Fig. 4. The electrochemical performance of electrolytes. (a) The rate performance of three Na‖NVP batteries. (b) The cycle performance and (c) corresponding galvanostatic charge/discharge curves of the NVP‖HC battery in the electrolyte containing 2 wt% GA additive at 1C. (d) Voltage-time profiles of the three Na‖Na symmetric cells at a current density of 1.0 mA cm−2. (e) Comparison of the properties of the electrolyte designed by us with those reported in the literature.48.
