Fig. 6

GITT curves and corresponding Na+ diffusion coefficients of a CuMgTi-571 and b NaMNO2 during the charge and discharge processes. c–f The average Na+ diffusion coefficient of CuMgTi-571 and NaMNO2 in different voltage regions. GITT tests were performed in coin cells using Na metal as an anode at 25 °C.
