Abstract
An electrode roll drying device includes a drying oven housing an electrode roll, an outer-side heater configured to heat the electrode roll, an axial-side heater configured to heat the electrode roll, a pressure reducer configured to reduce internal pressure of the drying oven, a sensor configured to detect a temperature of an outermost portion of the electrode roll, and a control unit configured to control operation of the outer-side heater, the axial-side heater, and the pressure reducer. The control unit is configured to operate the outer-side heater and the axial-side heater to heat the electrode roll from the outer-side and winding core side, and, when the temperature of an outermost portion reaches a target temperature, stop operation of the outer-side heater, operate the pressure reducer to reduce the pressure within the drying oven, and carry out the heating by the axial-side heater and the pressure reduction by the pressure reducer.
