▎ 摘　　要

NOVELTY - A high voltage positive electrode comprises positive electrode current collector and positive electrode slurry layer coated on the surface of the positive electrode current collector. The positive electrode slurry layer comprises 87-98 wt.% positive electrode active material, 1-10 wt.% composite conductive agent comprising 57-79 wt.% cellulose, 20-40 wt.% graphene and 1-3 wt.% aluminum powder composition, and 1-3 wt.% binder. USE - High voltage positive electrode. ADVANTAGE - The positive electrode uses cellulose which has excellent network structure after carbonization, thus effectively improving the migration rate of lithium ions in the electrode material, improving the charge and discharge efficiency of the electrode, reducing the amount of graphene and reducing the cost, and uses positive electrode slurry layer which has excellent electroconductivity and effectively improves large-current charge and discharge. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the positive electrode.
