Charge/discharge profiles of a CuMgTi-571 and b NaMNO2 at 0.1 C (12 mA g−1) between 2.0 and 4.3 V. c Cycling performances of CuMgTi-571 and NaMNO2 at 0.1 C (12 mA g−1) for 100 cycles. d Rate performances of Na0.62Mn0.67Ni0.23Cu0.05Mg0.09-2yTiyO2 and NaMNO2 from 0.1 C to 10 C (1 C = 120 mA g−1). Cycling and rate tests were conducted in a coin cell using Na metal as an anode at 25 °C. Hollow and solid circles in (c, d) represent charge and discharge capacity, respectively. Triangles represent coulombic efficiency.
