the current Li-ion batteries generate energy by taking Li-ions in and out of the graphite anode based on the intercalation mechanism, the Li-metal battery does not rely on this bulky and heavy graphite but uses metallic Li itself as the anode. As the Li-metal shows 10 times higher theoretical capacity (3,860 mAh/g) than graphite (372 mAh/g), it has steadily gained much attention from areas that need high-capacity batteries, such as electric vehicles and energy storage systems.
