The anode materials of batteries are one area of research that have much room for improvement. The increasing performance requirements of battery systems, such as cycle life, capacity, and safety, leads to the exploration of new methods and processes for improving battery materials presently used. One system currently being researched as an anode for lithium ion batteries are titanium dioxide nanotubes, which can be grown on titanium metal substrates with anodization or with hydrothermal treatment of titania particles. This research project looks in to exploring defect generation in metallic oxides as a method of improving battery properties. According to a related study, electrochemical performance of anode materials such as titanium dioxide nanotubes can be improved with this method. Nanotubes were prepared by electrochemical anodization and were irradiated in hope of generating oxygen or titanium vacancies in the crystal lattice of the tube walls. Then they were put into coin cell batteries and were tested electrochemically. Results of this process of discussed.
