Summary: Oxygen evolution reaction (OER) is a crucial half-reaction in water splitting and its slow kinetic process limits the efficiency of electrocatalytic water. Therefore, developing high activity OER electrocatalysts is essential for the advancement of water splitting. Zeolitic imidazolate framework-67 (ZIF-67) based compositions, with nitrogen-containing ligands, highly dispersed Co active sites, abundant Co-N bonds, tunable pore structure, and large surface area, have received extensive attention in the preparation of non-noble electrocatalysts for OER. Various modification methods, such as coordination environment optimization, morphology engineering, heteroatom incorporation, heterostructure construction, and hybridization, have been developed to construct ZIF-67 based electrocatalysts and regulate their active sites. This article summarizes the advanced modulation strategies on ZIF-67 based compositions for OER performance enhancement, highlighting the synthetic approaches, engineering principles, and catalytic mechanisms. The current challenges and prospects for developing the next-generation OER electrocatalysts are also discussed.

Summary: This work reports the construction of zinc-based zeolite imidazole framework (ZIF-8) microrings through an anisotropic growth-etching route. The method involves the deposition of ZIF-8 crystals on the edges of leaf-like ZIF-L nanosheets with coordinatively unsaturated Zn2+ and subsequent selective etching of alkaline unstable ZIF-L. Additionally, functional carbon materials with a ring-like structure can be prepared by pyrolysis of ZIF-8 microrings, exhibiting improved performance in oxygen reduction reaction. These findings may pave the way for the design of MOFs with sophisticated micro/nanostructures.

Summary: Rechargeable aqueous zinc-ion batteries (ZIBs) are a promising technology for grid-scale energy storage systems. However, the growth of zinc dendrites and side reactions on the anodes have hindered practical applications. In this study, the relationship between zinc dendrite growth and internal stress accumulation during zinc plating is revealed. A zinc metal anode with patterned micro-grooves is proposed to release plating-induced stress and inhibit dendrite growth. Coupled with a Nafion film coating, this anode shows stable cycling performance, low electrochemical polarization, and voltage hysteresis in deep discharge/charge performance. The proposed strategy is also successfully applied to a Zn|MnO2 flexible pouch cell, demonstrating impressive capacity, electrochemical stability, and mechanical flexibility. This study provides valuable insights into the design of reversible aqueous zinc-ion batteries.

Summary: The implementation of high-safety Li metal batteries (LMBs) requires stable and safe electrolytes. Solid-state electrolytes (SSEs) are considered advantageous due to their properties; however, they suffer from low stability at the Li/electrolyte interface and uncontrolled Li dendrites growth, causing capacity degradation. To overcome these issues, a polymer electrolyte with self-healing capacity is introduced, which allows high Li+ transport, wide electrochemical window, and self-reconstruction of defects and fatigue cracks. The equipped Li|LFP batteries exhibit high initial specific capacity and excellent capacity retention, indicating the potential for developing safe and stable LMBs.

Summary: Solid polymer electrolytes (SPEs) are safer than traditional organic liquid electrolytes for lithium metal batteries (LMBs), but their low ionic conductivity at room temperature is a limitation. Adding nonflammable ionic liquids (ILs) as plasticizer agents can suppress crystallinity. Among the cations investigated, EMIM+ showed the best reversible Li+ intercalation/deintercalation behavior due to its superior cationic solvation, highest ion conductivity, and lowest viscosity. Batteries based on the optimized EMIM+-encapsulated ionogel electrolyte demonstrated stable cycling performance.
