Electrochemical properties of SiO2-rGO@PPy electrodes in a Li half-cell between 0.1 and 3 V versus Li (a) CV curves of SiO2-rGO@PPy at various scan rates from 0.1 to 2.0 mV s−1. (b) Variation in the charge and discharge peak current (i) with the scan rate (v). (c) Volumetric response at a scan rate of 2.0 mV s−1, where the capacitive contribution to the total current is shown by the shaded region; (d) bar chart showing the contribution ratio of diffusion-controlled and capacitive contribution at various scan rates.
