SEM images for the Li plating morphology on copper substrates under a) 60 °C and b) 25 °C with the current density of 0.5 mA cm−2 and 0.5 mAh cm−2. a,b) Reproduced with permission.[ 75 ] Copyright 2019, Wiley‐VCH. c) schematic illustration demonstrating that a LiPF6 additive in LiTFSI–LiBOB electrolyte prevents the Al corrosion and improves the stability of Li metal.
