BIOMENTS · The synergy of Cement and Biomass-derived Carbon composite for Sustainable Energy Storage Solution

Contemporary energy storage technologies, such as batteries and fuel cells, grapple with issues of power density, longevity, and safety. Supercapacitors present a viable alternative with their high-power density, extended cyclic life, wide operational temperature range, and superior safety. The main hurdle for supercapacitors is their moderate energy density, which is vital for storing renewable energy efficiently. Research is honing in on novel materials to boost energy density and synthesis techniques to augment electrochemical performance. With environmental and material availability concerns in mind, the focus has shifted to accessible and eco-friendly materials like biomass and cement. The proposed research aims to develop supercapacitor electrode materials from cement—a construction industry mainstay—and activated carbon from plentiful organic biomass. Cement's inherent poor conductivity and low surface area might limit its electrochemical efficacy, but pairing it with conductive materials could leverage its potential for both building and energy storage. The research will delve into the Cement/AC composite for supercapacitor electrodes and will craft and evaluate a supercapacitor with an apt gel electrolyte for real-world use. The study will experiment with different cement-to-activated carbon ratios and preparation methods to refine the qualities needed for a potent supercapacitor electrode. This research could lead the way in energy storage innovation, enabling rooftop structures to harness and store energy from renewable sources such as solar power.
