The composite material is LiCoO2 powdered material with surface being coated by conductive glass layer. The method includes steps: (1) mixing the said powdered material with solution capable of generating oxide or conductive glass layer for coating surface of the powdered material; (2) adding solution of organic high molecular material to admixture in step (1) or after step (1); (3) after procedures of de-watering, firing and calcining the admixture so as to obtain coated LiCoO2. The battery includes positive pole made from the disclosed composite material. The organic high molecular material not only disperses material to be coated, but also plays function of binder so that oxide or conductive glass layer can be dispersed in solution evenly and can coat on surface of LiCoO2 powdered material evenly. The invention raises thermal stability and reserves good process performance. |
