BATTERY MANUFACTURING METHOD AND DEVICE THEREOF

PROBLEM TO BE SOLVED: To simply and easily obtain a battery with an excellent performance.SOLUTION: Mixed powder containing powder of an active material, powder of a conductive material and binder powder is emitted in a coating booth 24 constituting a battery manufacturing device 20 from coating guns 26a, 26b. Thereby, a positive electrode active material layer 2 made of the mixed powder is coated on a strip 22 (collector). A press machine is arranged on a downstream side of the coating booth 24, and temperatures of a first heat roller 62 and a second heat roller 64 constituting the press machine are increased by heating a first heater 66 and a second heater 68 in advance. Accordingly, when the positive electrode active material layer 2 carried from the coating booth 24 is sandwiched between the first heat roller 62 and the second heat roller 64, heat-processing and roll-processing are simultaneously applied to the positive electrode active material layer 2.
