There are abundant coal source in Shanxi province. How to utilize effectively this resource with high additional value has gained great attention and become an important strategy in Shanxi province. This project aims to the design, preparation and energy-storage performance of mesocarbon microbeads (MCMB) for power lithium-ion batteries based on the abundant coal tar pitch in Shanxi. The processing parameters, formation mechanism and regularity of MCMB from coal tar pitches via the one-step emusion-polycondensation in an inert gas atmosphere will be revealed, and the effects of additives such as carbon nanotubes and graphene on the polycondensation of coal tar pitch, morphology, structure and Lithium-storage property of MCMB will be investigated in detail. New approach for the production of mesocarbon microbeads with high specific capacity, high-rate performance and long cycle ability will be developed for the application of power Lithium-ion batteries. The key scientific problems in the preparation of carbon materials from coal tar pitches will be resolved. These research results will be beneficial for the utilization with high efficiency and high value of coal tar pitch resource in Shanxi, and improve the processing techniques for coal tar pitch.
