MANUFACTURE OF ELECTRODE FOR SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a secondary battery having no problem in gas generation while charging, has a high utilization efficiency of an active material, and has superior charging and discharging characteristics by manufacturing an electrode having a high and even binding property between the active material and a current collector and having a sppcified filling quantity of the active material. SOLUTION: An active material mixture is provided by mixing an electrode active material and an additive of an binding agent to form a preparatory molding body 3 by integrating this active material mixture and a current collector. After compressing the preparatory molding body 3 until its porosity is 30% or less, an electrode molding body is formed by applying an isotropic pressure to the preparatory molding body 3 in an electrode molding process.
