Electrochemical performance of hard carbon anode in different carbonate‐based electrolytes

The electrolytes of 1 M NaFSI dissolved in various carbonate solvents containing EC, PC and/or DMC have been investigated to find out the most compatible electrolyte composition with hard carbon (HC) anode in Na‐ion batteries (NIBs). The physical properties including viscosity and conductivity were...

Description
Summary:The electrolytes of 1 M NaFSI dissolved in various carbonate solvents containing EC, PC and/or DMC have been investigated to find out 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.
