Facile Cetyl Trimethyl Ammonium Bromide-assisted Hydrothermal Synthesis of Spinel NiCo2O4 Nanoplates as an Electrode Material for Supercapacitor Application Thiruthuvadevaraj Antony Sandosh, Albert Simi, Francisxavier Paul Arokia Doss, Chinnappan Adaikalaraj, and Savariappan Albert Nikson Submitted: 14 June 2020 / Revised: 19 September 2020 / Accepted: 10 October 2020 Ternary NiCo2O4 has paying more attention as a class of potential electrochemical energy storage materials. In the present endeavor, we report spinel NiCo2O4 nanoplates, which were prepared by cetyl trimethyl ammonium bromide (CTAB)-assisted hydrothermal technique followed by proper calcination process. The structural and morphological features were characterized by x-ray diffraction, Fourier transform infrared spectra, scanning electron microscope and high-resolution transmission electron microscopic analyses. The supercapacitive properties of the materials were evaluated using cyclic voltammetric, electrochemical impedance spectroscopy and galvanostatic charge/discharge analysis in 1 M NaOH electrolyte. The freshly prepared NiCo2O4 materials offer the specific capacitance of 329 mA h g21 at a current density of 1 A g21, and it provides superior long-term cyclic stability, which retained 97% of initial capacitance after 2000 continuous CV cycles at a high scan rate of 100 mV s21. These outcomes demonstrate thus prepared spinel NiCo2O4 as a significant electrode material for supercapacitor application. Keywords

1. Introduction Depletion of fossil fuels and global warming are the two significant and unquestionable challenges in this century. In order to attain the imperative requirements of the modern society and reply to promising environmental concerns, it is now important to quickly discover and expand new, ecofriendly and cost-effective energy storage technologies (Ref 17). Battery technology is the generally favored option for energy storage applications in the present years, since its high energy density, high voltage limit and sustainable power supply ability. On the other hand, the short lifetime and safety issues of batteries have mainly restricted their commercial uses (Ref 8). Consequently, the industrial and research communities have paid more attention to develop new alternative energy devices as backup power sources. Supercapacitor is a kind of energy
