ALL-SOLID BATTERY
Document Type and Number:
Japanese Patent JP2021034326
Kind Code:
A
Abstract:
To provide a high-capacity all-solid battery superior in output characteristic.SOLUTION: An all-solid battery according to the present invention comprises: a positive electrode; a negative electrode; and a solid electrolyte layer interposed between the positive and negative electrodes. The positive electrode contains a lithium nickel cobalt manganese composite oxide, which is a positive electrode active material of a particular composition, a sulfide-based solid electrolyte, and a conductive assistant. The content of the positive electrode active material in a positive electrode mixture is 60-75 mass%. The negative electrode has a mold of a negative electrode mixture containing a lithium titanium oxide which is a negative electrode active material, a sulfide-based solid electrolyte and a conductive assistant. The content of the negative electrode active material in the negative electrode mixture is 40-60 mass%. The solid electrolyte layer contains a sulfide-based solid electrolyte.SELECTED DRAWING: Figure 1
