高性能镍钴磷化物的制备及其在超级电容器中的应用
Preparation of high-performance nickel cobalt phosphide and its application in supercapacitors
摘要
Abstract
Metal phosphide,as an emerging material for supercapacitors,has attracted more and more attention.In this paper,nickel-cobalt sulfide was obtained by hydrothermal method with carbon cloth(CC)as the substrate and nickel chloride and cobalt nitrate as the raw materials.Then nickel-cobalt phosphide(Ni1/2Co1/2P/CC)was finally obtained by low-temperature phosphating method with sodium hypophosphate as raw materials.Electrochemical tests were performed,and the results show that the specific capacitance of Ni1/2Co1/2P/CC is up to 0.87 F/cm2 at the current density of 2 mA/cm2.After 2000 cycles of charge and discharge at 30 A/cm2,the capacitance retention is 80.22%.In addition,with the Ni1/2Co1/2P/CC as positive electrode and the activated carbon(AC)as negative electrode,the asymmetric supercapacitor(Ni1/2Co1/2P/CC∥AC/NF)exhibits a high energy density of 0.25 mWh/cm3 at the power density of 104.99 mW/cm3.关键词
