Figure 2. GCD of half-cells with (A) PE, (B) PE1VC, (C) PE2VC and (D) PE4VC electrolytes at different rates; (E) Rate capability of the NFM@CTA-4||Na half-cells with the four electrolytes; Cycling performance of the NFM@CTA-4||Na half-cells with the four electrolytes at (F) 1 C and (G) 10 C; (H) Rate capability and (I) Cycling performance of the NFM@CTA-4||Na half-cells with PE1VC at 90 °C. Solid spheres indicate cycling capacity and hollow spheres indicate Coulombic efficiency.
