The hydrolysis - condensation process produces TiO2 nanoglues consisting of TiO2 nanoparticles , providing strong adhesion between nanofibers and the current collector as well as between nanofibers , rendering favourable transporting properties of electrons and Li ions in the TiO2 nanofiber electrode , and eventually leading to the excellent performance of Li ion batteries exhibiting an excellent initial Coulombic efficiency ( ~ 85 % ) , cycle performance up to 100 cycles , and high rate capability ( 60 % at 5 C ) .
