“…Outstanding electrochemical properties in the form of enhanced specific capacitance were also achieved for carbon/carbon EDLC using a mixture of [BMIm][OMS] and a polymer electrolyte poly(vinylalcohol) ammonium acetate (PVA–CH 3 COONH 4 ) in a cell reported by Liew et al, where the IL increases the conductivity of the electrolyte; a P S of 18.4 kW kg −1 and an ED of 0.17 Wh kg −1 were observed at ambient temperatures. In the recent years, imidazolium‐cation based ILs like [EMIm][DCA] and [EMIm][SCN] have been reported with conductivities above 20 mS cm −1 .…”

Electrochemical capacitors (ECs) are a vital class of electrical energy storage (EES) devices that display the capacity of rapid charging and provide high power density. In the current era, interest in using ionic liquids (ILs) in high‐performance EES devices has grown exponentially, as this novel versatile electrolyte media is associated with high thermal stability, excellent ionic conductivity, and the capability to withstand high voltages without undergoing decomposition. ILs are therefore potentially useful materials for improving the energy/power performances of ECs without compromising on safety, cyclic stability, and power density. The current review article underscores the importance of ILs as sustainable and high‐performance electrolytes for electrochemical capacitors.

“…It was also observed that the polymer electrolyte exhibited a wider potential stability range. Addition of BMImTf ionic liquid in PVA/CH 3 COONH 4 PE system [82] resulted in the polymer electrolyte exhibiting strong adhesive properties. Thus, better electrode-electrolyte interfacial contact can be provided.…”

Ionic liquids (ILs) are molten salts at ambient temperature and consist of poorly coordinating cations and anions. They have good electrical conductivity with a wide voltage window and high thermal stability, but negligible vapor pressure. ILs can enhance ionic conductivity when added to polymer electrolytes. Conductivity enhancement is due to the additional ions supplied by the IL, the plasticizing nature of the IL and the low viscosity that facilitates ion mobility. The plasticizing nature of ILs softens the polymer chain giving rise to easier polymer segmental motion. Increase in polymer segmental motion implies that IL can increase amorphousness of a polymer electrolyte (PE). This article discusses the involvement of ionic liquid as electrolytes in selected devices, namely dye sensitized photovoltaics, batteries, fuel cells and supercapacitors.

“…Except for the hydrolysis and organic electrolyte, the ionic liquid is also considered to prove the electrochemical potential window of the electrolyte used in the energy storage devices. Liew et al [24] report the investigation of ionic liquid-doped ion conducting polymer electrolytes for carbon-based EDLCs (electric double layer capacitors), and they get higher specific capacitance in EDLC comprising ionic liquid-doped polymer electrolytes.…”

Carbon-based materials are typical and commercially active electrode for supercapacitors due to their advantages such as low cost, good stability and easy availability. In the light of energy storage, supercapacitors mechanism is classified into EDLCs (electrochemical double layer capacitors) and pseudocapacitors. Multidimensional carbon nanomaterials (active carbon, carbon nanotube, graphene, etc.), carbon-based composite and corresponding electrolyte are the critical and important factor in the eyes of researcher. In this minireview, we will discuss the storage mechanism and summarize recent developed novel carbon and carbon-based materials in supercapacitors. The techniques to design the novel nanostructure and high performance electrodematerials that facilitate charge transfer to achieve high energy and power densities will also be discussed.
