Summary: The lithiophilic vertical cactus-like framework (LVCF) derived from a Zn/Cu-based coordination polymer through in situ chemical etching of Cu foam demonstrates improved safety and electrochemical performance of Li metal anodes. The special structure of LVCF includes lithiophilic nitrogen-containing functional groups, ZnO quantum dots, and in situ grown carbon nanotubes, which help to avoid harmful Li dendrite formation. With enhanced lithiophilicity, reduced local current density, and alleviated volume expansion, LVCF shows stable Coulombic efficiency and improved cycle life.

Summary: Coordination polymers (CPs) with multiple redox-active sites have great potential as rechargeable lithium batteries due to their adjustable composition, pore structure, crystalline nature, and easy synthesis. The crystalline structures provide abundant accessible redox-active sites and three-dimensional channels for rapid ion transport. This review summarizes the design strategies of CP-based materials for lithium-ion storage and ion transport in rechargeable lithium batteries. The improved electrochemical performance of CPs in lithium batteries is closely related to favorable working mechanisms, synergistic redox-active reactions, addition of conductive molecules, and well-designed porous structures or morphologies. The opportunities and challenges of applying CPs to lithium-ion storage and ion transport are also discussed.

Summary: This study reports a method for achieving organized assembly structures with high complexity and adjustable functionalities. A discotic benzene-1,3,5-tricarboxamide (BTA) ligand is allowed to coordinate with lanthanide (Ln) ions to form a multi-BTA coordination cluster, which further stacks into fibers with hydrogen bonds. The fibrous morphology, size, packing unit, and growth process are investigated, and tunable luminescence and magnetic relaxation properties are achieved by selecting different lanthanides. This hierarchical self-assembly is made possible by the special structure of the BTA-like building block, and the use of lanthanide coordination leads to materials with metal-derived optical and magnetic properties.

Summary: Hierarchical Co1-xS/MnS/NC nanowires were prepared successfully through a simple hydrothermal reaction and subsequent annealing of one-dimensional coordination polymer precursors. The heterostructure nanowires not only act as a buffer for volume expansion during charging and discharging but also significantly enhance electronic conductivity, leading to improved rate performance and cycling stability. The nanowires maintain a high capacity of 612.9 mA h g(-1) after 100 cycles at 0.5 A g(-1) and 544.6 mA h g(-1) after 200 cycles at 1.0 A g(-1) for SIBs.
