Lithium cell with a cathode comprising a copper compound oxide

摘要

There is provided a lithium cell comprising a negative electrode made of lithium or a lithium containing material, an electrolytic solution based on an organic solvent, and a positive electrode active material which comprises a copper compound oxide and an atomic ratio of a number of lithium atoms (Li) which react with one molecule of the copper compound oxide during discharge of the lithium cell to a number of oxygen atoms (O) contained in one molecule of the copper compound oxide, which ratio is expressed as Li/O, is at least 1.
