Energy generation can be clean and sustainable if it is dependent on renewable resources prominently utilized stored efficiently. Recently, biomass-derived carbon polymers have been focused developing less hazardous eco-friendly electrodes for energy storage devices. We boosting the supercapacitor's ability by engineering efficient in this context. The well-known conductive polymer, polyaniline (PANI), deposited nickel foam (NF) used as a positive electrode, while activated derived from jute sticks (JAC) NF negative electrode. asymmetric supercapacitor (ASC) fabricated electrochemical studies found that device has exhibited an density of 24 µWh/cm2 at power 3571 µW/cm2. Furthermore, ASC PANI/NF//KOH//JAC/NF good stability with ~86% capacitance retention even after 1000 cycles. Thus, enhanced performances are congregated depositing PANI boosts electrode's conductivity. Such deposition patterns assured faster ions diffusion, higher surface area, ample electroactive sites better electrolyte interaction. Besides advancing technology, such work also encourages sustainability.
