“…Graphene-based materials are extensively utilized as electrode materials in conventional solid-state supercapacitors, no one has employed MnO 2 /Graphene/PANI as an electrode material in the form of functionalized conductive ink. This ink is formulated by incorporating MnO 2 and PANI nanoparticles into graphene structures for conductive enhancement, achieved by the addition of vehicle resins and additives [13,14]. This process is utilized for fabricating micro-supercapacitors using state-ofthe-art screen-printing technology, where the functional and conductive ink is formulated by incorporating the optimized nanocomposite, considering the characteristics of individual materials such as porosity, tunable functionalization, and high conductivity [15][16][17].…”

In the world of miniature advancements in technology, a current champion has emerged: the micro supercapacitors. In order to fabricate these micro-supercapacitors, we have developed a promising and user-friendly approach for printing a conductive functional ink containing a ternary composite of manganese dioxide (MnO2) nanoparticles, Graphene, and polyaniline (PANI) as a dopant. Screen-printing technique was employed to fabricate micro-supercapacitors using the nanocomposite conductive ink. The performance of the energy storage device was examined using flexible symmetric and asymmetric, with an aqueous 1M KOH electrolyte. According to this strategy, the characterisation and electrochemical study results revealed that doping PANI into both symmetric and asymmetric devices significantly increased the material's capacitive performance of areal capacitance 167 mFcm-² for MnO2/Graphene/PANI-5 composite (MGP-5) and 292.5 mFcm-² for asymmetric supercapacitor (ASSC) at 5 mVs-1. Furthermore, the asymmetric supercapacitor displayed outstanding cyclic stability, retaining 93.6% of its capacitance after 10000 cycles. This underscores the possibility of incorporating polyaniline (PANI) into MnO2 and graphene matrices as efficient blueprints for the development of superior electrode materials. The improvement represents a significant step forward, opening avenues for the future development of novel devices and their integration into top-of-the-line flexible energy storage systems.
