Abstract

Lithium ion battery (LIB) is one of the most promising energy storage technologies and has rapidly taken over the markets of high performance rechargeable batteries for portable electronic devices. However, the application of LIB is limited by the safety problem and high-rate capability. Nowadays, more and more research has been focused on the synthesis and modification of new electrode materials. Nano-materials and nano-composite are expected to enhance the capacity and cycliability of LIB due to the novel morphology and structure.

This thesis focused on the fabrication of porous TiO2 electrode material via aerosol method. Spherical TiO2 nano particles with controllable porosity and surface area were achieved using a low-cost precursor. Carbon compound including carbon black, carbon nanotube and graphene were used to modify the TiO2 material using both aerosol and hydrothermal method. The TiO2/carbon composite performed high capacity, conductivity and better cycliability.
