An in-depth study of the electrical characterization of supercapacitors for recent trends in energy storage system

Protic ionic liquids for sustainable uses

“…Supercapacitors (also known as electrochemical capacitors), have a higher energy density than dielectric capacitors, and are increasingly sought after for applications where high power density is required. This includes portable and flexible electronics, 213 hybrid electric vehicles, 214 and uninterrupted power supplies. 215 They can be classified either as electrical double-layer capacitors (EDLC), which store charge purely via non-faradaic processes, or as pseudocapacitors that are dominated by reversible redox reactions (faradaic processes) occurring at electrode–electrolyte interfaces, 216 or as hybrids.…”

Phenazine-integrated conjugated microporous polymers for modulating the mechanics of supercapacitor electrodes

“…where i(v) is the whole current at a constant potential v along with k 1 v and k 2 v 1/2 representing the currents generated through respectively the diffusion-controlled and capacitive processes (eqn ( 6)). Such values of k 1 and k 2 were determined based on the slope along with the intercept of eqn (7) as represented in Fig. 6a.…”

“…[1][2][3][4][5] They appear to be particularly suitable for application in electric vehicles, elevators, cranes, and power supply units. [6][7][8][9] Many diverse materials, including hydroxides, active organic moieties, carbonaceous materials, and metal oxides and sulfides, have been introduced as supercapacitor electrodes. [10][11][12][13] Supercapacitor electrodes based on inorganic moieties can be hazardous and environmentally destructive, while supercapacitor electrodes based on electroactive organic materials are attractive because of their availability, flexibility, sustainability, and eco-friendliness.…”

Improved Electrochemical Performance of Aqueous Hybrid Supercapacitors Using CrCo2O4 Mesoporous Nanowires: An Innovative Strategy toward Sustainable Energy Devices

“…Electrochemical energy storage (EES) systems possess widespread implications in medical, electronics, and smart gadgets. − In recent years, a variety of batteries and supercapacitors (SCs) have emerged as promising candidates in EES devices. − Although these emerging technologies can store and produce sufficient energy, batteries and SCs suffer from certain limitations. Recently, scientists have developed different types of EES systems including Li-ion batteries and Zn-ion batteries. , Currently, batteries encounter issues of limited power density, limited lifespan, and low charging speed, together with the widespread use of environmentally unfriendly electrolytes. , Although SCs meet the requirements of charging speed as well as power density, their low energy issues, which are far inferior to conventional batteries, , are inherent limitations.…”
