氧化石墨烯诱导的Ni-Co氢氧化物整体电极的制备及电储能特性

超级电容器作为一种新型储能装置,由于其能量密度、功率密度高和良好的循环稳定性,而在实际工业应用中(新能源汽车、航天航空业、电子通信系统、可穿戴设备等)显示出巨大的潜力。但目前面临的最大挑战是构造柔性、轻薄可变形的储能设备。在本项研究工作中,利用溶剂热法和真空抽滤法开发了一种碳基/层状金属氢氧化物的复合材料。设计将氧化石墨烯(GO)与Ni-Co氢氧化物(LDHs)两者在不同比例下协同配合,构造出无粘结剂和导电剂的整体电极材料,作为高性能电化学储能材料具有一定的研究价值。

Preparation of graphene oxide-induced Ni-Co hydride monolithic electrode and its electrical energy storage characteristics

As a new type of energy storage device,supercapacitors are displayed in practical industrial applications(new energy vehicles,aerospace industry,electronic communication systems,wearable devices,etc.)due to their high energy density,high power density and good cycle stability.Great potential.But the biggest challenge currently facing is to construct flexible,thin and deformable energy storage devices.In this research work,a carbon-based/layered metal hydroxide composite material was developed using solvothermal method and vacuum filtration method.The design combines graphene oxide(GO)and Ni-Co hydroxide(LDHs)in different proportions to construct an overall electrode material without binders and conductive agents.As a high-performance electrochemical energy storage material,it has certain research value.
