Recent progress of battery grade metal sulfides for hybrid energy storage devices

Abstract

Summary The modern technology‐based hybrid energy storage devices (HESDs) in recent times, due to excelling collective features of secondary batteries (SBs) and supercapacitors, have attained the remarkable attention of scientific community throughout the globe. The metal sulfides and their composites among all electrode materials owing to their viable electrochemical characteristics have been recognized as important contender for hybrid devices. In this regard, our work reports the recently utilized single, binary, and ternary composites of metal sulfides as battery grade electrode material for HESDs. Along with synthesis routes including hydrothermal, electrodeposition, solvothermal, microwave, and sonochemical process. Apart from this, different electrochemical characterizations such as cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and galvanostatic charge discharge (GCD) have been conferred in this review. Furthermore, the electrochemical performance of sulfide‐based HESDs has compared and summarized. The high energy outcomes, current challenges, and future prospects of metal sulfides as electrode material have also been discussed.

Zinc‐ion hybrid supercapacitors: Design strategies, challenges, and perspectives

“…Instead, hybrid supercapacitors (HSCs), which are composed of battery-type electrodes with rich redox reactions and capacitor-type electrodes with fast ionic conductivity, may provide a good solution, because HSCs would combine the benefits of batteries and capacitors to meet the requirements of energy storage systems that require both a high energy density and a high power density. [17][18][19][20][21] The HSCs are classified as alkali metal ion (Li + /Na + / K + ) HSCs [22][23][24][25] or multivalent metal ion (Zn 2+ /Mg 2+ /Ca 2+ / Al 3+ ) [26][27][28] HSCs, based on the different metal ion types. In recent years, extensive investigations on these HSCs have been performed and most were related to lithium-ion HSCs, although a number of issues still existed for lithiumion HSCs in practice.…”

Metal‐Organic‐Framework as Novel Electrode Materials for Hybrid Battery‐Supercapacitor Applications

“…[11,12] In recent years supercapacitors (SCs) catches noticeable attention due to their promising features like high power density and life cycle relative to batteries. [13][14][15][16][17][18][19] Due to the indifferent charge storage mechanisms, supercapacitors can have millions of charge discharge cycles. In batteries, there is a kinetically limited charge rate in contrast supercapacitor has high charge rate than discharge rate as shown in schematic Figure 1.…”
