(a) Cycling performance and Coulombic efficiency of gSi@C anodes at a current density of C/10. (b) The corresponding galvanostatic charge-discharge profiles of gSi@C based half cell. (c) Cyclic voltammetry characteristic of gSi@C anodes. Scan rate: 0.2 mV sec−1. (d) C-rates cycling performance of gSi@C electrodes. (e) Comparison of the cycling performance and Coulombic efficiency between gSi@C and gSi based electrodes at a higher current density of C/2.
