Title:
電気化学装置用電極、固体電解質/電極接合体及びその製造方法
Document Type and Number:
Japanese Patent JP5181413
Kind Code:
B2
Abstract:
In an electrode in electrochemical device, particularly an anode lithium ion secondary battery, a cathode for use in alkali storage battery, an electrode for use in fuel cell, or a capacitor electrode, a metal structure has nano size micro-pillars is constructed with an electrode active material being formed on the surface of the metal structure. The metal structure having nano size micro-pillars can be formed, for example, by forming a metal layer as an electrode material by plating to the surface of a substrate having pores and then removing the substrate by dissolution, the metal filled in the pores of the substrate to form a group of micro-pillars. And the active material can be formed by depositing metal by plating. Since the active material is in direct contact with the conductive skeleton, the conducting agent for connecting the active materials to each other may not be added at all.
