Dual‐Functional V2C MXene Assembly in Facilitating Sulfur Evolution Kinetics and Li‐Ion Sieving toward Practical Lithium–Sulfur Batteries

S nucleation and decomposition reaction kinetics owing to the scale effect; and (iii) the VC can regulate the dynamic behavior of Li-ions and thus stabilize the lithium plating/stripping effectively on account of the unique ion-sieving effect.
