Fig. 6: Electrochemical performance of Li | |SPAN full cells with three electrolytes.

a–c Cycling performance at (a) 25 °C, (b) 60 °C, and (c) −40 °C. d–f Pouch cell cycling performance at (d) 25 °C, (e) 60 °C, and (f) −40 °C (Inset: digital images of the pouch cells). All the specific capacity refers to discharge specific capacity, where 1 C equals 700 mA g−1. Source data are provided as a Source Data file.
