Li-ion storage properties of quasi-metallic silicon and Si electrodes. a First charge–discharge profiles of QMS(0.7) and Si electrodes at a C-rate of 0.05 C. b Charge areal capacity retention of both electrodes at 0.5 C with the corresponding Coulombic efficiency. c Specific capacity plots for both electrodes at different C-rates from 0.2 C to 5 C. d Electrode expansion ratio during 300 cycles for both electrodes. e Full-cell cycle retention at 1 C (3.3 mA cm−2) along with the coulombic efficiency
