Document Type and Number:
Japanese Patent JP7149317
Kind Code:
B2
Abstract:
To provide a solid-state battery capable of achieving a higher capacity. A solid-state battery includes a positive electrode and a negative electrode. The positive electrode and the negative electrode each includes a current collector that is a metal porous body having a spiral shape, and an electrode material mixture with which the current collector is filled. The positive electrode and the negative electrode are arranged in combination such that opposing faces of the positive electrode and the negative electrode alternately contact each other in an axial direction of the spiral shape. A pair of the positive electrode and the negative electrode having the above structure are housed in an exterior packaging body having a cylindrical shape to achieve a higher capacity of the solid-state battery.
