MXene-based nanomaterials are emerging candidates for energy storage applications due to their metallic conductivity, large surface area, and facile redox activity. The sheet restacking tendency and oxidation significantly reduce their application in different industries. This study reported a facile hydrothermal synthesis of a tungsten disulfide (WS2)-decorated Ti3C2T x /functionalized-boron nitride (BN) nanohybrid as a cathode for all-solid-state flexible asymmetric supercapacitors. The MXene/functionalized BN heterostructure showed an increased surface area by reducing the sheet restacking. On the other hand, incorporation of WS2 over the MXene/functionalized BN sheets led to the addition of redox-active centers. The loading of WS2 over MXene/functionalized BN was varied to obtain an optimum electrode that delivered a specific capacitance of 1318 F g–1 at 1 A g–1 in 1 M KOH. An all-solid-state flexible asymmetric supercapacitor was assembled using PVA–KOH–KI gel electrolyte where KI functioned as a redox additive to increase the supercapacitor’s performance. The assembled device achieved an excellent specific capacitance of 140 F g–1 and a good energy density of 19.4 Wh kg–1 at 1 A g–1 with 84% capacitance retention after 10,000 cycles. Additionally, the assembled devices were able to brightly glow a light-emitting diode (LED), indicating their potential practical applicability in future portable electronics.

Developing a solid organic emitter based on an oxazaborinine complex with improved photophysical characteristics has become essential to fulfilling the rising need for optical and electrochemical technology. Two oxazaborinine complexes (TNB (a tri-naphthalene boron complex) and DNB (a di-naphthalene boron complex)) decorated with naphthalene and triphenylamine have been developed, which show emission in the red light region in the solid phase. Their effectiveness as asymmetric supercapacitor electrodes in aqueous electrolytes is also being studied. Polynapthaldimine-substituted DNI (di-naphthalene imine) and TNI (tri-naphthalene imine) have been initially synthesized and converted to a N,O-linked boron complex. TNB in solids (λem 660 nm) and the polydimethylsiloxane (PDMS) composite (λem 632 nm) emit pure red light. The optimized structure has been generated, and the HOMO–LUMO energy was calculated with the help of density functional theory (DFT). Due to the higher conjugation effect and lower HOMO–LUMO energy difference, TNB could be used as a supercapacitor electrode. In a three-electrode configuration, TNB has a maximum specific capacitance of 896.25 F/g. Furthermore, an asymmetric supercapacitor device (ASC) was fabricated in an aqueous electrolyte using TNB as a positive electrode having a high specific capacitance of 155 F/g. Even in an aqueous electrolyte, the ASC device reached the operating potential window of 0 to 1.4 V with an enhanced energy density of 42.19 W h/kg and ∼96% cyclic stability after 10 000 cycles. The reported oxazaborinine complex and its electrochemical efficiency in aqueous electrolytes make it ideal for supercapacitor applications and directly impact the development of advanced electrodes for next-generation supercapacitors.

By adjusting the ratio of MXene to CoS 2 /CuCo 2 S 4 , the electrochemical efficiency of the hybrid nanocomposite electrode was significantly enhanced [ 89 ]. By adjusting the reaction temperature during hydrothermal synthesis, precise control of the lateral particle size of MQDs can be achieved, and large-scale production can be achieved.…”
