With the widespread use of lithium-ion batteries (LIBs) in recent decades, lithium resources are at risk of depletion. Electrochemical energy storage using LIBs cannot keep pace with socioeconomic development. Therefore, it is necessary to develop electrochemical systems capable of storing large amounts of energy in the future to replace LIBs. As a result of their environmental friendliness, low cost, and high safety, aqueous zinc-ion batteries (AZIBs) are potential replacements for LIBs. Several challenges remain for the commercialization of AZIBs, however, such as the development of high-performance cathodes. In recent years, metal-organic frameworks (MOFs) and related materials have evolved into potential cathode materials for AZIBs due to their high porosities, tunable structures, and multifunctionality. Hence, this review summarizes the latest progress in MOF-based cathode materials for AZIBs. We present and discuss different types of MOF-based electrode materials (vanadium/mangan
Two-dimensional (2D) layered materials have promising prospects for Zn-storage due to their flexible and adjustable interlayer architecture. The strong electrostatic interaction and high diffusion energy barrier, however, lead to slow diffusion kinetics of Zn-ions between the 2D interfaces, limiting its widespread application. Herein, Ti3C2 MXene is introduced into the MoS2 interlayer by the "pillar effect" to assemble a layer-by-layer inter-embedded structure (L-MoS2/Ti3C2), which provides sufficient diffusion channels for Zn-ions. DFT computations and GITT confirm that the L-MoS2/Ti3C2 exhibits superior Zn-ions migration kinetics. Therefore, L-MoS2/Ti3C2 shows excellent long-term cycling stability (75.6% capacity retention after 7000 cycles at 15 A g-1) and glorious high-rate capability (107 mAh g-1 at 20 A g-1). In addition, the practical application of this material is demonstrated by evaluating the performance of L-MoS2/Ti3C2 in flexible quasi-solid-state aqueous zinc io
