SECONDARY BATTERY AND METHOD OF MANUFACTURING THE SAME

摘要

A secondary battery according to the prevent invention relates to a second battery which includes a laminate of an electrode and a separator. The secondary battery has a chamber shape having no edge. Also, a method of manufacturing the secondary battery according to the prevent invention relates to a method of manufacturing a secondary battery including a laminate of an electrode and a separator. The method includes: a notching step of forming a chamfer shape in the electrode in a notching process; a laminating step of alternately stacking the electrode and the separator; and a separator processing step of allowing the separator to have a chamfer shape corresponding to the chamber shape of the electrode.
