ABSTRACT
The Li-ion batteries (LIB) technology commercialized by Sony in 1991 is based on a low-voltage Li intercalation-deintercalation process in carbonaceous material. Advances in carbon nanomaterials have provided the opportunity to design and form novel energy storage materials for the next-generation high-performance LIBs with higher capacity and longer cycle life. This chapter introduces three kinds of carbon materials, traditional carbon, carbon nanotubes, and graphene as the anode materials in LIBs. The incorporation of carbon nanomaterials into active materials, such as metals and metal oxides, is a generally efficient avenue for broadening and enhancing the performance of LIBs. Carbon nanotubes have been employed as the conductive additives to form conductive networks within the cathode materials to increase the increase the capacity, charge/discharge rate, and the lifetime. Almost all of the reported performance of graphene anode materials is significantly higher than that of graphite.
