Herein, we synthesized 1D bimetallic hydrogen phosphate [CoxNix(HPO4)] nanorods by using a simpleand effective chemical bath deposition method for supercapacitor applications. The preparedCoxNix(HPO4) was analyzed by Fourier transform infrared (FT-IR) spectroscopy and X-ray diffraction(XRD) pattern. The surface morphology was envisaged by scanning electron microscopy (SEM) and transmissionelectron microscopy (TEM) methods. The porous nature and surface area of the materials werecharacterized by nitrogen sorption isotherm and a high specific surface area of 153 m2 g1 was foundto be for Co0.75Ni0.25(HPO4). The Co0.75Ni0.25(HPO4) displays a maximum specific capacity of475 mA h g1 at 1 A g1 in a three-electrode configuration using 3 M KOH as the electrolyte. Co0.75Ni0.25(HPO4) exhibits almost 94.8% of its initial specific capacity over 5000 GCD cycles at 10 Ag1. Furthermore, the fabricated asymmetric supercapacitor (ASC) with Co0.75Ni0.25(HPO4) and activatedcarbon (AC) showed a high specific capacitance of 182.5F g1 at 0.5 A g1. The ASC device delivered amaximum energy density of 64.88 Wh kg1 at a power density of 800 W kg1.

Here, we report a simple strategy to grow NiSe architectures vertically on nickel foam (NF) via facilesolution-based deposition. The as-synthesized NSE7h core-shell nanoplate structure with a mass loadingof 6.4 mg/cm 2 can be delivered a high specific capacitance of 2234.84 Fg 1 at 10 mA cm 2 andoutstanding rate capability compared to that of NO (708.52 Fg 1), NS (968.22 Fg 1), NSE1h (1357.43 Fg 1),and NSE4h (1675.87 Fg 1). The desirable electrochemical performance was mainly attributed to thecomponent’s synergy assuring rich redox reactions, deposition of selenium on the surface of NiOnanotubes, high conductivity, great specific area and furthermore, rapid ion diffusion distance, witheffective transport pathway of electrons and electrolyte ions. The existence of selenium vacancies andversatile synthesis of NiSe architectures would open up a wide range of applications in energy storageand conversion applications including supercapacitors, electrocatalysis, and batteries.
