Since the faradaic mechanism involves both the bulk and the surface of the electrodes, pseudocapacitors exhibit almost double the energy density compared to EDLCs. Starting from the ceramic materials (e.g., IrO 2, RuO 2, NiO), novel materials have been investigated over the past few decades, such as conducting polymers and other oxides [1, 8, 21], which can make …
