In Situ Construction of NiFe LDH@MoS 2 Heterostructure with Built‐in Electric Field Coupling Mo Vacancies Promotes Rapid Reaction Kinetics for Chloride Ion Batteries

simultaneously functions as an electron-highway network and a structural buffer that homogenizes interfacial electric fields, thereby steering coordinated charge compensation across heterointerfaces. This work unveils the importance of heterointerface engineering in regulating both ion/electron dynamics for LDH-based energy storage systems, offering a universal design principle for high-performance halogen-ion batteries (HIBs).
