WebDec 14, 2015 · Diffusion of Li in Li x Sn alloys was investigated using a density functional theory in order to fully understand the lithiation process in these types of Li ion batteries. Variation of the calculated open-circuit voltages of the Li x Sn alloys was found to agree well with experimental results. Diffusion coefficients of the Li in the Li x Sn alloys were … WebLithium metal self-diffusion is too slow to sustain large current densities at the interface with a solid electrolyte, and the resulting formation of voids on stripping is a major limiting factor for the power density of solid-state …
