摘　　要：石墨烯纳米筛材料是当前科技前沿中一种新型二维多孔材料,其平面多孔结构有利于电解质离子的纵向传输,缩短了离子传输路径,有效避免了传统石墨烯材料普遍存在的问题,如π–π堆叠造成活性面积低、纵向传输性能差、离子传输路径长和电解液不易浸润等,在能量存储与转换领域中表现出比传统石墨烯基材料更为优异的性能.本文综述了近几年来各种结构可定制、结构/组分复杂性高、形态可控制、电化学性能增强的石墨烯纳米筛材料的合理设计和合成的研究进展,着重讨论了石墨烯纳米筛的结构设计对能源存储与转换方面的性能影响,期望为高性能能源存储与转换方面进一步的创新工作提供参考.Graphene nanomesh material is a new type of two-dimensional porous material at the cutting edge of science and technology.Its planar porous structure is conducive to the longitudinal transmission of electrolyte ions,which shortens the ion transmission path,and effectively avoids the common problems of traditional graphene materials;for instance,electrolyte is not easy to infiltrate andπ-πstacking causes low active area,poor longitudinal transmission and long ion transmission path.The graphene nanomesh materials show better performance than traditional graphene-based materials in the field of energy storage and conversion.This paper reviews the recent progress in the design and synthesis of various kinds of graphene nanomesh with customizable structure,high complexity of structure/composition,controllable morphology and enhanced electrochemical properties.The influence of the structural design of graphene nanomesh on the performance of energy storage and conversion is emphatically discussed,which may provide some inspiration for the relevant research in this field.
