Cyclic voltammograms for 10 mM CHP on HU-RGO–modified GC electrodes, as well as comparative voltammograms for bare and Fe 3 O 4-modified GC electrodes. The suffix denotes the number of times the current values of the cyclic voltammograms were scaled for ease of comparison.

Energy storage through intercalation reactions:

At the anode side, graphite is the most successful anode material, although a wide array of other hard (disordered) and soft (ordered) carbons have been studied extensively [107, 117]. In practice, almost all of the 372 mAh/g theoretical capacity is utilized, but the volumetric capacity is rather low (∼800 mAh/cm 3 ) and the power density is limited to regimes where Li-plating does not occur
