Abstract: |
This invention relates to a Li ionic battery positive material and its preparation method. Said material contains Li transition metal oxide, carbon nm-tube, black carbon and an adhesive mixed in the quality ratio of 80-90%, 3-10%, 0-8% and 3-10% and mixed to a slurry after dissolved by an organic solvent then to be coated on the Al foil to be rolled and dried in vacuum to get the electrode membrane, which gets the advantages of high capacity, high circulation stability and high charge/discharge multiplying factor. |
