Investigation of temperature effect on the electrochemical performance of MoSe2@FeOOH composite.

In this article, we report the investigation of the impact of temperature change on the electrochemical propertiesof the prepared composite of molybdenum diselenide and iron oxyhydroxide. The MoSe2@FeOOH (MSFH) compositewas synthesized via the hydrothermal-assisted chemical blending route. The composite formation was confirmed via X-ray diffraction, FTIR, and Field emission electron microscopy characterization tools. The thermal behavior of the MSFH composite was studied via a differential scanning calorimetry tool. The change in electrochemical behavior with temperature (40 to 80 ℃) of the symmetric cell based on theMSFH composite has been investigated here. The maximum specific capacitance for a cellat 60 ℃ was observed to be around 91 F g−1 (at 100 mV s−1). Hence, the electrochemical resultsindicate the practical use of MSFH-based symmetric cells over a wider range oftemperatures in energy storage applications. [ABSTRACT FROM AUTHOR]
