Patent ID: 8007936

Claim:
An electric storage device comprising: a first electric storage component including a first positive-electrode mixture layer and a negative-electrode mixture layer opposite to the first positive-electrode mixture layer; and a second electric storage component that is connected in parallel to the first electric storage component and includes a second positive-electrode mixture layer and a negative-electrode mixture layer opposite to the second positive-electrode mixture layer, wherein the positive-electrode mixture layer contains a positive-electrode active material that allows ions to be reversibly doped thereinto and dedoped therefrom, the negative-electrode mixture layer contains a negative-electrode active material that allows ions to be reversibly doped thereinto and dedoped therefrom, the capacity of the first positive-electrode mixture layer is set higher than the capacity of the second positive-electrode mixture layer, the path resistance of the first electric storage component is set higher than the path resistance of the second electric storage component, and a current collector provided between the first positive-electrode mixture layer and the second positive-electrode mixture layer has a through-hole formed therein.
