a Ion conductivity of different electrolytes in a wide temperature range. b The activation energy of Li+ transport in SEI. c The activation energies for Li+ de-solvation at the negative electrode interface. Radial distribution functions and coordination numbers in d DEE, e DDE, and f DDE-PN. g C 1s, h N 1s, i Li 1s XPS spectra of SEI formed on the surface of Cu were measured after depositing lithium metal with a fixed capacity of 2 mAh cm−2 at a current density of 1 mA cm−2 on Cu in Li||Cu coin cells containing DEE, DDE, and DDE-PN electrolytes after 20 cycles.
