“…This agglomeration is caused by the van der Waals interactions taken place in graphene sheets, which recompense the bending energy through inter-sheet adhesion, helping to maintain the composite's stability. The attachment graphene network increases the conductivity of the electrode material, allowing for more effective charge storage and discharge in supercapacitors [29][30][31][32]. In Figure 2c, when NG is doped into TiO 2 -ZnSe composite, the agglomeration is decreased, and the overall surface area of the material is increased.…”

The current study explores the prospective of a nitrogen-doped graphene (NG) incorporated into ZnSe-TiO2 composites via hydrothermal method for supercapacitor electrodes. Structural, morphological, and electronic characterizations are conducted using XRD, SEM, Raman, and UV analyses. The electrochemical study is performed and galvanostatic charge-discharge (GCD) and cyclic voltammetry (CV) are evaluated for the supercapacitor electrode material. Results demonstrate improved performance in the ZnSe-NG-TiO2 composite, indicating its potential for advanced supercapacitors with enhanced efficiency, stability, and power density. Specific capacity calculations and galvanic charge-discharge experiments confirmed the promising electrochemical activity of ZnSe-NG-TiO2, which has a specific capacity of 222 C/g. The negative link among specific capacity and current density demonstrated the composite’s potential for high energy density and high-power density electrochemical devices. Overall, the study shows that composite materials derived from multiple families can synergistically improve electrode characteristics for advanced energy storage applications.

“…Furthermore, when building electrodes or current collectors, this high conductivity might eliminate the need for extra conductive materials and binders, simplifying the manufacturing process and reducing costs. This conductivity enhancement facilitates efficient charge transport within the electrode, leading to improved performance in energy storage devices [ 102 , 103 ]. The high surface area of MXene allows for a higher quantity of active sites available for charging/discharging, resulting in enhanced energy storage capacity.…”

MXene has garnered widespread recognition in the scientific community due to its remarkable properties, including excellent thermal stability, high conductivity, good hydrophilicity and dispersibility, easy processability, tunable surface properties, and admirable flexibility. MXenes have been categorized into different families based on the number of M and X layers in Mn+1Xn, such as M2X, M3X2, M4X3, and, recently, M5X4. Among these families, M2X and M3X2, particularly Ti3C2, have been greatly explored while limited studies have been given to M5X4 MXene synthesis. Meanwhile, studies on the M4X3 MXene family have developed recently, hence, demanding a compilation of evaluated studies. Herein, this review provides a systematic overview of the latest advancements in M4X3 MXenes, focusing on their properties and applications in energy storage devices. The objective of this review is to provide guidance to researchers on fostering M4X3 MXene-based nanomaterials, not only for energy storage devices but also for broader applications.
