NOVELTY - The electrode (22,24) comprises an electroactive material. An oxide-based coating is formed on surface regions of electroactive material. A coating that is distinct from oxide-based coating formed from a non-aqueous coating process is formed over oxide-based coating. The coating is selected from the group consisting of: a fluoride-based coating, a carbide-based coating, and a nitride-based coating. The oxide-based coating comprises aluminum oxide. The thickness of oxide-based coating is less than or equal to about 5 nm and a thickness of coating is less than or equal to about 50 nm.    USE - Electrode for lithium ion electrochemical cell (claimed) such as lithium ion battery for use in electrochemical device, battery-powered vehicles and hand-held consumer electronic device such as hybrid vehicle or all-electrical vehicle, laptop computer, tablet computer, cellular phone and cordless power tools.    ADVANTAGE - The undesirable side reactions is prevented and the formation of solid electrolyte interphaseon the electrode surface and gas generation for use in electrochemical device are minimized. The deposition of transition metals or other compounds present within the electrochemical cell onto the surface of graphite or another negative electrode material is prevented. Therefore the fading of charge capacity to maintain the charge capacity of the electrochemical cell is avoided. The formation the formation of solid electrolyte interface layer on the electroactive material is avoided. The irreversible capacity loss in electrochemical cells is reduced. The reactivity of the underlying LTO and metal oxide coating is reduced and therefore the gas formation with an electrochemical cell over time is minimized. The storage stability and battery lifespan is increased. The deposition of the metals onto the negative electrode is prevented and formation of a solid electrolyte interface layer on the negative electrode to maintain charge capacity during charging and discharging of the lithium ion battery for greater than or equal to about 1,000 cycles is minimized.
