ELECTRODE FOR ALKALINE SECONDARY BATTERY

摘要

PURPOSE: To heighten pressure applied in filling of an active material and increase filling density by using a nonwoven fabric web of organic fibers whose strength is increased by applying entangling treatment or heat treatment as a current collector core body of an electrode. CONSTITUTION: Nickel is plated on a core body prepared by applying entangling treatment and/or heat treatment to a nonwoven fabric web of organic fibers to form an electrode. As the entangling treatment, water stream entangling treatment or the entangling treatment using needle punch is adapted. Organic fibers are entangled each other and contact points between fibers are increased to increase the strength as a whole. An active material 1b is filled in a current collector 1a produced by plating nickel on the core body, dried, then rolled with rolls 2a, 2b. Restoring force of the organic fibers is forced out by the active material rolled, and the electrode having high active material filling density is formed.
