NOVELTY - Method (M1) for manufacturing electrode material, involves: (A) providing nanoparticles of titanium dioxide, lithium titanate, silicon, silicon oxide or a transition metal oxide, coated with a monocarboxylic acid having chain length of 7-26 carbon atoms; and (B) heat-treatment of the monocarboxylic acid coated nanoparticles of step (A) for carbonization of the monocarboxylic acid coating.    USE - For manufacturing electrode material, for electrochemical energy storage devices, particularly as active material for electrodes used in lithium and lithium ion batteries (claimed) for electric vehicles and for use of renewable energies.    ADVANTAGE - The method involves manufacturing electrode material by using nanoparticle-carbon-composite as active material for electrodes used in lithium and lithium ion batteries. The use of monocarboxylic acid for coating nanoparticles takes advantage of organic capping as dispersing agent to avoid particle agglomeration during preparation. Further, monocarboxylic acid coating, upon thermally-induced conversion into carbon, can contribute to electron conductive percolating network. The carbonization of monocarboxylic acid creates coating on electrode material. The electrodes based on nanoparticles take advantage of capping with monocarboxylic acids, and show improved high rate performance, higher capacities, and cycling stability; and demonstrate improved results in terms of combined reversible high rate performance, long-term cycle performance, and safety, particularly for titanium based composite materials, where operative potential window is within electrochemical stability window of common electrolytes. Thus, nanoparticle-carbon-composite provides appealing anode material candidate for realization of safe, high performance, and large electrochemical energy storage devices that are strongly required for development of sustainable electric vehicles and effective use of renewable energies. Advantageously, no additional carbon needs to be used for electrode preparation. Further, carbon-based coating increases electronic conductivity and inhibits particle agglomeration during subsequent electrode preparation process.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) electrode material (M') for electrochemical energy storage devices, particularly for lithium and lithium ion batteries prepared by the method (M1); and    (2) electrode comprising the electrode material (M') prepared by the method (M1).
