Battery-type electrode materials known for high electrochemical performance are commonly paired with carbon-based materials, which have recently gained attention for their potential application in supercapacitors. These carbon-based materials offer the potential for comprehensive energy storage properties along with excellent cycle life. In this study, a carbon nanofiber (CNF)-based elongated square bipyramid-like manganese tungstate (MnWO4; MnW) composite was synthesized via a simple and cost-effective solid-state reaction followed by an impregnation method. The main objective was to understand the synergistic effects of varying the content of CNF in the reaction on the formation of two different composites (MnW-CNF@L and MnW-CNF@H) and their physicochemical and electrochemical properties were thoroughly examined and compared to those of the MnW. Pure composites have a high crystalline …
