In‐Depth Mechanism Understanding for Potassium‐Ion Batteries by Electroanalytical Methods and Advanced In Situ Characterization Techniques

“…The current-potential curve of the battery is plotted under numerous sweep rates and given cycle numbers. [33] In 1997, Henrik's group studied the capacitance effect of nanoporous TiO 2 electrodes in lithium-ion batteries and proposed that the power function…”

Surface Diels–Alder adducts on multilayer graphene for the generation of edge-enriched single-atom FeN4 sites for ORR and OER electrocatalysis

“…6D, inset), and the obtained solution resistance (R s ), charge-transfer resistance (R ct ) and constant phase elements (CPEs) are summarized in Table 4. 115 The CPE-T parameter is related to pseudocapacitance and CPE-P is related to the depressed semicircle in the EIS plot. 116 As expected, MLGdppz@Fe(240N 2 ) provided the best charge transport efficiency with the smallest R ct of 15.87 U cm À2 , while MLG-dppz showed the highest R ct of 131.00 U cm À2 .…”

Mechanochemically Synthetized PAN-Based Co-N-Doped Carbon Materials as Electrocatalyst for Oxygen Evolution Reaction

“…Electrochemical impedance spectroscopy (EIS) studies were conducted for the different cobalt-doped PAN-N samples and the reference ( Figure 5 d). The EIS results were fitted based on the equivalent circuit ( Figure 5 d, inset), and the obtained solution resistance (R s ) and charge-transfer resistance (R ct ) are summarized in Table 3 [ 58 ]. As expected, PAN-N/3%Co had the smallest R ct of 152.55 Ω/cm 2 , while PAN-N/10%Co had the highest R ct of 528.00 Ω/cm 2 .…”
