Fig. 15. (a) Voltage profiles of various materials with some solubility in Li during Li deposition at a current density of 10 μA cm−2; (b) shifted voltage profiles of various materials with negligible solubility in Li during Li deposition at a current density of 10 μA cm−2; the horizontal gray lines show 0 V versus Li in (a) and (b).
