Preparation and Characterization of Cathode Material for Magnesium Cells

Abstract

A cathode materials for magnesium cells MgTi₂O₅ was synthesized via sol-gel method in this work. TG/DTA, XRD, SEM were used to characterize the reaction and product. The results showed that the product is well-crystallized and gets uniform particle size. Simulation cells were assembled employing the product as positive electrode. Charge/discharge cycle test show that the product has good reversibility. The discharge capacities for MgTi₂O₅ is 50.2 mAh g^-1 after 50 cycles. The use of MgTi₂O₅ as active cathode materials for magnesium batteries in general shows great promise for secondary batteries.
