Title:
ALL-SOLID TYPE SECONDARY BATTERY AND CHARGING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2020113415
Kind Code:
A
Abstract:
To provide an all-solid type lithium secondary battery, capable of suppressing peeling of a negative electrode collector from a negative active material layer.SOLUTION: In order to solve the problem, an all-solid type lithium secondary battery comprises: a positive electrode layer; a negative electrode layer; and a solid electrolyte layer arranged between the positive electrode layer and the negative electrode layer. The negative electrode layer includes: a plate-like and a foil-like negative electrode collector; a negative electrode active material layer laminated on a solid electrolyte layer side of the negative electrode collector; and a peeling prevention layer formed on a front face on the negative electrode active material layer side of the negative electrode collector. A rigidity of the peeling prevention layer is smaller than that of the negative electrode collector.SELECTED DRAWING: Figure 1
