The galvanostatic discharge curves show that the best performance is obtained for sol-gel preparation. The oxides have been characterized by XRD, surface area, OCV and XPS measurements. The effect of preparation method on the electrochemical lithium insertion is discussed in terms of thermodynamical and kinetical properties. The preparation of spinel oxide host by sol-gel seems very promising.

However, taking into account the specific capacity of the electrodes studied at 2 V, the sequence will appear inverted: LiMn 2 O 4 (40 mAh/g)> LiCo 2 O 4 (10 mAh/g)> LiFe 2 O 4 (0.1 mAh/g). ...
