Mark N. Obrovac,Leif Christensen +1 more
TL;DR: In this article, the structural changes in silicon electrochemically lithiated and delithiated at room temperature were studied by X-ray powder diffraction, and it was shown that highly lithiated amorphous silicon suddenly crystallizes at 50 mV to form a new lithium-silicon phase, identified as This phase is the fully lithiated phase for silicon at room-temperature, not as is widely believed.

Chemical diffusion in intermediate phases in the lithium-silicon system. [415/sup 0/C]
C.J. Wen,R.A. Huggins +1 more
TL;DR: The equilibrium coulometric titration curve shows four intermediate phases in the Li-Si system at 415/sup 0/C as discussed by the authors, and the nominal compositions for these phases are Li/sub 12/Si/sub 7, Li-sub 7/Si-sub 3, Li/Sub 13/Si+sub 4, and Li/ Sub 22/Si−sub 5, respectively.
