Abstract
<jats:p>The growing demand for environmentally friendly energy storage materials has sparked interest in biomass-derived activated carbon for supercapacitor electrodes. The study looks at the physicochemical properties of chicken litter as a prelude to biochar manufacturing for supercapacitor applications. Poultry litter samples were characterised using proximal, ultimate and compositional analysis to determine their suitability for carbon material synthesis. The results revealed that poultry litter comprises 43.06% carbon, 6.13% hydro-gen, and 40.68% oxygen, as well as 70.26% volatile matter and 18.51% fixed carbon. The inorganic fraction contained large amounts of calcium (4.12%), potassium (3.42%), and silicon (0.89%), which could influence porosity growth during activation. The higher heating value (16.86 MJ kg⁻¹) implies moderate energy content. Based on these properties, poultry litter shows promise as a low-cost, abundant feedstock for producing porous car-bon materials suitable for supercapacitor electrodes, especially when combined with ap-propriate activation strategies to increase surface area and electrochemical performance.</jats:p>
