Title:
METHOD FOR DRYING ELECTRODE COATING FILM OF BATTERY AND DRYING FURNACE
Document Type and Number:
WIPO Patent Application WO/2014/103786
Kind Code:
A1
Abstract:
A method according to the present invention comprises drying a coating film such that there is a constant coating film temperature period during which the temperature of the coating film is constant and such that there are at least two peaks of evaporation speed of a solvent of the coating film during the constant coating film temperature period, thereby providing a uniform distribution of binder in the thickness direction of the dried coating film, that is, the electrode. Further, since the coating film is dried using an infrared heater and hot air from a blower, it is relatively easy to carry out drying such that there is a constant coating film temperature period and at least two peaks of evaporation speed of the solvent.
