▎ 摘　　要

A Ni(OH)(2)-graphenehybrid with a three dimensional (3D) interconnected graphene network was prepared by a simple one-pot hydrothermal method. The 3D structure constructed of flexible and planar graphene sheets (GS) forms an effective electron transfer network and provides a continuous pore structure for ion transport. Moreover, this structure avoids the aggregation of GS and Ni(OH)(2), resulting in a high utilization rate of Ni(OH)(2) at high contents. This study shows the hybrid has a high rate capability and cyclic stability and exhibits a high specific capacitance of similar to 1 461 F.g(-1) at a scan rate of 5 mV.s(-1) with a Ni(OH)(2) mass loading of similar to 84 mass%.
