SEKUNDÄRBATTERIE

摘要

A cell capable of preventing precipitation of lithium on a negative electrode plate in the final stage of a cycle life and achieving a superior cycling performance and high safety and reliability is provided. In a rechargeable secondary cell using a non-aqueous electrolyte, a positive electrode contains an active material and a conductive element, and Ketienblack, a mixture of Ketienblack and flake graphite or a mixture of Ketienblack and acetylene black is employed as such conductive element.
