PROBLEM TO BE SOLVED: To provide an electrode of increased filling density of an active material and raised discharge capacitance without limiting a roll diameter or roll appearance in a production of a battery electrode including a process for forming an electrode by coating and drying a paste containing a powder active material and a binder on a collector to form an electrode precursor and by rolling the electrode precursor. SOLUTION: In this manufacturing method rolling is conducted by different speeds which peripheral velocities of relative rolls vary each other. The value of the different speed ratio of a roll having a smaller peripheral velocity to a roll having a larger peripheral velocity is preferably 2 or under. By conducting different speed rolling which the peripheral velocities of the relative rolls are equal after different speed rolling, high density and high capacitance are further possible. |
