ABSTRACT:
A lithium secondary battery has an internal electrode body formed by winding a positive electrode and a negative electrode on an outer peripheral wall of a hollow winding core and filled with nonaqueous electrolyte solution, a cylindrical battery case containing this internal electrode body 1 inside with its both ends being open, and electrode caps which each have a battery cap, an internal terminal, and an external terminal, the internal electrode body being sealed by the electrode caps at both open ends of the battery case. At least one of the electrode caps has a pressure release hole in a position corresponding with the center axis of the winding core.
