Oxidation-exfoliation-reduction method is used for industrial production of high purity and low cost graphene powder (G).As conductive additive in Li-ion power batteries, graphene powder is developed into graphene slurry with ultra-highly dispersed, good stability and processability.Based on excellent electrical conductivity (20000S/m) and two dimensional nanostructure of graphene (2~5 layers),graphene slurry could be dispersed into cathode materials of Li-ion power batteries, forming the conducting 3D network, resulting into increased capacity, the improved rate, good-cyding life, high & low temperature performance and safety performance.
