一步水热法制备氢氧化镍¯石墨烯复合材料及其电化学性能
Assembly of Ni(OH) 2_graphene hybrids with a high electrochemical performance by a one_pot hydrothermal method
摘要
Abstract
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 capabili¯ ty and cyclic stability and exhibits a high specific capacitance of ~1 461 F·g-1 at a scan rate of 5 mV·s-1 with a Ni(OH)2 mass loading of ~84 mass%.关键词
