PURPOSE:To provide an electrode excellent in workability, lightweight, and having a high volume energy density and large strength by using a metal fiber sintered porous sheet for a current collector forming the electrode for a battery together with an electrode active material. CONSTITUTION:An electrode for a secondary battery is formed with at least an electrode active material and a current collector. A metal fiber sintered porous sheet having the porosity of 30-70% and the fiber diameter of 50mum is used for the current collector. The electrode active material homogeneously dispersed with one or more kinds of inorganic active materials having the average grain size of 10mum or below and the maximum grain size of 30mum or below in at least one kind of conducting polymer matrix having an electrochemical oxidation reduction property is used. The electrode for the secondary battery excellent in workability, lightweight, and having a high volume energy density and large strength is obtained. |
