Ternary TiO2/SiOx@C nanocomposite derived from a novel titanium–silicon MOF for high-capacity and stable lithium storage

Abstract

A novel titanium–silicon MOF precursor was first designed and constructed via a facile solvothermal process. After subsequent pyrolysis, the derived ternary TiO₂/SiO_x@C nanocomposite exhibited superior lithium storage performances, which was attributed to their all-in-one architecture of synergistic components, including stable-cycling nanostructured TiO₂, high-capacity SiO_x and high-conductivity carbon matrix.
