| 摘要 | A positive electrode system of an electric storage device includes first and second positive electrodes. The first and second positive electrodes include current collectors, and first and second positive-electrode mixture layers, respectively. The negative electrode system of the electric storage device has a negative electrode including a current collector and a negative-electrode mixture layer. The first positive electrode and the second positive electrode are arranged across the negative electrode. The first positive-electrode mixture layer and the second positive-electrode mixture layer are connected to each other, and of different types. Through-holes are formed in the current collector of the negative electrode arranged between the first positive-electrode mixture layer and the second positive-electrode mixture layer. | ||
