Abstract: A significant improvement of the current lithium ion battery performance is needed to meet the needs of large-scale applications. Anode materials such as those based on tin/tin dioxide have shown the potential to easily increase the current anode capacity by two to three folds. Previous research has greatly improved the capacity retention of these `new¿ materials in prolonged cycling but the issues of initial irreversible capacity loss (ICL) and rate performance remain outstanding. This thesis study is focused on the design and synthesis of tin-based anode materials with high capacity, low ICL, stable cycling performance and high rate capability. The emphasis is on the design and fabrication of 3D hierarchical structures and their optimization for battery applications. There are also efforts on using composites (composites of tin/tin oxide with graphene, spinel lithium titanate (Li4Ti5O12), or TiO2) to optimize the reversibility of the tin-based anodes.
