“…The charge/discharge speed of the lithium-ion batteries is mainly controlled via the electrochemical reaction speed and the ion diffusion speed, and the cycling stability is related to the volume changes before and after charge/discharge. It has been both theoretically and experimentally proved that nanostructures could solve these problems [4,6,7,[42][43][44]. This is because the high surface area of nanostructures offers plentiful reaction sites for the electrochemical reactions, and the diffusion paths of charge carriers (or ions) could also be significantly shortened by nanoscale electrode materials.…”

“…This excellent performance is attributed to the good conductivity, large surface area, and stable structure of such micro-nanostructures, which could be explored as promising anode materials for lithium-ion batteries [6]. Doping graphene with nitrogen, boron, phosphorus, or their composites is an effective way to increase the specific energy storage capacity and rate performance, both of which are critically important in designing effective energy storage systems for large-scale applications, including renewable energy [7].…”

Facile synthesis of heteroatom doped graphene nanosheets is one of the recent trends in the development of energy storage materials like supercapacitors. Phosphorus doped graphene sheets (P-GNS) have been prepared using electrochemical method (EC), which is the most emerging technique for large scale synthesis. X-ray diffraction studies of as-electrochemically phosphorus doped graphene nanosheets (EC-P-GNS) synthesized show a shift towards lower 2h values due to functionalized graphene sheets. Scanning electron microscopy analysis of EC-P-GNS shows folded and twisted type graphene nanosheets and the average sheet thickness was measured to be 40 nm. High resolution-transmission electron microscopy depth profile confirms the presence of few layer transparent graphene with twisted type sheets. Fourier transform-infra red analysis of EC-P-GNS confirms the presence of functional groups in the doped graphene sheets. X-ray photoelectron microscopy analysis of EC-P-GNS shows 0.68 % phosphorus atomic doping which confirms the P-doping in graphene nanosheets. The electrochemical performance was analyzed using EC-P-GNS and shows good cycle performance compared to graphite. The electrochemical charge/discharge curves of EC-P-GNS give a high specific capacitance (Csp) of 290 F g -1 along with high energy density 43.75 Wh kg -1 . Based on the above merits including higher Csp, we hope that our EC-P-GNS would be a promising material for super capacitors. Further, the prepared single pot electrochemical anodic erosion strategy provides easy scale up for all heteroatoms doped graphene nanosheets synthesis.

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.
