Description
Metal oxides and carbon materials are exceptionally compatible material choices for electrode materials on supercapacitors due to their capacity to provide high pseudocapacitance and superior electrical conductivity. Among metal oxides, MnO2 possesses one of the highest theoretical pseudocapacitances, and birnessite layered polyphorm allows fast charge-discharge electrosorption. This compatibility, in turn, results in heightened specific energy and power, respectively. Nevertheless, the deposition of metal oxides onto various carbon allotropes presents several challenges when it comes to harnessing the full potential of carbon's extensive specific surface area and electrical conductivity. Achieving the optimal metal oxide loading of a particular carbon allotrope surface is a key challenge. With this in mind, we are conducting an investigation into the interactions between carbon nanocomposite materials with functional groups (such as OH, COOH, NH2) and birnessite MnO2. Therefore, we introduce in silico models of carbon nanostructures with the mentioned functional groups and MnO2. Morse potential function calculations results indicate better affinity.
