METHOD FOR DEAERATING SECONDARY BATTERY USING CENTRIFUGAL FORCE
摘要
Disclosed is a method for manufacturing a battery cell including an electrode assembly and electrolyte provided in a battery case made of a laminate sheet having a resin layer and a metal layer, which includes: (a) mounting the electrode assembly in the battery case and sealing the periphery of the battery case except for one end part thereof through thermal fusion; (b) introducing the electrolyte through the unsealed end part and sealing the end via thermal fusion; (c) charging-discharging the battery cell to activate the same; (d) transferring gas generated during activation and excess electrolyte to the foregoing end part of the battery cell by centrifugal force; and (e) removing the gas and excess electrolyte from the end part.
