a, c Cycling stability and the corresponding energy density over 100 cycles at 1 C. b Cycling performance over 500 cycles at 5 C. d Rate capability. Comparative analysis of Na+ diffusion coefficients based on (e) GITT tests and rate CV curves. The active mass loading in the half cell is 2–3 mg·cm−2. f Galvanostatic charge-discharge curves, (g) cycling performance with N/P ratio of about 1.2, and (h) rate capability of Na-ion full cells. The C-rate is defined as 1 C = 120 mA g−1.
