Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for injecting an electrolyte, the method comprising: heating a case in which an electrode assembly is accommodated; and injecting an electrolyte into the case after the heating of the case, wherein the heating of the case comprises heating the case through high-frequency induction heating using a coil, wherein the heating of the case comprises raising an internal temperature of the case to a temperature of 40° C. to 50° C. through the high-frequency induction heating, and wherein, in the heating of the case, the case is heated for 5 seconds to 10 seconds. 2. The method of claim 1 , wherein the coil has a spiral shape to surround the outside of the case along a longitudinal direction of the case. 3. The method of claim 2 , wherein the case has a cylindrical shape.
