Nitrogen-Doped Carbon Materials from Nitrogen Rich Precursors (Chicken Feathers) for Supercapacitor Application
Problem Statement
Supercapacitors a class of electrochemical energy devices, have high power density but relatively low energy density in comparison to battery technology. The energy density in supercapacitors depends on specific capacitance of electrode material which largely depends on the physical and chemical characteristics of their electrode materials. In this context, many novel materials with improved energy density already have been synthesized which suffer from some drawbacks of poor conductivity, extraordinary cost and inadequate cycle stability which hinder their practical applications. In commercial supercapacitors (double layer) activated carbon electrodes demonstrate high power density (up to 105 kW/kg) and long cycle life (millions of cycles), whereas they exhibit low energy density. Nitrogen-doped carbon materials (NDCMs) are promising materials where capacitance can be improved by redox functionalities on surface or inside the nano-domains while maintaining high rate capability and long cycle life. Therefore, there is great research potential in the area of designing electrode materials for supercapacitor technology.
