Extended Data Fig. 9 | Evolution of electrochemical behaviour over resting
and cycling. a, Electrochemical load curves for Na0.6[Li0.2Mn0.8]O 2 electrodes
charged to 4.5 V at a rate of 10 mA g−1, then rested at open circuit voltage (OCV)
for varying amounts of time before discharge at 10 mA g−1. b, c, Electrochemical
load curves for ribbon-ordered Na0.6[Li0.2Mn0.8]O 2 and honeycomb-ordered
Na0.75[Li0.25Mn0.75]O 2 electrodes respectively, cycled between 2.0 V and 4.5 V at a
rate of 10 mA g−1. First cycle blue.
