Abstract
A power storage device includes: an electrolyte layer; and an electrode consisted of a current collecting portion and an electrode layer, wherein the thickness of the electrolyte layer is larger at a first position in a plane perpendicular to the stacking direction than at a second position where the heat radiation is higher than at the first position, and the thickness of the current collecting portion is smaller at a position corresponding to the first position than at a position corresponding to the second position.
Claims14
A power storage device comprising:
- an electrolyte layer having a thickness;
- and
- an electrode constituted of a current collecting portion and an electrode layer, the current collecting portion and the electrode layer having thicknesses, wherein
- the thickness of the electrolyte layer is larger at a first position in a plane perpendicular to a stacking direction in which components of the power storage device are stacked than at a second position at which heat radiation is higher than at the first position, and
- the thickness of the current collecting portion is smaller at a position corresponding to the first position than at a position corresponding to the second position.
