The insertion into spinel occurs at potential 300mV more negative to that of insertion into anatase and about 40mV positive to that into rutile. The specific capacity (160mAh/g) is comparable with that of TiO2 polymorphs. Due to the relatively negative potential of the insertion and significantly lower tendency to self-discharge Li-Ti-O spinel is more convenient for use in 2V lithium ion battery than other active physes in the Li-Ti-O system.
