Abstract
The present disclosure relates to a negative electrode material and methods of preparation and use relating thereto. The electrode material comprises a plurality of electroactive material particles, where each electroactive material particle includes an electroactive material core and an electronically conductive coating. The method includes contacting an electroactive material precursor including a plurality of electroactive material particles with a solution so as to form an electronically conductive coating on each of the electroactive material particles. The solution includes a solvent and one or more of copper fluoride (CuF2), titanium tetrafluoride (TiF3 or TiF4), iron fluoride (FeF3), nickel fluoride (NiF2), manganese fluoride (MnF2, MnF3, or MnF4), and vanadium fluoride (VF3, VF4, VF5). The electronically conductive coating includes a plurality of first regions and a plurality of second regions. The plurality of first regions include lithium fluoride. The plurality of second regions include one of copper, titanium, iron, nickel, manganese, and vanadium.
