SECONDARY BATTERY AND METHOD OF MANUFACTURING THE SECONDARY BATTERY

摘要

A secondary battery and a method of manufacturing the secondary battery. A secondary battery includes an electrode assembly formed through winding a positive electrode plate including a positive electrode non-coating portion, a negative electrode plate including a negative electrode non-coating portion, and a separator between the positive and negative electrode plates. A part of the positive electrode non-coating portion and a part of the negative electrode non-coating portion are removed to form a positive electrode tab and a negative electrode tab at first and second ends, respectively, of the electrode assembly.
