Comparison between electric double layer capacitors and pseudocapacitor

EDLC	Pseudocapacitor
Good cyclic stability	Greater specific capacitance
Good power performance	Greater energy density
Formation of the double layer at the interface	No such layer formation
No redox reaction i.e., non-faradaic	Redox reactions, i.e., Faradaic
No mechanism failure	Depends upon redox reactions
