摘要：

Burning agricultural waste has become a serious environmental concern, creating health problems and contributing to global warming. The Indian government has sought to address this issue through a variety of policies and initiatives aimed at promoting sustainable management practices, such as transforming agro-waste into electricity. Biochar is a carbon-rich substance made from biomass that has been pyrolysied in low-oxygen environment. This article addresses the opportunities and advantages of using new technologies to convert agro-waste into biochar based functional materials with their applications in electrochemical supercapacitor. We have established an electrode on graphite sheet using biochar as an active material and investigated its electrochemical behavior using cyclic voltammetry and galvanostatic charge-discharge. This strategy will help to overcome the challenges of safe trash recycling as well as the usage of fossil fuels.
