Metal Oxide–Carbon Nanocomposites for Electrochemical Storage

Manganese dioxide (MnO2) and biomass-derived carbon-based electroactive composite materials for supercapacitor applications

“…In comparison to pure MOs, the combination of MO with carbon-based nanostructures has demonstrated superior performance in galvanostatic cycling investigations. 103 Recently, MO-carbon composites have attracted considerable attention because of their chemical, physical, electrical, and optical properties as well as many potential applications. 104,105 The composite combines the energy characteristics of pseudocapacitive materials (via fast redox reversible reaction) with cyclic stability and power characteristics of carbon materials (electrostatic fast ion adsorption and desorption at electrode-electrolyte interfaces) and boost cycle life.…”
