“…The best cyclic stability and low-cost NiO modified carbon electrode is a good option as a positive electrode for supercapacitors. Similarly, PANI/Co 3 O 4 [148], RuO 2 /CNT [149], PANI/MnO 2 [150], a Co(OH) 2 film [151] MnO 2 [152], and a PTh/MWCNT composite [153] were also studied for supercapacitor applications.…”

Supercapacitors (SCs) have received much interest due to their enhanced electrochemical performance, superior cycling life, excellent specific power, and fast charging–discharging rate. The energy density of SCs is comparable to batteries; however, their power density and cyclability are higher by several orders of magnitude relative to batteries, making them a flexible and compromising energy storage alternative, provided a proper design and efficient materials are used. This review emphasizes various types of SCs, such as electrochemical double-layer capacitors, hybrid supercapacitors, and pseudo-supercapacitors. Furthermore, various synthesis strategies, including sol-gel, electro-polymerization, hydrothermal, co-precipitation, chemical vapor deposition, direct coating, vacuum filtration, de-alloying, microwave auxiliary, in situ polymerization, electro-spinning, silar, carbonization, dipping, and drying methods, are discussed. Furthermore, various functionalizations of SC electrode materials are summarized. In addition to their potential applications, brief insights into the recent advances and associated problems are provided, along with conclusions. This review is a noteworthy addition because of its simplicity and conciseness with regard to SCs, which can be helpful for researchers who are not directly involved in electrochemical energy storage.

“…Numerous efforts have been devoted to overcome the disadvantages thus improving the electrochemical performance of manganese oxides. − Up to now, one popular approach to introduce conductive materials (such as carbon, conductive polymers etc. ) − has been to fabricate MnO 2 /conductive material nanostructures. However, most of the conductive materials in these nanostructures are difficult to incorporate into the structures of the manganese oxides, leading to the restriction of the enhancement in conductivity because the conductive amelioration for the bulk MnO 2 is only limited to the interfaces between MnO 2 and conductive materials .…”

We herein report a kind of nickel-doped ultrathin δ-MnO 2 nanosheets prepared using a facile chemical bath deposition method. The obtained δ-MnO 2 materials have 2D ultrathin nanosheet structures with a few atomic layers. Electrochemical measurements indicate that an appropriate amount of nickel doping can remarkably improve the specific capacitance of the δ-MnO 2 and that 1.0 mol % nickel-doped δ-MnO 2 nanosheets display the best specific capacitance of 337.9 F g −1 at 1 A g −1 . The specific capacitance can maintain at 158 F g −1 even as the current density increases to 20 A g −1 , demonstrating that the electrode material possesses good rate performance. In addition, the discharge capacity fading from 160.9 to 158.8 F g −1 is slight after 4000 cycles, and the corresponding capacitance retention is as high as 98.6%. The good rate capacity and stability of the δ-MnO 2 nanosheets can be attributed to the ultrathin structure of a few atomic layers which provides large surface areas and lots of reactive active sites. Moreover, the appropriate amount of nickel ion doping at atomic level improves the conductivity of the δ-MnO 2 material.

“…The other energy storage principle is dened as a pseudocapacitor in which electrical energy is stored by Faradaic reactions such as redox reactions, intercalation, or electrosorption. 9 The most studied materials for pseudocapacitors are conducting polymers such as polyaniline 10 and transition metal oxides/hydroxides such as RuO 2 , 11 MnO 2 , 12,13 Co 3 O 4 , 14 Ni(OH) 2 /NiO 15 and a-FeOOH. 16 These materials always have high specic capacitances but are limited by poor cycling stabilities.…”
