Title:
ELECTRODE ROLL DRYING METHOD, AND ELECTRODE ROLL DRYING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/053198
Kind Code:
A1
Abstract:
[Problem] To shorten the time for drying an electrode roll. [Solution] A drying device (10) for an electrode roll (20) includes: a drying oven (30) that accommodates an electrode roll in which an electrode base material (21) is wound around a winding core (22); an outer-side heater (40) that heats the electrode roll from the outer side; an axial-side heater (50) that heats the electrode roll from the winding core side; a pressure reducer (60) that lowers the internal pressure of the drying oven; a sensor (70) that detects the temperature of the outermost portion of the electrode roll; and a control unit (80) that controls the operation of the outer-side heater and the like on the basis of the temperature of the outermost portion of the electrode roll as detected by the sensor. The control unit operates the outer-side heater and the axial-side heater so as to heat the electrode roll from both the outer and winding core sides. If the temperature of the outermost portion of the electrode roll reaches a target temperature that is lower than the allowable temperature that is allowed as the upper limit temperature at the outermost portion, the control unit stops the operation of the outer-side heater, operates the pressure reducer so as to reduce the pressure within the drying oven, and heats using the axial-side heater while reducing pressure using the pressure reducer.
