Abstract
Official abstract text for this publication.
To provide a highly reliable power storage device, to improve the security of a power storage device, and to suppress deterioration of a power storage device, a power storage device includes, inside an exterior material, a positive electrode, a negative electrode facing the positive electrode, an electrolyte solution between the positive electrode and the negative electrode, and an adsorbent. A separation body which is impermeable to the electrolyte solution and permeable to a gas is provided between the electrolyte solution and the adsorbent.
First claim
Opening claim text (preview).
What is claimed is: 1. A power storage device comprising: an exterior material; a positive electrode; a negative electrode facing the positive electrode; an electrolyte solution between the positive electrode and the negative electrode; and an adsorbent, wherein the positive electrode, the negative electrode, the electrolyte solution, and the adsorbent are provided inside the exterior material, wherein a separation body is provided between the electrolyte solution and the adsorbent, wherein the separation body is impermeable to the electrolyte solution and permeable to a gas, and wherein an entire surface of the adsorbent is coated with the separation body. 2. The power storage device according to claim 1 , wherein a space surrounded by the separation body is provided inside the exterior material, and wherein the adsorbent is provided in the space. 3. The power storage device according to claim 1 , wherein a space surrounded by an inner wall of the exterior material and the separation body is provided inside the exterior material, and wherein the adsorbent is provided in the space. 4. The power storage device according to claim 1 , wherein the adsorbent coated with the separation body is fixed to a support, and wherein the support is provided to overlap with the positive electrode and the negative electrode. 5. The power storage device according to claim 4 , wherein the support is provided between the positive electrode and the negative electrode to overlap with the positive electrode and the negative electrode. 6. A power storage device comprising: an exterior material; a positive electrode; a negative electrode facing the positive electrode; an electrolyte solution between the positive electrode and the negative electrode; and an adsorbent including zeolite, wherein the positive electrode, the negative electrode, the electrolyte solution, and the adsorbent are provided inside the exterior material, wherein a separation body including cellulose is provided between the electrolyte solution and the adsorbent, wherein the separation body is impermeable to the electrolyte solution and permeable to a gas, and wherein an entire surface of the adsorbent is coated with the separation body. 7. The power storage device according to claim 6 , wherein a space surrounded by the separation body is provided inside the exterior material, and wherein the adsorbent is provided in the space. 8. The power storage device according to claim 6 , wherein a space surrounded by an inner wall of the exterior material and the separation body is provided inside the exterior material, and wherein the adsorbent is provided in the space. 9. The power storage device according to claim 6 , wherein the adsorbent coated with the separation body is fixed to a support, and wherein the support is provided to overlap with the positive electrode and the negative electrode. 10. The power storage device according to claim 9 , wherein the support is provided between the positive electrode and the negative electrode to overlap with the positive electrode and the negative electrode.
