Abstract
A method of manufacturing a secondary battery includes manufacturing an electrode assembly by winding a first electrode, a second electrode, and a separator together; attaching a tape to cover an outermost edge portion of the electrode assembly; accommodating the electrode assembly in a battery casing having an open end; and removing the tape attached to the electrode assembly from the electrode assembly. The tape includes a first portion attached to the electrode assembly, and a second portion extending from the first portion in a first direction towards the open end of the battery casing. In the removing the tape, the tape is removed by pulling the second portion.
