From: Rational electrolyte solvent screening for high-energy lithium metal batteries at low temperatures
a Cycling performance and b charge-discharge profiles of the Li | |NMC9055 pouch cell with the TFPM electrolyte at 25 °C. c Cycling performance of the Li | |NMC9055 pouch cell with the TFPM electrolyte at −40 °C. d Comparison of this work with state-of-the-art reported Li-metal pouch cells at low temperatures (≤ −20 °C). The source of the literature data shown in this figure can be found in Supplementary Information Table 725,40,47,48,49,50,51. Note: * represents excluding the weight of tabs and packing foil when calculating the specific energy. e Scheme showing the screening principle to balance the de-solvation and interphase stability in weak solvation solvent. f Radar plot with five aspects to evaluate the designed electrolytes. Ratings of 0 to 10 are given to each electrolyte (10 stands for ideal properties). Rationale for radar plot can be found in Supplementary Information Table 8. Source data are provided as a Source Data file.
