Incorporation of α-MnO2 Nanoflowers into Zinc-Terephthalate Metal–Organic Frameworks for High-Performance Asymmetric Supercapacitors

“…On the other hand, supercapacitors can provide high power and undergo longer charging and discharging cycles. They have been successfully employed in various applications as multiresponsive healable supercapacitors, piezoelectric-driven self-charging supercapacitors, and in wearable and portable electronic devices by assembling the supercapacitor as a device with flexible electrodes. , Researchers are currently focused on designing electrode materials with different morphologies and larger surface areas to increase their electrochemical performance. , However, factors like poor ion diffusion and inadequate structural stability prevent them from being used in certain fields that need high rate and durable energy conversion and storage . This drawback of poor energy density can be overcome by selecting and properly optimizing electrode materials of the supercapacitors. , …”

Copper-Cobalt-Based Sulfides: Strategy To Boost Energy Storage Performance Utilizing the Synergistic Effect of a Double Metal Ion

“…18 Along with the structural phenomena, the improved electroactivity, ion transport, and electron conductance are enormously tied up with the integrated architectures, orientations, and hierarchical morphological features of the electrode material. 19 The further improvement of MMSs can be amended by tuning the porosity, ion transport diffusive passage, electroactive surface area, and electrical conductivity of the electrode material, which boosts the rate and capacitive performances of the PC device. Thus, the electrode fabrication in a one-step and binder-free protocol effectively increases the interfacial properties, dismisses mechanical degradation, avoids the dead volume of polymer binder, and sustains structural advantages of the material under harsh electrochemical circumstances, with the essence of the charge/discharge process and prolonged cycling ability of the material.…”

Coupling W18O49/Ti3C2Tx MXene Pseudocapacitive Electrodes with Redox Electrolytes to Construct High‐Performance Asymmetric Supercapacitors

“…Due to the synergistic effects between metal oxides and the added functional materials, these composites exhibit improved capacitive performance, originating from enlarged pseudocapacitances of metal oxides as well as additional capacitances from the added functional materials. [26][27][28][29] Note here that physical synthesis of such composites might not be conductive to the formation of strong synergistic effects between metal oxides and the added functional materials. Among various binary/ternary metal oxides, tungsten oxides (WO x , 2 ≤ x ≤ 3) are the most promising pseudocapacitive electrode materials since they feature excellent intrinsic properties (e.g., environmental friendliness, outstanding electrochemical stability).…”
