Carbon nanotubes with high electrical conductivity, thermal conductivity, outstanding mechanical strength, and unique morphology and structure, are used for improving the performance of lithium-ion batteries. This paper reviews the latest progress in the study of carbon nanotubes as conductive additives, matrices of composite electrode materials, and current collectors in lithium ion batteries. The emphasis is to introduce the update methods of applying carbon nanotubes as conductive additives and composite matrices in the electrode materials, as well as the effects on the capacity, rate capacity and cycle life. There are also some challenges for using carbon nanotubes widely in lithium-ion batteries, such as reducing the production costs, inventing composite technique for industrial manufacturing, and improving the dispersion properties.
