ABSTRACT:
The invention provides a lithium secondary cell including an inner electrode body impregnated with a non-aqueous electrolyte, made up of a positive electrode and a negative electrode each made of at least one metallic foil wound or laminated together and collectors to lead out a current from this inner electrode body. The edges of the metallic foil of the positive electrode and/or the negative electrode and predetermined parts of the positive electrode collector and/or negative electrode collector are joined together to lead out a current from the inner electrode body. The edges of the metallic foil, the edges (joint edges) arranged to be joined to the predetermined parts of the positive electrode collector and/or the negative electrode collector and the predetermined parts of the positive electrode collector and/or the negative electrode collector are joined together. The lithium secondary cell has excellent productivity and space-saving capability.
