Perspective review evaluates criteria for distinguishing pseudocapacitive charge storage in electrode materials, clarifying mechanisms for high-rate energy devices.

Key Points

To establish clear physical definitions and diagnostic electrochemical criteria for distinguishing true pseudocapacitive behavior from other charge-storage mechanisms.
Critical analysis of electrochemical definitions, diagnostic criteria, and analytical techniques used to identify pseudocapacitance across energy-storage materials.
Clarifies the theoretical distinction between surface faradaic charge transfer and bulk diffusion-controlled battery-like redox reactions.
Identifies kinetic signatures and operational metrics required to rigorously demonstrate pseudocapacitive charge storage.
