Abstract

The present invention relates to a method for manufacturing a pouch-type lithium secondary battery with a PCM film for improving low-temperature output, and more specifically, to a method for manufacturing a pouch-type lithium secondary battery with a PCM film for improving low-temperature output that can expect improved output characteristics and lifespan of the battery at ultra-low temperatures by preventing rapid temperature changes through the application of a film containing a phase change material (PCM) encapsulated on the outer surface of an Al pouch of the pouch-type lithium secondary battery.
