Method for manufacturing rechargeable battery and apparatus for manufacturing rechargeable battery

A method for manufacturing a rechargeable battery, the method comprising:

• applying an electrode mixture that includes an electrode active material to a substrate that becomes a current collector;
• drying the applied electrode mixture;
• obtaining a specific surface area of the electrode active material before the drying the applied electrode mixture, wherein
• the obtained specific surface area of the electrode active material is referred to as an obtained specific surface area, and
• a specific surface area of the electrode active material in a state in which the electrode mixture applied to the substrate forms an electrode plate is referred to as an electrode plate specific surface area;
• and
• adjusting the electrode plate specific surface area after the drying the applied electrode mixture by setting a drying condition of the electrode mixture in accordance with the obtained specific surface area,
• wherein:
• a drying temperature of the electrode mixture is set as the drying condition, and
• the drying temperature is set to be higher as the obtained specific surface area becomes smaller.
