NOVELTY - The process comprises shaping a mixture of particles of a cathode or an anode material and a binder to form a shaped lithium ion battery electrode in which the particles are held together by the binder, and applying an alumina coating to the shaped lithium ion battery electrode via an atomic layer deposition process and onto surfaces of particles of the cathode material via the atomic layer deposition process, and mixing the coated particles with the binder. The coating has a thickness of 2-20 Angstrom . The particles have a longest dimension of up to 5 mu m.    USE - The process is useful for preparing a lithium ion battery electrode, where the battery is useful in industrial applications such as electric vehicles, hybrid electric vehicles, plug-in hybrid electric vehicles, aerospace and e-bikes, for operating electrical and electronic devices, such as computers, cameras, video cameras, cell phones, personal digital assistants, MP3 and other music players, televisions, toys, video game players, household appliances, power tools and for medical devices such as pacemakers and defibrillators.    ADVANTAGE - The process is capable of economically preparing the lithium ion battery electrode with high cycling capacities and improved stability thus increasing performance of the battery.    DETAILED DESCRIPTION - The process comprises shaping a mixture of particles of a cathode or an anode material and a binder to form a shaped lithium ion battery electrode in which the particles are held together by the binder, and applying an alumina coating to the shaped lithium ion battery electrode via an atomic layer deposition process and onto surfaces of particles of the cathode material via the atomic layer deposition process, and mixing the coated particles with the binder. The coating has a thickness of 2-20 Angstrom . The particles have a longest dimension of up to 5 mu m. During the atomic layer deposition process, the reactants diffuse through the binder, and react at the surface of the particles to coat particles in the electrode.
