PROBLEM TO BE SOLVED: To provide the manufacture of an electrode in which electrode active material layers on both sides of a collector do not exfoliate. SOLUTION: This manufacture of an electrode for a battery is constituted by sequentially applying electrode coating compositions including an electrode active material, a binder, a solvent and acid on both sides of a planar collector, and by respectively forming electrode active material layers on the both sides of the collector. Here, the manufacture has a front surface layer drying process, applying the electrode coating compositions on the surface of the collector, forming a coated layer and drying the coated layer, and a back surface layer drying process of the same kind. The drying processes of the front and the back surface layers include a first drying process performed at a temperature range T1 of 70-90 deg.C and a second drying process performed at a temperature range T2 of 120-200 deg.C, so that the temperature difference (T2-T1) is set to be more than 40 deg.C. |
