  • SECONDARY BATTERY AND METHOD FOR MANUFACTURING SECONDARY BATTERY
    Publication number: 20230299443
    Abstract: A secondary battery includes an electrode assembly in which electrodes and separators are alternatively stacked to be wound, a battery case in which the electrode assembly and an electrolyte are accommodated, and a fixing tape adhering on an outer surface of the electrode assembly to prevent the electrode assembly from being unwound. The fixing tape is weakened in fixing force for suppressing unwinding when being impregnated in the electrolyte so that the winding of the electrode assembly is substantially released to expand in an initial space between the battery case and the electrode assembly. A method for manufacturing the same is also provided.
