“…MoS 2 ‐GA hybrid electrode has high area capacitance (0.32 F/cm 2 ), good rate performance, and good cycle stability (the capacitance is maintained at 92% at 5000 cycles). Suganya et al 90 prepared electrochemically active composites of zinc vanadate (Zn 3 V 2 O 8 ) and nitrogen‐doped multiwalled carbon nanotubes (N‐MWNCT) by a simple hydrothermal method. The prepared composites have high specific capacitance (403 F/g) and good cycle performance (79% capacitance retention under 5000 cycles).…”

As a type of energy storage device between traditional capacitors and batteries, the supercapacitor has the advantages of energy saving and environmental protection, high power density, fast charging and discharging speed, long cycle life, and so forth. One of the key factors affecting the performance of supercapacitor is the electrode material. Carbon materials, such as carbon nanotube, graphene, activated carbon, and carbon nanocage, are most widely concerned in the application of supercapacitors. The synergistic effect of composites can often obtain excellent results, which is one of the common strategies to increase the electrochemical performance of supercapacitors. To further improve the performance of binary composites, it is a relatively simple method to increase the components as the "bridge" between the two materials to form the ternary composites. The review mainly introduces the current research progress of supercapacitors with pure carbon nanomaterials and multistage carbon nanostructures (composites) as electrodes. The characteristics and application directions of different pure carbon nanomaterials are introduced in detail. Different ways of multilevel structure (material) composite have their own effects on the development of high-performance supercapacitors. We also highlight the recent advances related to these fields and provide our insight into high-energy supercapacitors.

“…According to this table, all the previous devices had inferior capacitances (8–201 F g −1 ) and lower energy densities (1.6–72.1 W h kg −1 ). 36,49–55 The highest previously reported capacitance of 201 F g −1 was reached using a Fe–Co alloy, which is ≈3 times lower in comparison with that for our best CuVO/FNC-SC-sw device. Thus, the devices studied here have the highest value of capacitance/energy-density reported so far in the literature (for SCs based on vanadium oxide or alloy compounds).…”

Exploring different types of materials in triboelectric nanogenerator (TENG) research remains a dynamic and evolving field. This work marks an important milestone in this journey by introducing phosphor material, particularly zinc vanadate (Zn 3 V 2 O 8 , ZVO), into TENG technology for the first time. TENG uses ZVO and silicone films as active triboelectric layers. The fabricated TENG exhibits remarkable performance, producing an output voltage of 515 V and a current of 178 μA, resulting in an impressive power density of 6.9 W/m 2 . Furthermore, we demonstrate the practicality of this innovation by powering 360 series-connected LEDs and electroluminescent devices with a simple hand tap. In addition, the luminescence properties of ZVO are also investigated. This research work opens up possibilities for multifunctional applications, harnessing the potential of phosphor materials for energy harvesting and beyond.
