Facile synthesis of electrostatically anchored Nd(OH)3 nanorods onto graphene nanosheets as high capacitance electrode material for supercapacitors

Abstract

Neodymium hydroxide nanorods [Nd(OH)3] are developed by a facile chemical precipitation method without any surfactants/templates under an ambient temperature. The neodymium hydroxide nanorods–graphene [Nd(OH)3/G] nanohybrid is prepared by a simple solvothermal reduction process using Nd(OH)3/GO in the mass ratio of 1:0.5 in dimethylformamide for 7 h. This newer Nd(OH)3/G nanohybrid can be used as an electrode material for supercapacitor, which exhibits a good capacitive behaviour with a specific capacitance of 820 F g-1 at 1 A g-1. It exhibits the capacitance retention of 96% even after 3000 continuous charge-discharge cycles. The excellent electrochemical behaviour is mainly attributed to the synergetic effect of Nd(OH)3 and graphene. The asymmetric supercapacitor (ASC) device is denoted as Nd(OH)3/G||AC and poly(vinylidene fluoride) electrospun membrane soaked in 6 M KOH as the electrolyte as well as a separator. The ASC device is working in an optimized potential window of 1.6 V with an energy density of 40 Wh kg-1. Further ASC device exhibits an excellent capacitance retention of 85.3% with the coulombic efficiency of 97% even after 5000 cycles. This newer hybrid electrode material has an impressive result and can be used as an for asymmetric supercapacitor.
