TLDR
In this paper, the authors show that the mechanism of electrochemical alloying is electrochemically-driven solid state amorphization, a process closely analogous to the diffusive solid-state amomorphization of thin films.About:

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.

All‐Solid Lithium Electrodes with Mixed‐Conductor Matrix
TL;DR: In this paper, the concept of all-solid composite electrodes is presented, which contains a finely dispersed reactant,, in a solid mixed-conducting matrix, and the polarization is found to be comparable to values typical of highly porous electrode systems in molten salt electrolytes.
