Double-shelled Co^sub 3^O^sub 4^@TiO^sub 2^@C yolk-shell spheres as anode material for enhanced cycling stability of lithium ion batteries

In this paper, double-shelled Co3O4@TiO2@C yolk-shell spheres have been successfully synthesized for enhanced the cycling stability of lithium ion batteries (LIBs). The inter-layer SiO2 as a sacrificial layer is removed by LiOH ethylene glycol/water solution at hydrothermal treatment, while the Co3O...
