Abstract
The attempts to tailor the physical properties of barium titanate (BTO) to qualify it as a promising cathode for metal-ion batteries are interesting strategies. Herein, the paper attempts to modify the structure of BTO via electrochemical insertion of Mg ion within the framework of BTO. Introduction of Mg2+ ions within the framework of BTO drives the characteristic ferroelectric transition from 388K to 393K; furthermore, heat treatment of BTO beyond ferroelectric transition temperature Tc redistributes Mg ions within the framework of BTO, which results in downshifting of the Tc near the room temperature. XRD results confirm magnesiation and heat treatment of the magnesized BTO stimulates structure transformation from tetragonal to a cubic phase. The synthesized liquid Mg-electrolyte has exhibited an excellent LSV and Mg-platting/stripping. The assembled Mg/BTO cells with magnesized BTO cathode has relatively high initial specific capacity of 179.7 mAhg−1, compared with the pristine BTO of 72.5 mAhg−1.
