On the Beneficial Effect of MgCl₂ as Electrolyte Additive to Improve the Electrochemical Performance of Li₄Ti₅O12 as Cathode in Mg Batteries.

ABSTRACT: Magnesium batteries are a promising technology for a new generation of energy storage for portable devices. Attention should be paid to electrolyte and electrode material development in order to develop rechargeable Mg batteries. In this study, we report the use of the spinel lithium titanate or Li₄Ti₅O12 (LTO) as an active electrode for Mg2+-ion batteries. The theoretical capacity of LTO is 175 mA h g-1, which is equivalent to an insertion reaction with 1.5 Mg2+ ions. The ability to enhance the specific capacity of LTO is of practical importance. We have observed that it is possible to increase the capacity up to 290 mA h g-1 in first discharge, which corresponds to the reaction with 2.5 Mg2+ ions. The addition of MgCl₂·6H₂O to the electrolyte solutions significantly improves their electr
