Abstract
A lithium secondary battery includes an internal electrode body including a positive electrode, a negative electrode, a separator, the positive electrode and the negative electrode being wound via the separator so that the positive electrode and the negative electrode are not brought into direct contact with each other, an organic electrolyte, and a battery case containing the internal electrode body. A pipe is used as the battery case. The lithium secondary battery is excellent in reliability and can be produced at low processing costs.
