摘要：

The electrochemical behavior of a new cobalt-substituted Li2O-yMnO(2) (y = 4) spinel phase is studied in liquid-electrolyte lithium cells. The insertion electrode material was obtained by reacting the mixed carbonate Co0.14Mn0.86CO3 with LiOH a 380 degrees C. The spinel phase with Li2.13Co0.57Mn3.66O9 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.
