The following thesis is concentrated on the development of TiO2Sb2O3 composite material through the hydrolysis of TiCl4 to be applied as anode material for lithium-ion batteries. Antimony (Sb) has been a material of interest due to its high capacity and good chemical properties. The TiO2 accommodated the harsh volume expansion that Sb encounters during the alloying process while still preserving the high capacity offered by Sb. Its electrochemical performance exhibited a stabilized capacity of 523 mAhg-1 after reaching 40 cycles with a capacity loss of 2.4% till reaching 100 cycles. High reversible capacity characteristics were present with an initial capacity of 427 mAg-1 at a current density of 50 mAg-1 in the first 10 cycles and finished with a capacity of 336 mAg-1. Results displayed that there was good contact between the electrode and electrolyte having well distribution of electrons and ions. Overall, its preparation, characterization, and performance were studied for each ratio prepared to see its significance on the electrochemical performance.
