▎ 摘　　要

NOVELTY - A high energy density slurry comprises 100 pts. wt. positive electrode active material, 0.01-0.1 pt. wt. composite conductive agent, 0.4-3.0 pts. wt. binder and 30-50 pts. wt. solvent. The composite conductive agent contains single-walled carbon nanotubes and graphene in the mass ratio of (0.1-10):1. The single-walled carbon nanotubes have specific surface area of 500-700 m2/g, diameter of 0.7-1.8 nm and length of more than 5 mu m. The graphene has specific surface area of 2000 m2/g or more. USE - High energy density slurry for positive electrodes of batteries (claimed). ADVANTAGE - The high energy density slurry economically provides batteries with high energy density. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the slurry.
