As an alternative of the graphite-based anode in lithium ion batteries (LIBs), the TiO2-based anode has drawn attention with its stability and long operation life especially in the field of electric vehicles (EVs). Although the lithium titanate (LTO, Li4Ti5O12, theoretical capacity of 175 mAh g-1) anode is commercially available, there are constant needs to improve the anode capacity with TiO2-based materials because they have much higher theoretical capacities compared to LTO. In this study, a lotus-root shaped TiO2 (LR TiO2) material was synthesized using a cetyltrimethylammonium hydroxide as a soft template in aueous solution and heat treated in three different temperatures(450, 550, 700℃) and applied as a anode material for LIB with expectancy to have large pores for lithium insertion and thus show better electrical properties. |
