Abstract
A process for the facile prelithiation of silicon-containing materials for use in lithium ion batteries is disclosed. The process can include using a lithium additive comprising LiSt, LiO—SiO—TiO—PO, LATP, LAGP, LLTO, LLZO, LiN, LiBF, LiCO, LiPO, lithium-enriched variations thereof, or combinations thereof. The resulting prelithiated materials demonstrate enhanced physicochemical properties providing for high target capacity and excellent cycle stability for the batteries prepared with the materials.
