Abstract
The present disclosure relates to a solid-state battery. The solid-state battery includes a cathode active material layer and a solid electrolyte layer adjacent to the cathode active material layer. A surface development ratio (Sdr) of a surface of the cathode active material layer near the solid electrolyte layer is 0.070 or more.
Claims3
A solid-state battery comprising a cathode active material layer and a solid electrolyte layer adjacent to the cathode active material layer, wherein
- a surface development ratio (Sdr) of a surface of the cathode active material layer near the solid electrolyte layer is 0.070 or more.
