This study fabricates Fine Slag/Ti4O7@TiC hybrids with interfacial dioxygen bridge coupling to optimize oxygen redox dynamics in lithium‐oxygen batteries (LOBs). Lattice distortion from oxygen vacancies and inherent charge repulsion of Ti‐O‐C interfacial coupling reconstruct and refine the surface coordination environment.

ABSTRACT The present work systematically compares the performance differences between two novel homologous materials employed as co‐carbonization agents in the synthesis of mesophase pitch. Low‐cost FCC slurry was used as the raw material, with bio‐tar (BT) and bio‐tar pitch (BTP) as co‐carbonization agents.
