Abstract
Abstract

The expansion of energy demands and population make energy depletion an inevitable reality in the twenty-first century. Over the last few decades, there has been a significant emphasis on developing innovative and high-performing active electrode materials for green energy storage devices through extensive research. The study demonstrated that LiMnPO4, synthesized using a simple chemical method, has the potential to be used as an electrode material in energy storage devices like supercapacitors. Various spectral and analytical studies were performed to analyze and demonstrate the synthesized material. The pseudocapacitance of LiMnPO4 through the use of cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance techniques in an alkaline medium. The LiMnPO4 coated with ZiF-8 as a source of cobalt and carbon to enhance the electrochemical performance of LimnPO4. The specific capacitance of the pure sample was 280 F/g, however, the coating protocol increased the specific capacitance to 350 F/g at 10 mVs-1.
