Due to the increasing demands of clean energy, in view of depletion of natural resources like solid fuels and green house gases, the market has started to look into environment friendly energy storage devices. Over here in our project, we decided to look into the fabrication of supercapacitors with carbon materials as electrodes and their performance. The reasons behind why such devices are not commercialized yet is because that such devices often have poor cyclic consistency in terms of their voltage value, charge leaking rate and reduced mass transport capability due to difficulties in fabrication ideal matrix layer. However, due to the rising awareness to be environmental friendly, our project focus on developing energy storage devices using textiles or paper instead of polymeric or metallic substrates. As papers are widely available and it is an renewable resources. This could be done by introducing conductive nano particles onto the paper substrates using Chinese ink for dispersion of the nano particles. The papers used as substrates are coated with polymer to change the paper which is an insulator by default into a conductive material. The quality of the end product is categorized by the resistivity that it exhibits.
