Highly Cyclable All‐Solid‐State Battery with Deposition‐Type Lithium Metal Anode Based on Thin Carbon Black Layer

A thin carbon black (CB) layer on a metal current collector is used as a substrate of a deposition‐type Li metal anode for a sulfide‐based all‐solid‐state battery (ASSB). In this ASSB, the capacity of the CB layer is set to ≈5–10% of the cathode. Therefore, the anode soon overcharges and a large pro...
