This study introduces a green and scalable method to fabricate a novel electrode and solid-state electrolytes using Date seeds biomass and Phoenix dactylifera (palm tree) waste -derived activated carbon. The Date seeds biomass substrate offers biodegradability, porosity, and mechanical flexibility, while the Date seeds biomass and Phoenix dactylifera (palm tree) activated carbon enhance redox activity and surface area. Electrochemical characterization showed distinct redox peaks and excellent pseudocapacitive behavior. The supercapacitors fabricated with Date seeds had excellent electrochemical performance of specific capacitance 315 F/g. Moreover, This sample exhibited the highest ionic conductivity of 10.6 × 10−3 S cm−1 at 25 °C . This research demonstrates that Date seeds and Phoenix dactylifera (palm tree) activated carbon electrodes and electrolytes are a promising, low-cost, and eco-friendly electrode material for flexible supercapacitor applications, contributing to sustainable energy storage solutions and aligning with global environmental goals. Integrating supercapacitor into  electrical system is a simple and cost-effective way to reduce your electricity bill. By correcting the power factor, stabilizing the voltage, and enabling energy storage, capacitors can make a significant impact on your electricity consumption and costs.Production of electric cars and vehicles that can be charged in 8 minutes using a supercapacitor instead of a lithium battery.
