Next, the impedance of nano-TiS2 in the battery-like and pseudocapacitive regions is analyzed in the same manner, with Nyquist plots being presented in Fig. . Compared to bulk-TiS2, the nano-TiS2 host material offers both smaller diffusion length and a higher surface area, impacting on the charge storage kinetics. Consequently, in the low-frequency region, an overall reduction of the solid-state diffusion-related P1 signals is observed in the DRT analysis (Fig. ), compared to bulk-TiS2. The P1 resistance also further decreases in nano-TiS2 in the
