“…The absence of a semicircular region on the high-frequency side indicates a very small charge transfer resistance. [88] This optimized performance of 10C MX is in line with the increased interlayer spacing observed from XRD, enhanced stability, and graphitization observed from the Raman spectrum and the lower series resistance observed from the Nyquist plot.…”

Flexible and binder‐free carbon dot/titanium carbide (CD/Ti3C2Tx) MXene electrode for supercapacitor is fabricated at commercial scale mass loading. The decline in specific gravimetric capacitance due to high mass loading is compensated by the synergistic enhancement in properties of the prepared CD/ Ti3C2Tx hybrid. The optimized hybrid electrode gives a specific gravimetric capacitance of 373 F/g at a current density of 1 A/g. The symmetric supercapacitor developed using the electrode had a specific gravimetric capacitance of 50 F/g, energy density of 4.4 Wh/kg, and power density of 66.6 W/kg at a current density of 1 A/g. The device retains 90.8% capacitance after 5000 cycles when operated at a current density of 1 A/g. Raman spectroscopy analysis provides an evaluation of the evolution of the electrochemical performance of the hybrid with the CD concentration. The work will open up new avenues in textile‐based supercapacitor technology for wearable electronics applications utilizing environment‐benign techniques.This article is protected by copyright.

MXenes, a group of two‐dimensional (2D) metal carbides and nitrides, have emerged as promising electrode materials for supercapacitors. This is primarily attributed to their inherent metal‐like electrical conductivity, layered structure, surface redox reactivity, and superior pseudocapacitance through surface functional groups. Owing to its promising features, this material suffers from low mechanical strength, restacking, and unprecedented oxidation. As a result, balancing the electrochemical performance becomes challenging, eventually impeding its potential applications in lightweight, flexible supercapacitor applications. Recent strategies are centered on lighter and more stable filler materials to tackle these issues. Among these, cellulose is considered one of the most effective renewable materials because of its biocompatibility, thermal stability, high surface area, and mechanical reinforcement. Moreover, nanocellulose is capable of hosting other functional materials on its reactive surfaces, ensuring better ion accessibility, and can be used as an electrolyte separator membrane. This review paper aims to provide a comprehensive overview of recent advances in the fabrication strategy, deterministic parameters for capacitive energy‐storage devices, electrochemical behavior, and the performance of MXene/cellulose‐based electrodes in its three‐dimensional aspect (1D, 2D and 3D) for supercapacitor application. Lastly, this review will outline the challenges and prospects of MXene/cellulose‐based composite electrodes in real‐life supercapacitor applications.

“…At present, lots of literature have proved that the carbon-based materials and pseudocapacitance materials have very excellent capacitive properties as the electrode materials for SCs, such as MOF-derived nanoporous carbons, , graphene, MXene, , RuO 2 , MnO 2 , and conducting polymers . Since the energy storage of those electrode materials mainly was carried out at or near the surface of the active material, there is a certain limit for the improvement of energy density.…”

Cobalt–manganese oxide is a promising electrode material for supercapacitors due to its high theoretical capacity. However, poor electrical conductivity and structural stability limit the energy storage capacity of the Co–Mn oxide material. Herein, an ultraviolet (UV) light radiation strategy is proposed to prepare nitrogen-doped Co–Mn mixed oxide nanoarrays with enhanced electrochemical energy storage for supercapacitors. Co–Mn mixed oxide nanoarrays were first prepared by the hydrothermal method and then irradiated by a UV lamp to induce nitrogen doping. Because of the nanowire array architecture and UV-induced nitrogen doping, the obtained N-doped Co–Mn oxide shows a boosted charge storage performance with specific capacity of 2534 F g–1 (6.28 F cm–2) at 1 mA cm–2 and improved cyclic stability. Even without nitrogen doping, Co–Mn mixed oxide irradiated by UV light still has a high specific capacity of 1940 F g–1 at 1 mA cm–2 and good rate performance (1267 F g–1 at 60 mA cm–2), which is better than that of the Co–Mn mixed oxide sample prepared by conventional resistance furnace heat treatment. Furthermore, a high specific energy of 31.5 W h kg–1 is obtained for the hybrid supercapacitor device assembled by N-doped Co–Mn mixed oxide and N-doped graphene. These remarkable electrochemical performances suggest that the UV radiation method can effectively enhance the electrochemical properties of transition metal oxide materials. This work also provides an alternative to conventional thermal treatment in preparing high-performance electrode materials.
