Abstract

In quest of potential electrode material with high redox sites, better wettability, rapid ionic channels and high rate capability here we adopted a soft template method (surfactants). This work investigates the effect of non-ionic and ionic surfactant on microstructure and surface morphology thereby its electrochemical properties in detail. The physiochemical characterization of prepared samples stated that purity of prepared Ni₂P₂O₇ was high and its surface morphology were significantly altered by different templating agents. In particular, Ni₂P₂O₇ without and with surfactants (PEG, PVA, PVP and CTAB) showed a specific capacitance of 120, 95, 126, 128 and 250 F/g at a current density of 2 A/g, respectively. Furthermore, the asymmetric device with NiP_(CTAB) as cathode own an energy density of 20 Wh/kg at a power density of 1550 W/kg and retained 70% of its initial capacitance upto 4500 cycles.
