Graphenated tantalum(IV) oxide and poly(4-styrene sulphonic acid)-doped polyaniline nanocomposite as cathode material in an electrochemical capacitor

A review on the use of carbon nanostructured materials in electrochemical capacitors

“…The proposed mechanism involves space charge density increase and attraction of protons . They are based on electrode charge storage mechanisms and require highly reversible surface redox processes between electrode‐electrolyte interfaces or through intercalation of ions . Their performances are governed by ion kinetics and electrode electron transport as well as the electrode‐electrolyte interface .…”

“…ECs are commonly classified into two categories, i.e. as pseudocapacitors and electrochemical double layer capacitors (EDLCs), subject to both the charge storage mechanism and material technology exploited in the fabrication of electrodes [10,46,74] ( Figure 4) [8,43,66,75,76].…”

“…Energy is stored electrostatically as opposite electric charges, i.e. through a charge separation mechanism ( Figure 5) [37,75,77,80]. Electrolyte ions are reversibly adsorbed into the micropores of the electrode material [29,69].…”

Electrochemical synthesis of polymer based on 4-(2-furyl) benzenamine: Electrochemical properties, characterization and applications

“…Furthermore, their potential use for advanced technological applications including light emitting diodes, photovoltaics, optical switches, anticorrosion protection and sensors has motivated the design and synthesis of new conjugated polymers with unique properties [6][7][8][9][10][11][12][13][14]. PANI and its derivatives are an important family of intrinsically conductive polymers which have been widely used in making of new electrical and optical devices [15][16][17][18][19]. High stability, low cost, easy preparation, and unique electrochemical properties of PANI offer a wide variety of applications [20][21][22][23].…”

Preparation of TiO2/boron-doped diamond/Ta multilayer films and use as electrode materials for supercapacitors

“…About 40% of the world Ta production is used for capacitors [22] which contain a Ta anode sintered in vacuum with a fine Ta powder and an anodic oxide film of Ta employed as a dielectric. In addition, exceptional corrosion resistance, high melting points, good mechanical strength, and excellent biocompatibility make tantalum capacitors ideal for use in harsh conditions [23][24][25]. Nanostructured Ta possesses large surface area high specific charge, and redox activity except the advantage of Ta bulk [26] and has promising application potential in supercapacitor.…”
