Abstract
A method for forming a prelithiated, layered anode material includes contacting an ionic compound and a lithium precursor in an environment having a temperature ranging from about 200° C. to about 900° C. The ionic compound is a three-dimensional layered material represented by MX, where M is one of calcium (Ca) and magnesium (Mg) and X is one of silicon (Si), germanium (Ge), and boron (B). The lithium precursor is selected from the group consisting of: LiH, LiC, LiOH, LiCl, and combinations thereof. The contacting of the ionic compound and the lithium precursor in the environment causes removal of cations from the ionic compound to create openings in interlayer spaces or voids in the three-dimensional layered material thereby defining a two-dimensional layered material and also causes introduction of lithium ions from the lithium precursor into the interlayer spaces or voids to form the prelithiated, layered anode material.
