| titleOfInvention | Lithium ion battery cathode material, and preparation method and lithium ion battery thereof |
| abstract | The invention discloses a lithium ion battery cathode material, and a preparation method and a lithium ion battery thereof. The technical problem to be solved is to increase the discharge capacity, the multiplying power, the liquid absorption and the circulation performance of the lithium ion battery. The cathode material disclosed by the invention is a composite material which is composed of a graphite substrate, a mesh carbon nano-tube and/or nano-carbon fibre growing in situ of the graphite substrate, and/or the mesh carbon nano-tube and/or the nano-carbon fibre mixed in the graphite substrate, and a nano columnar structure. The preparation method disclosed by the invention comprises the following steps of: adding a catalyst into the graphite substrate material; putting in a furnace chamber; and introducing carbon source gas at 300-1300 DEG C. Compared with the prior art, the cathode material disclosed by the invention has the advantages of simplicity in process, precision for control and easiness for reproduction; the specific surface area of the cathode material is increased; the conductivity is increased; the discharge capacity is increased by 10-30 mAh/g; the ratio of 10C/1C is more than or equal to 94%; the battery is manufactured from the material in the invention; the use amount of a conductive agent can be reduced; and the cost of the lithium ion battery can be reduced. |
