Abstract
$Li_4Ti_5O_{12}$ (LTO) is an anode material for lithium ion battery, and the cycle performance is very good. The volume change of LTO during insertion and deinsertion of lithium ion is very small, so the cyclibility is very high. In this experiment graphene and CNT was added to increase the low conductivity of LTO which is the weak point of LTO. When graphene was located on the surface of LTO the conductivity did not increase so much because of the nano size LTO. Addition of CNT increased the conductivity because of the formation of the conducting network between LTO particle and the graphene. Carbon material addition was changed before and after the LTO manufacturing, and the capacity and the cyclibility was compared.
