IPC: H01M4/04
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 MX2, 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.

Abstract: The present disclosure provides a method for forming a layered anode material. The method includes contacting a precursor material and a first electrolyte. The precursor material is a layered ionic compound represented by MX2, where M is one of calcium and magnesium and X is one of silicon, germanium, and boron. The method further includes applying a first bias and/or current as the precursor material contacts the first electrolyte so as to remove cations from the precursor material to create a two-dimensional structure that defines the layered anode material. In certain variations, the method further include contacting the two-dimensional structure and a second electrolyte, and applying a second bias and/or current as the two-dimensional structure contacts the second electrolyte so as to cause lithium ions to move into interlayer spaces or voids created in the two-dimensional structure by the removal of the cations thereby forming the layered anode material.

Abstract: An electrode including an electrochemical layer defining a surface having a plurality of dimples formed thereon is provided. The dimples have an average lateral size greater than or equal to about 100 nm to less than or equal to about 100 μm, and an average depth greater than or equal to about 100 nm to less than or equal to about 50 μm. In certain variations, the dimples are formed in situ by applying a current to the electrochemical layer. In other variations, the dimples are formed by moving a roller having a plurality of shapes defined thereon along one or more surfaces of the electrochemical layer. In still other variations, the dimples are formed by contacting one or more surfaces of the electrochemical layer with a chemical etchant.
