COATING METHOD OF ELECTRODE PASTE FOR SECONDARY BATTERY AND COATING/DRYING DEVICE OF ELECTRODE PASTE FOR SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a secondary battery of high productivity with inconvenience in soldering a collector plate avoided without the loss of the mixture or addition of a new process, by restraining the exudation of paste into a non-coated area.

SOLUTION: In continuously coating mixture paste composed of an active material, a binder and a thickener on a hoop-like core material by the use of a paste-discharging nozzle with a slit groove in a width direction, compressed air is sprayed at both ends of a coated area and/or a non-coated part located in the coated area.
