Carbon-doped lithium manganese oxide and a method of making the same

摘要

Carbon-doped lithium manganese oxides in crystalline powder form can be used as electrode material. The carbon-doped lithium manganese oxide is prepared by a process including the steps of: preparing a first solution of a lithium compound and a manganese compound, said first solution having lithium ions and manganese ions at a mole ratio of 1:2; preparing a solution of polyethylene glycol and adding the polyethylene glycol solution to said first solution to form a second solution and then drying the second solution until a gel is obtained while stirring the second solution; and pre-treating said gel and then heating the pre-treated gel.
