NOVELTY - A high concentration and high purity graphite slurry comprises graphene slurry having viscosity of below 10000 cPs. The metal impurity content of slurry is below 100 ppm. The mass content of graphene slurry is 15%. USE - High concentration and high purity graphite slurry used for lithium ion battery cathode material (claimed) and automatic feeding system. ADVANTAGE - The graphite slurry has high purity, high concentration and low viscosity performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of high concentration and high purity graphite slurry, which involves adding anti-back stacking and splitting dispersing additive, dispersant, defoamer and solvent according to the proportion and dispersing; and (2) usage of high concentration and high purity graphite slurry for lithium ion battery cathode material.
