“…The Ti 3 C 2 T x /MoS 2 composite in an aqueous LiClO 4 electrolyte demonstrates redox activity within the potential range of −0.5 to 1.5 V. In comparison, the potential window for aqueous electrolyte solutions is typically limited to around 1 V, while for organic-based electrolytes, it is around 3 to 3.5 V . However, the synergistic effect of Ti 3 C 2 T x /MoS 2 extends the potential voltage window, making these electrodes ideal for high-energy-storage device applications.…”

Ti 3 C 2 T x is a 2D layered structure and a promising candidate for use as a working electrode material in electrochemical applications, similar to other 2D structured nanomaterials. Moreover, the surface of the Ti 3 C 2 T x material carries a negative charge and, owing to the presence of surface functional groups, exhibits hydrophilic properties. This is due to the formation of hydrogen bonds between water molecules and T x . A Ti 3 C 2 T x /MoS 2 composite was fabricated by using a hydrothermal approach. The composition of MoS 2 in conjunction with Ti 3 C 2 T x enhances the layered distance due to its synergetic effect. The electrode composition exhibits a significantly higher specific surface area of 34.2 m 2 /g −1 in comparison to that of the Ti 3 C 2 T x electrode. A supercapacitor device based on Ti 3 C 2 T x /MoS 2 is primarily fabricated using a 1 M LiClO 4 aqueous electrolyte. This prepared device achieves a high areal capacitance of 1227.2 F/cm 2 at a scan rate of 5 mVs −1 with 90% capacitance retention over 4000 cycles at a current density of 10 A/g, indicating good energy storage capacity. The enhanced ionic conductivity of the composite electrode is compared to that of pure Ti 3 C 2 T x . This research work presents an improved electrode layered structure for studying the electrochemical performance of Ti 3 C 2 T x and Ti 3 C 2 T x /MoS 2 displays as well as their applications in supercapacitor devices.

“…As usual, metal oxides can be found in combination with CP in nanocomposites for supercapacitor electrodes [ 344 , 345 , 346 , 347 , 348 ]. A recent case corresponding to a study by Chetana et al [ 360 ] shows the synthesis of CoS/MXene/PANI and CoS/MXene/PEDOT ternary compounds using supercritical fluid (SCF). These coin cells showed an improved specific capacitance in CoS/MXene/PEDOT (331.1 F g −1 ) over CoS/MXene/PANI (246 F g −1 ) at 2 A g −1 .…”

Due to the energy requirements for various human activities, and the need for a substantial change in the energy matrix, it is important to research and design new materials that allow the availability of appropriate technologies. In this sense, together with proposals that advocate a reduction in the conversion, storage, and feeding of clean energies, such as fuel cells and electrochemical capacitors energy consumption, there is an approach that is based on the development of better applications for and batteries. An alternative to commonly used inorganic materials is conducting polymers (CP). Strategies based on the formation of composite materials and nanostructures allow outstanding performances in electrochemical energy storage devices such as those mentioned. Particularly, the nanostructuring of CP stands out because, in the last two decades, there has been an important evolution in the design of various types of nanostructures, with a strong focus on their synergistic combination with other types of materials. This bibliographic compilation reviews state of the art in this area, with a special focus on how nanostructured CP would contribute to the search for new materials for the development of energy storage devices, based mainly on the morphology they present and on their versatility to be combined with other materials, which allows notable improvements in aspects such as reduction in ionic diffusion trajectories and electronic transport, optimization of spaces for ion penetration, a greater number of electrochemically active sites and better stability in charge/discharge cycles.

“…However, adding PANI and PDOT to the CoS structure significantly increased the capacity to 246 F g −1 (PANI) and 331.1 F g −1 (PDOT), respectively. The CoS/MXene/PDOT hybrid device showed the highest retention at 97.62% after 10,000 cycles compared to CoS 2 /MXene/PANI (96.24%) 19 In order to create electrode material for solid-state asymmetric supercapacitors (ASC), Adil et al successfully created MXene-FeCu MOF based on porous Ni foam (NF).

MXenes are an emerging class of two-dimensional transition metal carbides and nitrides with metallic conductivity and hydrophilic surfaces. The discovery of MXenes has opened new possibilities for developing advanced hybrid composites for energy storage and conversion applications. This review summarizes recent advances in developing MXene-based hybrid composites, including their synthesis, characterization, and electrochemical performance. The heterostructure of MXenes with nanocarbons, metal oxides, polymers, and other nanomaterials can overcome the limitations of pristine MXenes and lead to enhanced lithium/sodium-ion storage, pseudocapacitive performance, and electrocatalytic activity. Various fabrication techniques have been employed to synthesize MXene composites with controlled nanostructures, morphology, and interfacial properties. Characterization by microscopy, spectroscopy, and electrochemical methods has shed light on structure-property relationships in these materials. As electrode materials, properly designed MXene hybrids have achieved high specific capacity, excellent rate capability, and long-term stability. The review also discusses strategies for further improving MXene composite energy storage performance, as well as emerging applications such as thermoelectrics and photocatalysis. Continued research to understand interfacial effects and optimize MXene heterostructures holds promise for developing next-generation energy storage technologies.
