Abstract
A lithium secondary cell includes an internal electrode body having a positive electrode plate and a negative electrode plate wound and laminated around an external peripheral wall of a hollow cylindrical winding core. The inside of the internal electrode body is impregnated with a nonaqueous electrolyte solution. A cylindrical cell case houses the internal electrode body and has open ends sealed with plate member electrode caps. An external terminal member protrudes onto the surface of the electrode caps to lead current to the outside of the cell case, and an internal terminal member connects with the internal electrode body to take current from the internal electrode body. An elastic body and at least two of the plate member, the external terminal member and the internal terminal member are joined together for construction. An assembly of lithium secondary cells is also disclosed.
