Energy storage behavior kinetics analysis. (a–c) CV scans of the SnO2[O]rTiO2-PGN, Ad-SnO2-G, and Ana-SnO2-PGN anodes, respectively, at various speeds (0.1–10 mV s−1). (d,e) Plots of b-value versus voltage of cathodic and anodic scan, respectively. (f) Pseudo-capacitive contribution ratio (indicated as “contribution ratio, %”) under various scan rates. (g,h) The separation of capacitive and diffusion-controlled process contributions under 1 and 2 mV s−1. (i) Normalized contribution ratio bar plot of SnO2[O]rTiO2-PGN under various scan rates.
