Nanosized Anatase TiO2 with Exposed (001) Facet for High-Capacity Mg2+ Ion Storage in Magnesium Ion Batteries

Highlights Nanosized anatase TiO2 exposed (001) facet doubles the capacity compared to the micro-sized sample ascribed to the interfacial Mg2+ ion storage. Anatase TiO2 exposed (001) facet displays a significantly higher capacity of 312.9 mAh g−1 in Mg–Li dual-salt electrolyte. The adsorption energi...

Description
Summary:Highlights Nanosized anatase TiO2 exposed (001) facet doubles the capacity compared to the micro-sized sample ascribed to the interfacial Mg2+ ion storage. Anatase TiO2 exposed (001) facet displays a significantly higher capacity of 312.9 mAh g−1 in Mg–Li dual-salt electrolyte. The adsorption energies of Mg2+ on (001) facet are much lower than the adsorption energies of Li+ on (001) facet, implying that the Mg2+ ion interfacial storage is more favorable.
