METHOD FOR FORMING POSITIVE ELECTRODE FOR THIN FILM LITHIUM-ION RECHARGEABLE BATTERY, POSITIVE ELECTRODE FOR THIN FILM LITHIUM-ION RECHARGEABLE BATTERY, AND THIN FILM LITHIUM-ION RECHARGEABLE BATTERY

摘要

A method for forming a positive electrode for a thin film lithium-ion rechargeable battery includes forming a positive electrode power collection layer, forming a first positive electrode active material layer by covering the positive electrode power collection layer with a first positive electrode active material that contains lithium cobalt oxide, forming a second positive electrode active material layer that has a thickness of 20 nm or greater and 60 nm or less by covering the first positive electrode active material layer with a second positive electrode active material that contains aluminum and lithium cobalt oxide, and heating a lamination body that includes the positive electrode power collection layer, the first positive electrode active material layer, and the second positive electrode active material layer.
