This study explores the use of the hyperaccumulator Dracaena trifasciata (snake plant) grown in manipulated soil (with Nickel) to explore a cost-effective, sustainable phytoremediation technique for synthesizing high-performance biocarbon electrode material. The synthesized Nickel-Biochar (Ni-Biochar) is treated with acid to enhance its processability and is then combined with an optimal amount of Polyaniline (PANI) to improve charge conductivity. The Ni-Biochar/PANI electrode demonstrates excellent electrochemical performance, with a specific capacitance of 638 F g?1 at 0.5 A g?1 in a three-electrode cell and notable stability, retaining 92 % of its capacity after 10,000 cycles. Additionally, the asymmetric supercapacitor made with Ni-Biochar/PANI achieves a specific capacitance of 163 F g?1 in a 3 M KOH solution. The Ragone plot for this device reveals an energy density of 57 Whkg?1 and a power density of 1259 W kg?1. The device also shows outstanding long-term cyclic stability, retaining 90 % of its capacity after 5000 charge-discharge cycles. This high level of performance underscores the potential of utilizing plants as green carbon sources, which can be combined with various metal oxides and conducting polymers to produce hybrid nanomaterials, making them highly promising for sustainable supercapacitor electrode applications. 2025 Elsevier Ltd Subject The topic of the resource Biochar; Phytoremediation; Polymerisation; Supercapacitor Publisher An entity responsible for making the resource available Elsevier Ltd Relation A related resource ISSN: 2352152X; Language A language of the resource English Type The nature or genre of the resource Article Rights Information about rights held in and over the resource All Open Access; Hybrid Gold Open Access Format The file format, physical medium, or dimensions of the resource online
