Title:
ALL-SOLID BATTERY
Document Type and Number:
Japanese Patent JP2011154902
Kind Code:
A
Abstract:

To provide an all-solid battery capable of imparting uniform surface pressure to a unit cell without lowering energy density.

The all-solid battery includes at least one unit cell having a solid electrolyte layer existing between a positive electrode layer and a negative electrode layer. The positive electrode layer, the negative electrode layer and the solid electrolyte layer include sulfide based solid electrolyte as electrolyte. In at least one of the positive electrode layer, the negative electrode layer and the solid electrolyte layer, the Young's modulus of the sulfide based solid electrolyte in an outer periphery region of the layer is smaller than the Young's modulus of the sulfide based solid electrolyte in an inside region located inside the outer periphery region.
