▎ 摘　　要

NOVELTY - An electrode has alternating multilayered structure comprising a graphene layer and a self-assembled electrode active nanoparticles aggregate layer. USE - Electrode for secondary battery and electrochemical capacitor. ADVANTAGE - The electrode has improved adhesiveness between self-assembled electrode active nanoparticles aggregate layer and collector, and provides secondary battery having favorable charging and discharging characteristics. Fast electron transfer is achieved through the graphene layer, and lithium ions are moved quickly through the empty spaces between the aggregates. The mechanical stability is increased to provide favorable long lasting characteristics.
