全固体電池及びその製造方法
Document Type and Number:
Japanese Patent JP7327005
Kind Code:
B2
Abstract:
To provide an all-solid battery having a high charge/discharge efficiency, and a manufacturing method thereof.SOLUTION: An all-solid battery, in which a precipitation-dissolution reaction of metallic lithium is utilized as a negative electrode reaction, comprises: a positive electrode including a positive electrode layer; a negative electrode including a negative electrode current collector and a negative electrode layer; and a solid electrolyte layer disposed between the positive and negative electrode layers. The negative electrode layer contains, as a negative electrode active material, a β single phase alloy of metallic lithium and metallic magnesium. In the all-solid battery, the proportion of atoms of a lithium element in the alloy is 81.80-99.97 atomic% when the all-solid battery is fully charged.SELECTED DRAWING: Figure 2
