Non-aqueous secondary cell. |
摘要 |
A rechargeable non-aqueous secondary cell comprising a negative electrode (1); a positive electrode (7) comprising a lithium-including manganese oxide as an active material, the lithium-including manganese oxide having a specific surface area measured by the BET method of 9.0m<2>/g to 67.5m<2>/g; and a separator (8) interposed between the positive and the negative electrodes and impregnated with a non-aqueous electrolyte. A rechargeable non-aqueous secondary cell comprising a negative electrode; a positive electrode comprising a lithium-including manganese oxide as an active material, grain sizes of which are substantially 20 mu m or less when observed by a scanning electron microscope; and a separator interposed between the positive and said negative electrodes. |
