▎ 摘　　要

An end-face electrochemical exfoliation (EFEE) strategy for scalable graphene preparation is established, which has the confined area and thus guarantees uniform current density at the air-electrolyte interface, different from the traditional electrode set-up. The production of graphene is presented that has excellent yield (similar to 100%) and outstanding conductivity (3.8 x 10(4) S m( 1) with a graphene loading of 0.7 mg cm( 2)). The exfoliation mechanism is also discussed. (C) 2018 Elsevier B.V. All rights reserved.
