Abstract
A lithium secondary cell includes an inner electrode body impregnated with a non-aqueous electrolyte. The inner electrode body includes a positive electrode and a negative electrode wound or laminated together with a separator inserted therebetween. A cell case contains the inner electrode body and includes an electrode cover sealing the inner electrode body and is provided with cell covers, external terminals and internal terminals. The lithium secondary cell is provided with a unit for cooling the electric current path. The lithium secondary cell is capable of preventing a lowering of performance and extending the service life by preventing heating of the lithium secondary cell and maintaining the cell temperature within an adequate range.
