摘要 |
The present 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 wound or laminated together with a separator inserted in between, an cell case that contains the inner electrode body and an electrode cover that seals the inner electrode body 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 temperature within an adequate range.
