Oxygen deficient Mo x O y 200 nm-thick particles were synthesized by a citrate sol-gel method using ammonium heptamolybdate tetrahydrate as a source of Mo and heat treated with a small fraction of zirconia under reducing atmosphere. The samples were investigated by Xray powder diffraction (XRD), thermal gravimetric analysis (TGA), scanning electron microscope (SEM) and Raman spectroscopy (RS). The structural analyses show that the composite is a blend formed by layered α-MoO 3 , orthorhombic oxygen deficient phases MoO 3-δ with δ=0.25 (γ-Mo 4 O 11) and α-ZrMo 2 O 8. The insertion of lithium into the lattice was performed by electrochemical method. Redox peaks were observed for the MoO 3-δ composite attributed to distinct Li +-ion insertion/extraction reactions in the MoO 3 and Mo 4 O 11 hosts. The cyclic performance revealed improved reversibility, rate capability, and electrochemical stability of the ZrMo 2 O 8-decorated composite with respect to the bare molybdenum oxides. At C/10 rate, the composite delivered a stable reversible capacity of 135 mAh g-1 after the 50 th cycle. At a rate of 2C the reversible capacity is maintained at 118 mAh g-1 , approximately twice the capacity observed for the MoO 3 particles alone.

TNAs (Titanium dioxide nanotube arrays) were synthesized by electrochemical anodization and these TNAs were annealed in different gas atmosphere such as argon, air, hydrogen and nitrogen. This annealing in different atmosphere brought variation in crystallite size (27 ~ 33 nm), which influences on electrochemical properties. The specific capacity of Ar, Air, N 2 and H 2 -annealed TNAs was around ~165, 185, 177 and 190 mAh g -1 , respectively. The crystallite size of anatase TNAs seemed to be responsible for the change in lithium storage capacity, indicating that structural changes of TNAs were playing major role in electrochemical properties.
