Abstract The stable electrode/electrolyte interface and fast electron/ion transport channel play important roles in boosting the rate performance cycling life of lithium‐ion batteries. Herein, a porous silicon/carbon composite (pSi@PC@MC) is presented by integrating hollow silicon (pSi) with pitch‐derived carbon (PC) dopamine‐derived mesoporous (MC), employing microporous zeolite as source. finite element simulation first reveals stress release effect rigid flexible encapsulation on Si anode for storage. In situ ex characterization results further elucidate that hybrid sp 2 /sp 3 coating greatly enhances liquid/solid stability compatibility electrolyte, well facilitates transmission dynamics, achieving uniform, stable, LiF‐rich SEI film, ultimately improving lithium storage performance. As expected, as‐designed pSi@PC@MC delivers an impressive capability (756.6 mAh g −1 at 6 A ) excellent capacity 1650 after 300 cycles 0.2 . Meanwhile, pSi@PC@MC//NCM811 full‐cell exhibits outstanding (75.8% retention 100 cycles). This study highlights significance rational design effective development fast‐charging Si/carbon anodes.
