Thin-film Battery

摘要

A battery has a cathode layer deposited on a first current collector layer, an anode layer, and a solid-state electrolyte layer between the cathode layer and the anode layer. The cathode layer has a first projection and the anode layer has a second projection. The solid-state electrolyte layer has a first recess complementary to the first projection and a second recess complementary to the second projection. The battery also has a second current collector layer deposited over the anode layer.
