Supercapacitors are attracting great attention because of their fast charging-discharging ability as well as their high power density. The current research in this area focuses mainly on exploring novel low-cost electrode materials with higher energy and power densities. In this work, thin-film electrochemical capacitors were fabricated using layers of self-synthesized cadmium sulfide quantum dots and organometallic halide perovskite materials as active electrodes. Organometallic halide perovskites exhibit interesting ionic responses as well as extraordinary electronic properties. These properties are exploited in fabricating the electrochemical capacitors, and the devices showed excellent cycling ability with stable capacitance outputs beyond 4000 cycles. Impedance spectroscopy measurements revealed that perovskites do not only serve as active electrodes but also as solid electrolytes, thereby enhancing the capacitance of the devices and hence the energy densities. The layers provide high surface areas for electrolytes to access the electrode materials; reasonably low charge transfer resistance and small relaxation time were also observed. This work opens new opportunities for developing thin-film supercapacitors using low-cost electrode materials and employing a facile, inexpensive solution-process coating.

“…In other words, there are active electrochemical redox reactions on the electrode materials during the charging and discharging processes of FS. Generally, these two types of supercapacitors require electrode materials to possess large surface area, porosity and high conductivity to achieve large capacitance . Therefore, researchers have been trying to develop some new kinds of materials as electrode materials for supercapacitors.…”

Covalent Organic Frameworks: A New Class of Porous Organic Frameworks for Supercapacitor Electrodes

et al. 2019

View full text Add to dashboard Cite

Covalent organic frameworks (COFs) are a new class of porous organic materials, which are constructed with periodic organic units comprised entirely of light elements (typically C, H, O, N and B) and linked by strong covalent bonds. COFs have been applied in extensive fields, owing to their extraordinary properties in areas such as gas storage and separation, heterogeneous catalysis, sensors, semiconductors, drug delivery, and photoconduction. In particular, the ordered micropore or mesopore structures, high surface areas, and designable structures have enabled COFs to become new candidates for supercapacitor electrode materials. This Minireview focuses on the major progress of COFs as electrode materials for supercapacitors.

“…Therefore, to construct SC electrodes, conducting polymers, carbon allotropes, and transition metal oxides/hydroxides are generally chosen because of their high theoretical specific capacitance [17][18][19][20][21][22][23]. On the other hand, the materials have their advantage and disadvantages.…”

Development of Novel and Ultra-High-Performance Supercapacitor Based on a Four Layered Unique Structure

et al. 2018

View full text Add to dashboard Cite

This paper presents an electrode with a core/shell geometry and a unique four-layered porous wrinkled surface for pseudocapacitive supercapacitor applications. To design the electrode, Ni foam was used as a substrate, where the harmonious features of four constituents, ZnO (Z), NiS (N), PEDOT:PSS (P), and MnO 2 (M) improved the supercapacitor electrochemical performance by mitigating the drawbacks of each other component. Cyclic voltammetry and galvanostatic charge discharge measurements confirmed that the ZNPM hybrid electrode exhibited excellent capacitive properties in 2 M KOH compared to the ZNP, ZN, and solely Z electrodes. The ZNPM electrode showed superior electrochemical capacitive performance and improved electrical conductivity with a high specific capacitance of 2072.52 F g −1 at 5 mA, and a high energy density of 31 Wh kg −1 at a power density of 107 W kg −1 . Overall, ZNPM is a promising combination electrode material that can be used in supercapacitors and other electrochemical energy conversion/storage devices.
