Titanium Oxide-Based Nano Anode Materials

5 Titanium Oxide-Based Nano Anode Materials 

Anatase Ti02 is generally considered to be the most electroactive Li insertion host among all Ti02 polymorphs. Many efforts were made to investigate anatase Ti02 for Li storage. The Li insertion and

The good Li storage of nanorutile Ti02 might because Li stores at the surface or amorphous surface layer of nanorutile 

Ti02(B) NWs attract more research interest since they show superior electrochemical performance as a Li+ insertion host than their bulk counterpart (Fig. 5.16). Ti02(B) NWs were prepared via a simple hydrothermal reaction. They could accommodate 0.91 Li to form Lio.9iTi02 (305 mAh/g) at 10 mA/g and show excellent rate performance, the intercalation capacities are around 200,155,125, 100 and 85 mAh/g at the rate of 200, 500, 1000, 2000 and 3000 mA/g. XRD patterns for Ti02(B) NWs at various states of charge shows no obvious expansion of lattice after Li-ion insertion.
