Abstract
The invention provides a power storage device capable of preventing reduced energy efficiency of the power storage device and of avoiding variations in temperature distribution. The power storage device includes a positive electrode and a negative electrode, and a solid electrolyte layer placed between the positive electrode and the negative electrode and including a group of particles, wherein the density of particles in a first area of the solid electrolyte layer is lower than the density of particles in a second area which has higher heat radiation than the first area.
Claims11
A power storage device comprising:
- a positive electrode and a negative electrode;
- and
- a solid electrolyte layer placed between the positive electrode and the negative electrode and including a group of particles,
- wherein a density of particles in a first area of the solid electrolyte layer is lower than a density of particles in a second area which has higher heat radiation than the first area.
A power storage device comprising:
- a positive electrode and a negative electrode;
- and
- a solid electrolyte layer placed between the positive electrode and the negative electrode and including a group of particles,
- wherein a thickness of a first area of the solid electrolyte layer is larger than a thickness of a second area which has higher heat radiation than the first area.
A power storage device comprising:
- a positive electrode and a negative electrode;
- and
- a solid electrolyte layer placed between the positive electrode and the negative electrode and including a group of particles,
- wherein a material of the particles in a first area of the solid electrolyte layer is different from a material of the particles in a second area which has higher heat radiation than the first area such that a resistance value in the first area is higher than a resistance value in the second area.
