▎ 摘　　要

NOVELTY - The electrode has a positive electrode active material layer formed on a side part of a current collector. A carbon material layer i.e. graphene layer, is arranged between the current collector and the positive electrode active material layer. The positive electrode active material layer is provided with multiple active material particles. Each active material particle is provided with material particles. A graphene shell layer is formed on a surface of each material particle. Diameter of the carbon material layer is about 1-50 micro meters. USE - Lithium ion battery positive electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a lithium ion battery positive electrode.
