Abstract:
1. An activated positive electrode for a non-aqueous lithium cell prepared by combining: (a) a first component containing one or more metal cation- and Li (b) a second component containing one or more charged or partially-charged metal cation-containing electrode materials selected from the group consisting of a charged or partially charged lithium metal oxide, a charged or partially charged metal phosphate, and a charged or partially charged metal sulfate, which can accommodate lithium within their structure during the charging and discharging of the electrode when included in an electrochemical cell, to form a precursor material; fabricating an electrode from the precursor material, and subsequently electrochemically activating the electrode by applying a sufficiently high potential to the electrode in an electrochemical cell also including a negative electrode and a non-aqueous electrolyte to remove Li with the proviso that at least one of the first and second components does not contain manganese.
