摘要： PROBLEM TO BE SOLVED: To provide an electrode for a battery having a desired thickness and a desired capacity, which can prevent deterioration of battery performance accompanying charging and discharging, and to provide a method of manufacturing the same.
SOLUTION: The method of manufacturing the electrode for a battery comprises a process for filling up with an active material an electrode base plate which is made by covering textile surfaces of textile fabric or nonwoven with a metallic layer, and next carrying out its press forming in order to shape the electrode. The press forming is carried out using the electrode base plate having a thickness less than 2.0t where t is a thickness of the electrode that has been subjected to the press forming. By specifying a rate of compressing the electrode base plate that has been filled up with the active material, the thickness of the electrode base plate can be enough to be filled up with a sufficient quantity of the active material and the active material filling up the electrode base plate hardly separates from the electrode base plate.
