Abstract Solid‐state zinc ion batteries (ZIBs) hold great potential for sustainable and high‐safety reserves. However, the advancement of solid‐state ZIBs is constrained by shortage reasonable electrolytes (SSE) with abundant hopping sites, effective hydrogen evolution reaction (HER) inhibition, favorable interfacial compatibility. Herein, hydrogen‐bonded organic framework (HOF) CAM‐Ag Zn 2+ sites developed as SSE ZIBs. Taking advantage short‐distance conduction pathways crystal transformation through incorporating Ag−N coordinate bonds, achieves a significant ionic conductivity 1.14 × 10 −4 S cm −1 at room temperature superior transference number 0.72. An bonds network effectively inhibits initiation HER subsequent generation by‐products. Moreover, rapid kinetics facilitated inhibition dendrite growth, promoting uniform distribution. displays an extensive electrochemical stability range 0–2.66 V remarkable compatibility, enabling stable plating/stripping ≈1000 h 1 mA −2 . Consequently, SSE‐based achieve specific capacity 315 mAh g only 1.5% decrease in capacitance after 24 h. The proposed HOF‐based pathway advancing high‐performance

A magical heterostructures of M-PBAs (M = Co, Cu, and Zn) encapsulated by V-PBA have been successfully obtained a facile one-pot coprecipitation method based on the difference in binding energies between these metal ions ligands, nucleation rates different M-PBAs. Hence, due to multiple redox pairs, open frameworks, ordered channels, synergistic effect two components, VM-PBAs tested as cathodes aqueous zinc-ion batteries (AZIBs). To further inhibiting hydrolysis vanadium collapse PBAs structures, series glycerol-water hybrid electrolyte with content glycerol were designed. Benefiting from hydroxyl groups, appropriate viscosity accurate proportion glycerol, as-assembled AZIBs VMn-PBAs cathode can exhibit excellent cycling performance (∼73% capacity retain stable capacity) after 1000 cycles. This work provides sight preparation nanomaterials strategy improve stability rate PBAs-based AZIBs.
