LICOXMN2-XO4 AS POSITIVE ELECTRODE MATERIAL FOR 5V LITHIUM SECONDARY BATTERIES |
| 摘要 |
PURPOSE: A lithium-cobalt-manganese compound for anode material of rechargeable lithium battery is provided for achieving structural stability to reduce capacity decrease due to repeated recycling and to apply at high voltage when it used in the production of 5V grade lithium battery. CONSTITUTION: The lithium-cobalt-manganese compound (LiCoxMn2-xO4, wherein 0<x≤ 0.5) as anode material of lithium battery is produced by equalizing the amount of one of the lithium oxide selected from LiOH, LiCO3 or LiNO4, (MnO2) and cobalt oxide(Co3O4) and mixing them; heating the powdered mixture at 800-850 deg.C. for 18-20 hours; and slowly cooling the resulting material. The obtained compound is preferably used in the production of lithium battery activating at 5V or more voltage. The 5V grade lithium battery comprises the lithium-cobalt-manganese compound as anode, and lithium metal or its carbonic compound or other compound as anode material and further includes liquid electrolyte or polymer electrolyte. |
