An ideal capacitor exhibits pure electrostatic (non-Faradaic) charge storage, resulting in a classic rectangular cyclic voltammogram.

The analysis

The retrieved literature consistently confirms that ideal capacitors, specifically electrical double-layer capacitors (EDLCs), display nearly rectangular cyclic voltammetry (CV) curves as a hallmark of non-Faradaic capacitive behavior.
