PROBLEM TO BE SOLVED: To provide an electrode for a power storage device of a large capacity and small internal resistance.SOLUTION: By using a porous metal having high porosity and a large specific surface area for a current collector, much amount of polarizable electrode materials are filled in the porous metal to increase a capacity. A porous current collector having a high specific surface area, it is possible to have a large contact area between the polarizable electrode and the porous metal and, as a result, internal resistance is reduced.SELECTED DRAWING: Figure 1 |
