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.
