Following Grahame, in a Faradaic process, charged particles transfer across the electrode, from one bulk phase to another. Thus, in a Faradaic process, after applying a constant current, the electrode charge, voltage and composition go to constant values.

What are faradaic reactions?

Faradaic processes are defined as those which obey Faraday's law, that is the amount of chem- ical reaction occurring is directly proportional to the amount of charge passed across the elec- trode boundary. When the system is in a steady-state the application of this definition is simple: all the current is faradaic.

What is pseudocapacitive behavior?

Pseudocapacitive processes lead to a charge-dependent, linear capacitive behavior, as well as the accomplishment of non-faradaic double-layer capacitance in contrast to batteries, which have a nearly charge-independent behavior.
