High-performance supercapacitors based on Ni

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 4,   Pages 1021-1032 doi: 10.1007/s11705-020-2006-x

Abstract: We present a one-step route for the preparation of nickel phosphide/carbon nanotube (Ni P@CNT) nanocomposites for supercapacitor applications using a facile, ultrafast (90 s) microwave-based approach. Ni P nanoparticles could grow uniformly on the surface of CNTs under the optimized reaction conditions, namely, a feeding ratio of 30:50:25 for CNT, Ni(NO ) ·6H O, and red phosphorus and a microwave power of 1000 W for 90 s. Our study demonstrated that the single-step microwave synthesis process for creating metal phosphide nanoparticles was faster and simpler than all the other existing methods. Electrochemical results showed that the specific capacitance of the optimal Ni P@CNT-nanocomposite electrode displayed a high specific capacitance of 854 F·g at 1 A·g and a superior capacitance retention of 84% after 5000 cycles at 10 A·g . Finally, an asymmetric supercapacitor was assembled using the nanocomposite with activated carbon as one electrode (Ni P@CNT//AC), which showed a remarkable energy density of 33.5 W·h·kg and a power density of 387.5 W·kg . This work will pave the way for the microwave synthesis of other transition metal phosphide materials for use in energy storage systems.

Size-controllable synthesis of monodispersed nitrogen-doped carbon nanospheres from polydopamine for high-rate supercapacitors

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 11,   Pages 1788-1800 doi: 10.1007/s11705-023-2326-8

Abstract: Monodispersed nitrogen-doped carbon nanospheres with tunable particle size (100–230 nm) were synthesized via self-polymerization of biochemical dopamine in the presence of hexamethylenetetramine as a buffer and F127 as a size controlling agent. Hexamethylenetetramine can mildly release NH3, which in turn initiates the polymerization reaction of dopamine. The carbon nanospheres obtained exhibited a significant energy storage capability of 265 F·g–1 at 0.5 A·g–1 and high-rate performance of 82% in 6 mol·L–1 KOH (20 A·g–1), which could be attributed to the presence of abundant micro-mesoporous structure, doped nitrogen functional groups and the small particle size. Moreover, the fabricated symmetric supercapacitor device displayed a high stability of 94% after 5000 cycles, revealing the considerable potential of carbon nanospheres as electrode materials for energy storage.

Polyaniline‒polypyrrole nanocomposites using a green and porous wood as support for supercapacitors

Jian LI, Yue JIAO

Frontiers of Agricultural Science and Engineering 2019, Volume 6, Issue 2,   Pages 137-143 doi: 10.15302/J-FASE-2019257

Abstract:

Wood is an ideal type of support material whose porous structure and surface functional groups are beneficial for deposition of various guest substances for different applications. In this paper, wood is employed as a porous support, combined with two kinds of conductive polymers (i.e., polyaniline (PANI) and polypyrrole (PPy)) using an easy and fast liquid polymerization method. Scanning electron microscope observations indicate that the PANI‒PPy complex consists of nanoparticles with a size of ~20 nm. The interactions between oxygen-containing groups in the wood and the nitrogen composition of PANI‒PPy were verified by Fourier transform infrared spectroscopy. The self-supported PANI‒PPy/wood composite is capable of acting as a free-standing supercapacitor electrode, which delivers a high gravimetric specific capacitance of 360 F·g at 0.2 A·g .

Fabricating sustainable lignin-derived porous carbon as electrode for high-performance supercapacitors

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 8,   Pages 1065-1074 doi: 10.1007/s11705-023-2313-0

Abstract: Lignocellulosic biomass such as plants and agricultural waste are ideal to tackle the current energy crisis and energy-related environmental issues. Carbon-rich lignin is abundant in lignocellulosic biomass, whose high-value transformation and utilization has been the most urgent problem to be solved. Herein, we propose a method for the preparation of porous carbon from lignin employing an H3PO4-assisted hydrothermal method. We characterize the as-prepared lignin-derived porous carbon and investigate its potential for energy storage. After assisted hydrothermal treatment followed by carbonization at 800 °C, the lignin-derived porous carbon displays a high specific capacitance (223.6 F·g–1 at 0.1 A·g–1) and excellent cycling ability with good capacitance retention. In this present study, the resultant lignin-derived porous carbon was used as the electrode of a supercapacitor, illustrating yet another potential high-value use for lignin, namely as a candidate for the sustainable fabrication of main supercapacitor components.
