Silicon (Si) has been considered as the most promising anode material for overcoming the theoretical capacity limit of a carbonaceous anode. Since the implementation of nanotechnology on Si anode, the significant progress has been made as addressing severe volume change during (de)lithiation. However, the practical application of Si anodes in commercial lithium-ion batteries (LIBs) has been still stagnant. Nowadays, with the drastic increase in energy demands of diverse industries, co-utilization of Si and graphite has resurfaced as the commercially viable method for realizing high energy. Herein, we highlight the necessity for the co-utilization of graphite and Si in terms of the commercialization, and carefully review the development of graphite/Si anodes. Representative Si anodes implemented in the graphite-blended electrode are covered and a variety of strategies for building graphite/Si composites are organized according to their synthetic methods. Particularly noteworthy, the critical factors for the co-utilization of graphite and Si are systematically presented. Finally, we provide insightful suggestions with regard to the co-utilization of graphite and Si for the commercialization.
