Abstract
A flexible power storage unit is obtained. Projections whose ridgelines extend in a first direction are provided on the front and the back of the power storage unit and depressions whose valley lines extend in a second direction are provided on the sides of the power storage unit. The projections and depressions are provided such that the ridgelines of the projections or extended lines of the ridgelines intersect with the valley lines of the depressions or extended lines of the valley lines.
Claims23
A power storage unit comprising:
- an exterior body;
- a positive electrode;
- a negative electrode;
- a separator;
- and
- an electrolyte solution,
- wherein the positive electrode, the negative electrode, the separator, and the electrolyte solution are surrounded by the exterior body,
- wherein the exterior body has a projection whose ridgeline extends in a first direction and a depression whose valley line extend in a second direction, and
- wherein the ridgeline or an extended line of the ridgeline intersects with the valley line or an extended line of the valley line.
A power storage unit comprising:
- an exterior body;
- a positive electrode;
- a negative electrode;
- a separator;
- and
- an electrolyte solution,
- wherein the positive electrode, the negative electrode, the separator, and the electrolyte solution are surrounded by the exterior body,
- wherein the exterior body comprises a first ridgeline and a first valley line each extending in a first direction, and a second ridgeline and a second valley line each extending in a second direction,
- wherein the first ridgeline or an extended line of the first ridgeline intersects with the second valley line or an extended line of the second valley line, and
- wherein the first valley line or an extended line of the first valley line intersects with the second ridgeline or an extended line of the second ridgeline.
A power storage unit comprising:
- an exterior body;
- a positive electrode;
