Abstract

Confinement of ultra-small MgTi₂O₅ nanoparticles in carbon is demonstrated to be an efficient method for fabricating long cycle-life anode material for sodium ion batteries. Superior rate and excellent cyclic capabilities as well as high Coulombic efficiency of the MgTi₂O₅–C nanocomposite, obtained from pyrolysis of a single molecule precursor, are shown.
