Dual heteroatom doping of graphene is currently presumed as more promising for energy storage applications. In addition, the development of energy density with multiple redox additives is paying special attention. Here, we report the fabrication of B, P dual‐doped graphene in three various weight combinations. The formation and the quantity of the prepared samples were investigated by XRD, FT‐IR, EDAX and XPS. The B, P dual doped graphene derived from the weight ratio of boron and phosphorus dopant in 1:3 has achieved an enriched gravimetric capacitance of 360 F g‐1 at 1 A g‐1 (1 M H2SO4) and greater than RGO (151 F g‐1). The energy density of the fabricated symmetric supercapacitor cell is found to be 50 Wh kg‐1 in triple redox additives in 1 M H2SO4 solution which is greater than KI (33 Wh Kg‐1) and 1 M H2SO4 alone (5 Wh Kg‐1) at 2 A g‐1. Also, the same cell delivered an increased stability of 99.7% of capacitance retained from its initial value after 7000 charge‐discharge cycles at 5 A g‐1.

Tin disulfide (SnS2) is a prominent candidate in the class of transition metal dichalcogenides (TMD), whose multiple electrical and electrochemical applications have recently steered much attention to energy storage devices like batteries and supercapacitors. Previous studies on the material came under the efforts to improve its applications by doping, creating composites, and other heterogeneous structures, which are complicated and less economical. Thus, pristine SnS2, utilizing its morphological features in conjunction with a suitable synthesis method, was investigated to improve efficiency and reduce cost without confusing processes or structural iterations. In this work, SnS2 is synthesized in its bare form using the hydrothermal method to investigate its potential supercapacitor application. The synthesis route followed a cost‐efficient and simple protocol, and the material shows a porous morphology favoring electrode–electrolyte interaction desirable for supercapacitors. A comprehensive study on the structural, morphological, and surface features done by XRD, FESEM, EDX, XPS, and nitrogen adsorption–desorption analysis confirmed the formation of SnS2 and interior structure. Supercapacitor analysis by CV, GCD, EIS, and cyclic stability tests reveal an intermittent energy storage mechanism, with a capacitance of 109.6 F g−1 at 1 A g−1 and high cyclic retention of 106% at 5 A g−1 after 7000 cycles.
