Fig. 8

Pressure analysis (green lines, right-hand scale) of full-cells cycled at 55 °C at 0.2 C rate using a 0.35 M NaBOB in TEP, b 0.35 M NaBOB in TEP + 3 wt% PES and c 1 M NaPF6 in EC:DEC electrolyte solutions, as well as voltage profiles for the same cells (red lines, left-hand scale). Note that there is a natural leakage of the pressure cells specified to maximum 0.3 mbar h−1 by the supplier, and that the relative pressures have been corrected to reflect an estimate of the pressure evolved from the cell components during the galvanostatic cycling. The original pressure data is available in Fig. S19.
