In the evolving domain of energy storage technologies, synergy sustainable materials and enhanced performance metrics is crucial. This study focuses on zinc-ion hybrid supercapacitors (ZHSs), distinguished by their impressive power densities. The research meticulously evaluates biomass-derived activated carbon (AC) as an effective electrode material, selecting four distinct biomass sources: jute sticks, olive leaves, mango date leaves. These were chosen due to plentiful availability rich lignocellulosic properties. Among configurations studied, stick derived AC (JC) stood out with its tailored morphology substantial specific surface area 1370 m2/g. design facilitated exceptional rate capabilities efficient ion transport, culminating in remarkable long-term stability. Electrochemical analyses across all revealed a comprehensive profile. JC-based ZHS exhibited capacitance 204 F/g, density 73 Wh/kg, 400 W/kg. comparison, OC-based (olive leaves), MC-based (mango DC-based (date leaves) ZHSs demonstrated capacitances 182, 155, 80 F/g; densities 64, 55, 28 respectively, maintained Interestingly, capacity retention 130% after 20,000 cycles, highlighting resilience consistency. A real-world application was successfully powering toy car solely our developed coin cell, showcasing practicality efficiency technology operational devices. findings underscore potential AC, particularly from developing supercapacitors. With high performance, demonstrates use complying circular economy concepts establishing benchmark for future applications.
