Nanosized Anatase TiO2 with Exposed (001) Facet for High‑Capacity Mg2+ Ion Storage in Magnesium Ion Batteries
Nanosized anatase TiO2exposed (001) facet doubles the capacity compared to the micro-sized sample ascribed to the interfacial Mg2+ion storage.Anatase TiO2exposed (001) facet displays a significantly higher capacity of 312.9 mAh g-1in 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.

As demand for safe, low-cost energy storage grows, rechargeable magnesium batteries (MIBs) offer a promising alternative to lithium-ion technology—yet their development is hindered by the sluggish diffusion of Mg 2+ within conventional electrode lattices. Now, researchers from Chongqing University and the University of Oxford, led by Dr. Jili Yue, Dr. Guangsheng Huang, and Prof. Fusheng Pan, have unveiled a nanostructured anatase TiO 2 cathode that exposes the highly reactive (001) facet, doubling capacity and setting a new benchmark for Mg 2+ storage performance.
