Lithium intercalates well in silicon and the integrity of the electrode is maintained even after several charge/discharge cycles but does lithium metal react with extremely dry fumed/pyrogenic silica.
Salam alaikum, Dear and brother Salman Sultan. I do not know if these references will help you or not. these are about lithium react with silica. I hope you will find useful these references.

Thank you very much for your effort. Carbon and now Silicon as a storage for Lithium ions is known but i wished to know the reaction of Lithium metal with SiO2 when it is dispersed in Lithium electrolyte solution.
However, i appreciate the time you took and wish you the best in your research activities.
Hi,
Si nanoparticles often present a thin SiO2 layer on their surface. While cycling, this layer is reduced to Si while Li2O is formed. This is a classical issue for silicon anode as this Li2O layer is not an efficient electronic conductor and may sometimes irreversibly trap Li. You may check our recent paper on the synthesis of core-shell silicon-carbon nanoparticles in a one step process by double stage laser pyrolysis. It allows the production of large quantity of this composite and greatly limits the formation of the native oxide on the surface of the silicon nanoparticles.
