Cell voltage as a function of capacity at different C-rates and temperatures. Discharge voltage from CDT protocol is plotted against capacity with histograms of the final cell capacity shown in the inset. Cells at 25 °C show a higher average capacity than cells at the other two temperatures with final cell capacities reaching 4 Ah. Cells discharged at 5 °C and 40 °C show a capacity of less than 3.9 Ah. At all operating conditions, the cell voltage shows a linear trend until approximately 3.4 V followed by a knee-point. Based on the standard deviation σ, the capacity deviation is the largest for cells at 25 °C at all C-rates.
