▎ 摘  要

NOVELTY - A conductive material comprises carbon particles porous zirconium nano-particles distributed in the porous of carbon-containing surface graphene, where the graphene is coated with the carbon porous. USE - Conductive material for lithium ion battery used in portable electronic product, bicycle electric electric, energy storage, etc. Can also be used in battery pack for electric vehicle, hybrid electric vehicle (HEV), plug-in HEV (PHEV), etc. ADVANTAGE - The conductive material has better conductive effect, and is easier to form a conductive path between the conductive materials. It has strong conductivity, so in the secondary battery positive negative electrode, it can reduce the dosage of conductive agent, thus increasing the dosage for the active material of the positive electrode active material, so as to greatly improve secondary battery volume energy density. The conductivity of secondary battery pole piece can be ensured on the basis of reducing the dosage. At the same time, conductive network can be constructed in the pole piece of the secondary batteries from the larger space span, realizing the long-range conductive on the whole electrode. The zirconium nano-particle fills the carbon porous surface reduces the impedance porous the carbon particles, thus improving the performance of the material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation method material. DESCRIPTION OF DRAWING(S) - The drawing shows a scanning electroscope of the conductive material obtained in Example 1.
