a Cycling performance of Li | |Li symmetric cells in different electrolytes. b CE tests of Li | |Cu cells in different electrolytes using the Aurbach method at 25 °C. c Long cycle performance of Li | |Cu cells in different electrolytes at 25 °C. Inset: Localized enlarged figures from the 100th to 200th cycles. d Performance comparison of Li negative electrodes in terms of Li salt concentration, cycle life, and average CE (The source of the literature data shown in this figure can be found in Supplementary Table 6). e–g Voltage capacity curves in different electrolytes after different cycles: (e) 1 M LiFSI in DME; (f) 1 M LiFSI in DEA; (g) 1 M LiFSI in DEA/FB (1:1 v/v). Inset: enlarged view of the stripping process. h CE test of Li | |Cu cells with 1 M LiFSI in DEA/FB (1:1 v/v) LMCE using the Aurbach method at −20 °C and −40 °C. i Long cycle performance of Li | |Cu cells in 1 M LiFSI in DEA/FB (1:1 v/v) LMCE at −20 °C. Inset: voltage capacity curves after different cycles and the localized enlarged figure from the 300th to 500th cycles.
