“…70 When the cells were soaked with 16 MΩ resistive deionized water, a remarkable drop in impedance occurs to 100 Ω depicted in Figure 9C,H. 43 In wet condition, the cells at lower frequency region shows a tail which is referred as diffusion of H 3 O + ion at the Ag electrode ( Figure 9) and at high frequency, a capacitive tail appears owing to the formation of Zn(OH) 2 at Zn anode for magnetite and Lithium substituted magnesium ferrite HEC. 34,71,72 In Figure 9G, H, for MgO and SiO 2 high-frequency semicircle loop is suppressing the Nyquist plots due to high values of bulk resistance R b .…”
