     The growing demand for high-performance lithium-ion batteries (LIBs) has driven interest in silicon anodes due to their high theoretical capacity compared to conventional graphite anodes. However, silicon suffers from severe volume expansion during lithiation and delithiation, causing structural degradation and poor cycling stability. This study investigates sustainable silicon anodes derived from rice husk, an agricultural waste rich in silica. Rice husk-derived silica was converted into silicon through thermal treatment and magnesiothermic reduction. Characterization using XRD and SEM-EDS confirmed the formation of porous silicon structures, while electrochemical analyses using cyclic voltammetry (CV) and electrochemical impendance spectroscopy (EIS) demonstrated improved charge transfer behaviour and promising potential for sustainable high-performance energy storage applications.
