Fig. 7. Variation of the EC concentration in the solvent between 30 wt% and 100 wt% with 1.2 M LiPF6.
a Number of SEI molecules after a simulated contact time of Li with the electrolyte of 1 µs over height. The dashed lines represent the initial lithium metal surface (left) and the maximum electron transport distance (right). b SEI porosity after 1 µs over height for the investigated EC weight fractions. c SEI thickness evolution for the investigated EC weight fractions within 1 µs.
