Abstract
A method for injecting an electrolyte includes heating a case in which an electrode assembly is accommodated, and injecting an electrolyte into the case after the heating of the case. Here, the heating of the case may include heating the case through high-frequency induction heating using a coil. Also, the coil may have a spiral shape to surround the outside of the case along a longitudinal direction of the case.
