It is suggested that in practical nonaqueous battery systems the alkali and alkaline earth metals are always covered by a surface layer which is instantly formed by the reaction of the metal with the electrolyte. This layer, which acts as an interphase between the metal and the solution, has the properties of a solid electrolyte. The corrosion rate of the metal, the mechanism of the deposition‐dissolution process, the kinetic parameters, the quality of the metal deposit, and the half‐cell potential depend on the character of the solid electrolyte interphase (SEI).read more

Correlation between cycling efficiency and surface morphology of electrodeposited lithium. Effect of fluorinated surface active additives
TL;DR: In this article, the authors investigated the cycleability of a lithium anode in two solutions containing LiClO 4 : (i) a propylene carbonate (PC) solution and (ii) a blended solution consisting of PC, ECC, and 1,2-dimethoxyethane (DME) (volume ratio = 1:1:2).

On the crystallography and reversibility of lithium electrodeposits at ultrahigh capacity

TL;DR: In this paper, Li deposits undergo a morphological transition to produce dense structures, composed of large grains with dominantly (110)Li crystallographic facets, and the resultant Li metal electrodes manifest fast kinetics for lithium stripping/plating processes with higher exchange current density, but simultaneously exhibit elevated electrochemical stability towards the electrolyte.
