Lithium Metal Battery Allows Cold Charging

Lithium metal batteries are the next generation of battery after the lithium-ion battery. They use a lithium anode and have higher energy density but have problems with dendritic growth, low efficiency, and low cycle life. To solve these problems, researchers developed a self-assembling monolayer that is electrochemically active so that it can decompose into its proper components and protect the surface of the lithium anode.
