Original Abstract Submitted
the present disclosure provides a method for preparing an electroactive material for an electrochemical cell that cycles lithium ions. the method includes immersing a plurality of electroactive material particles in an aqueous solution and adding one or more fluorinated lithium salts to the aqueous solution to form a protective particle coating on each of the electroactive material particles of the plurality of electroactive material particles, where the plurality of electroactive material particles defines the electroactive material. the protective particle coatings are continuous coatings that cover greater than or equal to about 95% of a total exposed surface area of each electroactive material particle of the plurality of electroactive material particles.
