NOVELTY - Manufacture of an active electrode material involves providing a mixed niobium oxide, combining the mixed niobium oxide with a carbon precursor to form an intermediate material, heating the intermediate material under reducing conditions to pyrolyze the carbon precursor forming a carbon coating on the mixed niobium oxide and introducing oxygen vacancies into the mixed niobium oxide. The carbon precursor comprises polyaromatic sp2 carbon and is selected from pitch carbons and/or graphene oxide. USE - Manufacture of active electrode material used in composition for electrodes of lithium ion battery (all claimed) for electric vehicles. ADVANTAGE - The method produces active electrode material having improved dispersibility of particulate material, improved capacity retention and high specific capacity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of electrode; (2) active electrode material, which comprises oxygen-deficient mixed niobium oxide comprising a carbon coating comprising polyaromatic sp2 carbon; (3) composition, which comprises active electrode material and at least one component selected from binder, solvent, conductive additive and/or additional active electrode material; (4) electrode, which comprises active electrode material in electrical in contact with a current collector, and forms an anode as lithium-ion battery; and (5) use of carbon precursor, which comprises polyaromatic sp2 carbon selected from pitch carbons and/or graphene oxide to improve the properties of mixed niobium oxide for use as an active electrode material, optionally to improve the initial coulombic efficiency of the mixed niobium oxide and/or to improve the specific capacity of the mixed niobium oxide.
