Title: Synthesis and electrochemical characterization of a new Li-Co-Mn-O spinel phase for rechargeable lithium batteries

Abstract

The electrochemical behavior of a new cobalt-substituted Li{sub 2}O-yMnO{sub 2} (y = 4) spinel phase is studied in liquid-electrolyte lithium cells. The insertion electrode material was obtained by reacting the mixed carbonate Co{sub 0.14}Mn{sub 0.86}CO{sub 3} with LiOH at 380 C. The spinel phase with Li{sub 2.13}Co{sub 0.57}Mn{sub 3.66}O{sub 9} composition was obtained by this procedure. This material shows an extended cycle life in lithium-anode cells working at room temperature in a 3.3 to 2.3 V potential window. Cell capacity is retained by 80% after 200 cycles.
