“…A supercapacitor has a much higher capacitance value than those of general capacitors [1][2][3][4][5][6]. However, unlike other capacitors, supercapacitors have lower voltage limits, which can compensate the performance gradients between rechargeable batteries and typical electrolytic capacitors [7][8][9][10][11][12][13][14][15][16][17]. A typical capacitor consists of two electrodes, where the gaps are filled with a dielectric material [18].…”

Currently, there is an increasing demand for portable and wearable electronics. This has necessitated the development of stretchable energy storage devices, while simultaneously maintaining performance. Hence, the electrodes and electrolyte materials used in stretchable supercapacitors should be robust under severe mechanical deformation. Polymers are widely used in the fabrication of stretchable supercapacitors. It is not only crucial to choose good polymer candidates with inherent advantages, but it is also important to design suitable polymer materials for both electrodes and electrolytes. This mini-review explains the concept of stretchable supercapacitors, the theoretical background of polymer-based electrodes for supercapacitors, and the fabrication strategies of stretchable electrodes for supercapacitors. Finally, we present the drawbacks and areas that still need to be developed.

“…How to in-situ grow these inorganic active materials on CNT films or papers with high loading mass is still need more efforts. In order to address these issues, researchers have carred out various methods to grow metallic oxides on CNT papers or films, such as chemical bath deposition ( Patil et al, 2018 ; Yusof et al, 2020 ) and electrochemical deposition. ( Chen et al, 2016a ; Sun et al, 2018 ; Yang et al, 2017b ) However, these active materials are still not effectively grown on CNT films with high stability and cost effectiveness.…”

In this work, the Co-Ni basic carbonate nanowires were in-situ grown on carbon nanotube (CNT) network through a facile chemical bath deposition method, which could be further converted into active hydroxide via cyclic voltammetry strategy. A series of carbonate nanowire/nanotube with different Co/Ni ratio revealed the different growth status of the nanowires on CNT network. The nanostructures of the as-synthesized samples were examined via powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) techniques. The Co/Ni ratio of the carbonate largely affected the size of the nanowires, that the low Co/Ni ratio was beneficial for thin nanowire formation and the nanowires loading on CNT network. Subsequently, the electrochemical performance of the Co-Ni basic hydroxides was studied in a three-electrode test system. The nanowires with low Co/Ni ratio 1/2 can form nanowire array on individual CNTs, which exhibited better electrochemical capacitive performance than the composite network with high Co/Ni ratio nanowires after electrochemical activation. The addition of Co enhanced the rate performance of the hydroxide/CNT, especially improved the long cycle stability largely compared to the rate performance of pure Ni converted hydroxide/CNT composite film reported by our previous research. This result is valuable for the design of inorganic electrochemical active composites based on conductive networks for energy conversion/storage applications.
