the difference between energy storage and supercapacitors
The storage mechanism difference between amorphous and anatase as supercapacitors
The only difference between them is the crystal structure, as shown in Fig. 1. Some studies have shown that amorphous-nanostructured TiO 2 exhibited better rate capacitance than that of anatase-nanostructured TiO 2 due to larger diffusion coefficient of lithium in amorphous TiO 2 as lithium batteries [ 22 ].
