Free QuotePseudocapacitors store energy through reversible redox reactions that occur on the surface of their electrode materials. The term “pseudocapacitance” refers to the electrochemical charge storage that is associated with these reversible redox reactions, as opposed to “double-layer capacitance” which involves purely physical charge separation.
There is an urgent global need for electrochemical energy storage that includes materials that can provide simultaneous high power and high energy density. One strategy to achieve this goal is with pseudocapacitive materials that take advantage of reversible surface or near-surface Faradaic reactions to store charge.
In a pseudocapacitive electrode, different charge storage mechanism can be distinguished such as underpotential deposition, redox reaction of transition metal oxides, intercalation pseudocapacitance, and reversible electrochemical doping and de-doping in conducting polymers .
The introduction of pseudo-capacitors that exhibits higher charge storage capacity without losing their powerful output capability has provided a considerable advancement in the field of electro-chemical energy storage (EES) systems.
Pseudo-capacitors have revolutionized the field of supercapacitors (Fig. 1) owing to distinct electrochemical features for high charge storage capability as well as enhanced energy density due to offering an efficient passage to charge transfer .
For pseudocapacitor, the total capacitance is the sum of pseudocapacitive contribution through electronic charge transfer and the electric double layer component at the electrode and electrolyte interface. Pseudocapacitance is a faradic charge storage mechanism based on fast and highly reversible surface or near surface redox reaction.
