Recent Advancements in Electrochemical Deposition of Metal‐Based Electrode Materials for Electrochemical Supercapacitors

The Chemical Record, Год журнала: 2022, Номер 22(7)

Опубликована: Март 21, 2022

Abstract The demand for energy storage devices with high and power densities has increased tremendously in this rapidly growing world. Conventional capacitors, fuel cells, lithium‐ion batteries have been used as the long term. However, supercapacitors are one of most promising because their specific capacitance, density, longer cycle life. Recent research focused on synthesizing transition‐metal oxides/hydroxides, carbon materials, conducting polymers supercapacitor electrode materials. performance can be improved by altering electrolytes, current collectors, experimental temperatures, film thickness. Thousands papers already published, reflecting significance elucidating how much demanding such fast‐growing generation. This review aims to illustrate materials loaded various conductive substrates electrochemical deposition employed provide broad knowledge synthetic pathways, which will pave way future research. We also discussed basic parameters involved studies advantages techniques through literature analysis. Finally, trends directions exploring metals/metal composites toward designing constructing viable, high‐class, even newly featured flexible electrodes, systems presented.

Bimetallic Phosphides for Hybrid Supercapacitors

The Journal of Physical Chemistry Letters, Год журнала: 2021, Номер 12(21), С. 5138 - 5149

Опубликована: Май 25, 2021

Supercapacitors (SCs) are considered promising energy storage systems because of their high power output and long-term cycling stability; however, they usually exhibit poor density. The hybrid supercapacitor (HSC) is an emerging concept in which two dissimilar electrodes with different charge mechanisms paired to deliver without sacrificing output. This Perspective highlights the features transition-metal phosphides (TMPs) as positive electrode HSCs. In particular, bimetallic nickel cobalt phosphide (NiCoP) multiple redox sites, excellent electrochemical reversibility, stability discussed. We outline how rational heterostructures, elemental variations, nanocomposite morphologies tune properties NiCoP further sheds light on NiCoP-based composites that help improving overall performance HSCs terms density stability. key scientific challenges perspectives building efficient stable for future applications
