The high energy yielding supercapattery of PANI/VO2 binary nanocomposite

Year: 2024

Type: article

Abstract: The supercapattery material that is capable of providing high energy density ( E ) similar to that of batteries involving Li-ion containing organic electrolytes is achieved by using an aqueous electrolyte (1 M H 2 SO 4 ). The supercapattery material is the nanocomposite of composition PANI59.32 %: VO 2 40.68 % (PV) and which is synthesized by an insitu one-step method. The PV nanocomposite exhibited a special feature of increase of energy storage with increase in number of charge/discharge cycles at 0.4 V s 1 . The PV exhibited an exceptional durability and robustness up to 16790 cycles at 0.4 V s 1 . At 1 A g 1 , the PV furnished a specific capacity ( Q ) of 623.6 C g 1 , an E of 103.9 W h kg 1 and a power density ( P ) of 1.200 kW kg 1 . In addition, the PV also exhibited an remarkable tolerance to the high applied current load during charging and discharging by withstanding up to 21 A g 1 establishing its high rate capability.
