Popis: Rechargeable magnesium (Mg) battery with high volumetric energy density is one of the most promising candidates for next-generation safe and clean renewable energy sources. Just like rechargeable lithium battery, the development of anode materials beyond metal Mg will greatly promote the practical process of rechargeable Mg battery system. In this study, we propose a strategy to realize the reversible storage of Mg2+ in possible zero-strain layered transition metal oxides (Li2TiO3) via nanotechnology for the first time. The as-prepared layered Li2TiO3 anode shows good cycling stability with a highly reversible Mg2+ storage capacity of 110 mA h g−1. The unusual Mg storage mechanism with stable phase transition reaction is proposed by various ex situ analyzing and testing techniques which will help advance the development process of the long-life rechargeable Mg batteries.
