A significant challenge in the realm of asynchronous capacitors is the development of innovative electrode materials with improved electrochemical behaviour and increased cycles. In this article, a new method is proposed for the facile synthesis of bi metal pyrophosphate anchored on polypyrrole (CoNiP2O7/NF@PPy) utilizing the hydrothermal and polymerization procedures. Cobalt nickel pyrophosphate nanoarrays are created, and they are successfully used as an electrode material for supercapacitors. The novelty of this work, a novel electrode of binder free mixed metal pyrophosphate (CoNiP2O7) composited to conducting polymer of polypyrrole is developed. Then, the prepared CoNiP2O7/NF CoNiP2O7/NF@PPy electrodes capacitive and diffusive mechanism discussed by using Trassati method. In electrochemical experiments, the CoNiP2O7/NF@PPy composite showed considerably enhanced specific capacity (1202 mAhg−1), which is much greater than that of pure CoNiP2O7/NF (819 mAhg−1). Additionally, the hybrid supercapacitor (CoNiP2O7/NF@PPy//AC) device manufactured had the highest energy density of 94.6 Wh kg−1. These findings indicate that this composite is a promising option for electrochemical capacitors.

“…Chemical or electrochemical doping can be used to increase the conductivity of PPy. However, many efforts have been made to improve its capacitive properties due to its weaknesses such as low cyclicity, low speed, and short life (15)(16)(17). Recently, transition metal sulphides have attracted great interest as electrode materials for supercapacitors.…”

Industrialization and the increase in the world population increase the need for energy.Supercapacitors are preferred because of their features such as high specific power, long life, environmentalfriendliness, fast charge, and discharge rates. Supercapacitors are divided into two categories as EDLC andpseudo capacitors. Pseudo capacitors use materials that exhibit pseudo capacitance, such as transition metaloxides/sulphides and conductive polymers. Electrochemical studies and synthesis methods of polymerbased metal oxide composites, polyaniline and polypyrrole are examined in detail. Evaluating the variousmethods used in the preparation of supercapacitor electrodes, an idea is presented on the selection ofsuitable materials for electrochemical applications. Conductive polymers have good capacitance behaviorbut low cyclic stability. Transition metal sulfides exhibit electrochemical performance with highcapacitance values and excellent redox reversibility. This study investigates NiS/PPy polymer assupercapacitor electrode material. The NiS structure was synthesized using Na2S and nickel foam. NiS-PPycoating was carried out by electrochemical coating method. Structures were characterized by XRD andSEM, electrochemical studies such as cyclic voltammetry (CV), galvanostatic discharge (GCD) werecarried out. By incorporating NiS into the PPy matrix, the C value was increased from 22.22 to 1404 F g-1
