Beschreibung
Zusammenfassung:	A process for preparing a stable Group VIII Period 4 element (iron, cobalt, or nickel) "B" site and chlorine "O" site modified lithium manganese-based AB2O4 spinel cathode material is provided. The general formula of the "B" and "O" site modified lithium manganese-based AB2O4 spinel is LixMn2-yMyO4-z(Clz) where M is Fe, Co or Ni. In addition, a Group VIII Period 4 element (iron, cobalt, or nickel) "B" site and chlorine "O" site modified lithium manganese-based AB2O4 spinel cathode material is provided. Furthermore, a lithium or lithium ion rechargeable electrochemical cell is provided, incorporating the Group VIII Period 4 element (iron, cobalt, or nickel) "B" site and chlorine "O" site modified lithium manganese-based AB2O4 spinel cathode material in a positive electrode.
