Currently, the practical application of such batteries is hindered by the poor cycling performance of Zn anodes due to uncontrolled dendrite formation and severe side reactions, although recent reports suggest that these problems can be mitigated through the modification of Zn anodes with metal-based materials.Given that the mechanisms of improving Zn deposition and the structural evolution of metal-based materials have not been systematically reviewed, we herein systematically overview the metal-based materials used to stabilize Zn anodes, starting with a brief summary of the anode working mechanism and the challenges faced by stabilized Zn anodes. Subsequently, the design principles of Zn anodes stabilized by metal-based materials and the related recent progress are reviewed, and the key challenges and perspectives for the future development of such Zn anodes are proposed.展开更多

Among various power supply systems, flexible Zinc-ion energy storage devices have attracted extensive interest due to their cost-effectiveness, high theoretical capacity, superior safety, and environmental friendliness. To achieve flexibility in Zn-ion-based energy storage devices, the design and fabrication of flexible and/or freestanding active electrodes is one of the key issues. MXene as a novel family of two-dimensional (2D) materials shows outstanding integration of metal-like conductivity, abundant active sites, and excellent mechanical properties, which can be promising flexible electrodes for Zn ion storage. This review comprehensively expounds on the progress of reported flexible freestanding MXene-based composite films for different Zn-ion-based energy storage systems including Zn-ion capacitors (ZICs), Zinc-ion batteries (ZIBs), and Zinc-air batteries (ZABs). We also propose the challenges and perspective of improving the electrochemical performance of flexible freestanding MXene-based Zn-ion-based energy storage. This review serves as a guideline to inspire more future endeavors in synthesizing advanced flexible MXene-based electrodes for efficient Zinc ion storage.展开更多
