(a) Half-cell cyclability and (b) columbic delithiation efficiency under capacity limitation of 1800 mAh/g for Si-FLG formulation matrix (Formula A – 76% Si: 0% FLG: 12% Na-PAA: 12% Carbon. Formula B – 70% Si: 8% FLG: 12% Na-PAA: 10% Carbon. Formula C – 65% Si: 12% FLG: 14% Na-PAA: 9% Carbon. Formula D – 60% Si: 16% FLG: 14% Na-PAA: 10% Carbon). (c) First cycle voltage profile for half-cells of Si-FLG with Formula D, Si only and FLG only electrodes cycled between 1 V-5 mV without capacity limitation.
