LITHIUM-SEKUNDÄRBATTERIE

摘要

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 (1A) of the positive electrode and/or the negative electrode and predetermined parts of the positive electrode collector (4A) 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) (15) arranged to be joined to the predetermined parts (5) 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.
