“…Initially, the decomposition of water that had been absorbed and volatile pollutants in the sample resulted in a modest weight loss. Following that, significant weight loss occurred in the range of temperatures of 300–500 °C, and was ascribed to the breakdown of organic compounds such as thiourea and polyvinylidene fluoride [ 48 ]. In addition, the breakdown of MgSO 4 aids in weight loss.…”

Electrolytes are one of the most influential aspects determining the efficiency of electrochemical supercapacitors. Therefore, in this paper, we investigate the effect of introducing co-solvents of ester into ethylene carbonate (EC). The use of ester co-solvents in ethylene carbonate (EC) as an electrolyte for supercapacitors improves conductivity, electrochemical properties, and stability, allowing greater energy storage capacity and increased device durability. We synthesized extremely thin nanosheets of niobium silver sulfide using a hydrothermal process and mixed them with magnesium sulfate in different wt% ratios to produce Mg(NbAgS)x)(SO4)y. The synergistic effect of MgSO4 and NbS2 increased the storage capacity and energy density of the supercapattery. Multivalent ion storage in Mg(NbAgS)x(SO4)y enables the storage of a number of ions. The Mg(NbAgS)x)(SO4)y was directly deposited on a nickel foam substrate using a simple and innovative electrodeposition approach. The synthesized silver Mg(NbAgS)x)(SO4)y provided a maximum specific capacity of 2087 C/g at 2.0 A/g current density because of its substantial electrochemically active surface area and linked nanosheet channels which aid in ion transportation. The supercapattery was designed with Mg(NbAgS)x)(SO4)y and activated carbon (AC) achieved a high energy density of 79 Wh/kg in addition to its high power density of 420 W/kg. The supercapattery (Mg(NbAgS)x)(SO4)y//AC) was subjected to 15,000 consecutive cycles. The Coulombic efficiency of the device was 81% after 15,000 consecutive cycles while retaining a 78% capacity retention. This study reveals that the use of this novel electrode material (Mg(NbAgS)x(SO4)y) in ester-based electrolytes has great potential in supercapattery applications.

Nitrogen and Sulfur Incorporation into Graphene Oxide by Mechanical Process

et al. 2021

View full text Add to dashboard Cite

Graphene oxide (GO) is one of the carbon nanomaterials used most in novel applications due to its easy synthesis, easy exfoliation, doping potential performance, and good compatibility in composites. Mechanochemical method is used for GO reduction and doping during ball milling (BM) process. Urea and thiourea molecules are employed as nitrogen (N) and sulfur‐nitrogen (S,N) dopant agents, respectively. The elemental composition of BM‐GO‐urea exhibits 7.7 at% of N, whereas BM‐GO‐thiourea displays 6 at% of S with 5.6 at% of N. Using density functional calculations, urea, and thiourea molecules are covalently joined to the carboxyl functional groups. It is shown that nitrogen doping favors a HOMO energy decrement when the molecules are directly attached to graphene sheets in the absence of carboxyl groups, making it energetically less expensive to share electrons in undoped nanomaterials. In contrast, the urea and thiourea molecules joined to graphene sheets via carboxyl groups with deep HOMO energies and low nitrogen‐doping variations. The results demonstrate the viability of the BM technique for GO reduction and N/S dope‐functionalize. Furthermore, the mechanochemical methodology described is employed in graphite with urea and thiourea molecules to contrast results.
