Non-Aqueous Electrolytes for Lithium Ion Batteries.

摘要

An article comprising a silicon carbide and/or silicon metal-containing substrate and an environmental barrier layer overlaying the substrate, wherein the environmental barrier layer has a thickness up to about 5 mils (127 microns) and comprises a reaction-generated corrosion resistant metal silicate. A process is also provided for reacting a metal source and a silica source over the silicon carbide and/or silicon metal-containing substrate to form the environmental barrier layer comprising the reaction-generated corrosion resistant metal silicate.
