PURPOSE:To reduce the production cost and improve the life by performing the process integrally connecting a micro-capsule alloy with a current collector with a hot press in the hydrogen gas atmosphere and concurrently molding and activating an electrode. CONSTITUTION:The process to integrally connect a micro-capsule alloy coated with copper or nickel on the surface of hydrogen storage alloy powder to a current collector with a hot press is performed in the hydrogen gas atmosphere, and an electrode is concurrently molded and activated. The micro-capsule alloy may be used alone, or at least one kind selected from a group of copper powder, nickel powder, PTFE, PEP, polyethylene, polypropylene, and nylon may be mixed at 10wt.% or below to the electrode as a caking agent for use. The hot press temperature is 100-350 deg.C, the hydrogen gas atmosphere is 1-10atm., the hot press pressure is 1t/cm or below, and the press pressure at the time of cooling is set to 200kg/cm or below. |
