Method and system for drying electrode plate of secondary battery

Abstract

The present invention relates to a method for drying an electrode plate capable of solving an electrode plate overdrying problem and a drying uniformity deterioration problem due to a pressure change by including: a supply air volume setting step of setting an initial supply air volume introduced into a drier to a target air volume or less; an exhaust air volume setting step of setting an initial exhaust air volume to a numerical value corresponding to the initial supply air volume set in the supply air volume setting step; and an air volume adjusting step of increasing a supply air volume and an exhaust air volume from the initial air volumes set in the supply air volume setting step and the exhaust air volume setting step to designated target air volumes for a predetermined time, and a system for drying an electrode plate capable of effectively implementing the same.
