Covalent organic frameworks (COFs) have attracted considerable interest in the field of rechargeable batteries owing to their three-dimensional (3D) varied pore sizes, inerratic porous structures, abundant redox-active sites, and customizable structure-adjustable frameworks. In context metal-ion batteries, these materials play a vital role electrode materials, effectively addressing critical issues such as low ionic conductivity, limited specific capacity, unstable structural integrity....
Lithium metal batteries (LMBs), with high energy densities, are strong contenders for the next generation of storage systems. Nevertheless, unregulated growth lithium dendrites and unstable solid electrolyte interphase (SEI) significantly hamper their cycling efficiency raise serious safety concerns, rendering LMBs unfeasible real-world implementation. Covalent organic frameworks (COFs) derivatives have emerged as multifunctional materials significant potential addressing inherent problems...
Abstract In this work, self‐derivation and surface reconstruction strategies are innovatively introduced into the synthetic route of metal complex‐derived catalysts. The in situ grown nanorod arrays Ni‐based complex prepared by a simple rapid ligand chelation reaction. Furthermore, highly active heterogeneous electrocatalysts developed mild‐temperature calcination. Attributed to maintained morphology dispersed Ni/Ni(OH) 2 heterojunction sites, as‐prepared electrode exhibits superior hydrogen...
The practical application of sulfur (S) cathodes in lithium-sulfur (Li-S) batteries is hindered by the shuttling soluble lithium polysulfides (LiPSs) and sluggish redox kinetics. Addressing these challenges requires advanced catalytic host materials capable trapping LiPSs accelerating Li-S reactions. However, single-site catalysts struggle to effectively mediate complex multi-step multi-phase conversion processes. In this study, we present a novel dual-site catalyst, featuring nickel single...
