ABSTRACT:
The invention provides a new positive electrode active material having increased capacity and a method for operating an electrochemical lithium cell or battery which has the new positive electrode active material composition. The positive electrode comprises first and second lithium-containing active materials which are different from one another. The invention provides the ability to overcome first cycle inefficiency typically observed when using a single lithium-containing metal chalcogenide by adding a small amount of a second lithium-containing metal chalcogenide, preferably lithium copper oxide.
