Silicon, as one of the most promising candidates for next‐generation lithium‐ion batteries (LIB), is intensively researched. Although various efforts is devoted to addressing major issues of silicon anodes, the intrinsic low conductivity and tremendous volume change still hinder its further real practical applications. Constructing carbon–silicon hybrid materials is regarded as the powerful strategy to improve the electrochemical lithium storage performance of silicon, in which the component dimensional variations and the dimensional hybridization way play critical roles in improving lithium storage performances. Carbon–silicon hybrids are classified herein, based on dimensional variations of silicon and carbon, and the latest representative progresses on carbon–silicon hybrids following such classifications are elaborated, with emphasis on the involved dimensional design formulas, the resultant synergistic effects, and the potential in performance enhancement. To conclude, the future directions and prospects in the field are discussed, providing insight into the rational design and scalable construction of advanced carbon–silicon hybrids and electrode systems for practical LIB.
