Effect of thermal treatment on the electrochemical performance of TiO.sub.2/Anatase cathodes for Li.sup.+/Mg.sup.2+ batteries

In this study, nanostructures of TiO.sub.2(B)/Anatase phase with different ratios were synthesized by different processes including a calcination at 450 °C for 4 h. The stability tests showed that the TiO.sub.2(B)/Anatase phase was stable up to 1 h of calcination. The sample featuring the TiO.sub.2(B)/Anatase phase showed a 72% discharge retention capacity. On the other hand, the chemical performance of the electrodes was assessed by means of charge and discharge tests at different rates, in a range of 0.01-2 V vs. Mg/Mg.sup.2+. The results showed a discharge capacity of 305 mAhg.sup.-1 for the samples featuring the TiO.sub.2(B)/Anatase phase.
