▎ 摘　　要

NOVELTY - Anode comprises a current collector and a anode active material layer on the current collector, where the anode active material layer comprises anode active material and graphene, the ratio Dv50/D1 of the particle diameter of the anode active material and the sheet diameter of the graphene is 0.45-4.5. USE - The anode is useful in electrochemical device and electronic device (all claimed). ADVANTAGE - The anode has reduced electronic impedance and improved flexibility, and improves problem of brittle fracture under the high voltage and real density.
