Control of Dendritic Growth of the Lithium Metal in All-Solid-State Lithium Metal Batteries: Effect of the Current Collector with Microsized Pores.

The dendritic growth of the Li metal through a separator is a serious issue for the development of rechargeable Li metal batteries in which the Li metal is used as the negative electrode. Several methods have been investigated for this issue; however, it has not been completely solved until now. The all-solid-state battery (ASSB) system is one of the most powerful methods for practical use of the Li metal negative electrode because the solid-state electrolyte (SSE) can mechanically block the dendritic growth of Li metal.
