Abstract: | The electrolytes of 1 M NaPSI dissolved in various carbonate solvents containing EC, PC and/or DMC have been investigated to íìnd oul the most compatible electrolyte composition with hard carbon (HC) anode in Na-ion batteries (NIBs). The physical properties including viscosity and conductivity were measured to correlate with the electrochemical behaviors of these electrolytes. The Na/HC half-cell was used for testing the charge/discharge performance of prepared electrolytes at room temperature. This best medium for the solvation of NaFSI salt is the mixture of EC, PC and DMC with the ratio 3:1:1, respectively. Indeed, this electrolyte delivered a highest capacity of 335.6 mAh.g⁻¹, excellent capacity retention of 73.7 % for 100 cycles. |
