Japanese Patent JP2021034328
Kind Code:
A
Abstract:
To provide an all-solid battery superior in charge and discharge cycle characteristics, and a system having the all-solid battery.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 has a mold of a positive electrode mixture containing a lithium nickel cobalt manganese composite oxide of a particular composition which is a positive electrode active material, a solid electrolyte and a conductive assistant, and containing no resin binder, otherwise containing a resin binder of which the content is 0.5 mass% or less. The negative electrode has a mold of a negative electrode mixture containing a lithium titanium oxide which is a negative electrode active material, a solid electrolyte and a conductive assistant, and containing no resin binder, otherwise containing a resin binder of which the content is 0.5 mass% or less. The all-solid battery is charged with a voltage of 2.85 V or less for use.SELECTED DRAWING: Figure 1
