Aqueous rechargeable zinc ion batteries (ARZIBs) represent a promising technology for safe and scalable energy storage, yet their practical development is hindered by significant challenges in cathode stability and kinetics. While interfacial engineering is recognized as a key strategy, a systematic framework to deconstruct and compare the diverse interaction mechanisms across material families is needed. This review addresses this need by analyzing recent progress in MXene composite cathodes through a unique dual‐framework perspective, focusing on interfacial bonding strength (weak vs. strong) and spatial integration geometry (surface‐confined vs. interlayer‐embedded). This approach provides a unified lens to elucidate distinct structure‐performance relationships across vanadium‐based, manganese‐based, and other cathode materials. The analysis clarifies that the deliberate construction of strong chemical coupling at the interface is a decisive factor for achieving superior cycling stability and high‐rate capability. More importantly, we further elucidate the evolving roles of MXenes as active hosts and as precursors for MXene‐derived cathodes. Finally, the review synthesizes an integrated roadmap, emphasizing the synergistic advancement of interface design, synthesis, characterization, and application to guide the future development of durable and high‐performance ARZIBs.
