Abstract Aqueous Zn 2+ -ion batteries (AZIBs), recognized for their high security, reliability, and cost efficiency, have garnered considerable attention. However, the prevalent issues of dendrite growth parasitic reactions at electrode interface significantly impede practical application. In this study, we introduced a ubiquitous biomolecule phenylalanine (Phe) into electrolyte as multifunctional additive to improve reversibility anode. Leveraging its exceptional nucleophilic characteristics, Phe molecules tend coordinate with ions optimizing solvation environment. Simultaneously, distinctive lipophilicity aromatic amino acids empowers higher adsorption energy, enabling construction protective interphase. The hydrophobic benzene ring ligands act cleaners repelling H 2 O molecules, while hydrophilic hydroxyl carboxyl groups attract homogenizing flux. Moreover, preferential reduction prior facilitates in situ formation an organic–inorganic hybrid solid interphase, enhancing interfacial stability Consequently, Zn||Zn cells display improved reversibility, achieving extended cycle life 5250 h. Additionally, Zn||LMO full exhibit enhanced cyclability retaining 77.3% capacity after 300 cycles, demonstrating substantial potential advancing commercialization AZIBs.

Abstract The composite solid electrolyte, which combines the advantages of inorganic conductors and organic polymer electrolytes, has become a crucial strategy for construction solid‐state batteries. However, physical deposition agglomeration traditional fillers seriously affect their structural uniformity ion transport performance, uniform stable electrolytes is still an insurmountable challenge. Herein, in situ hybrid crosslinking polymerization TiO 2 nanoparticles proposed highly (NHCPE) with ultrahigh ionic conductivity 1.74 × 10 −3 S cm −1 at 25 °C, high lithium‐ion transference number 0.725. These properties enable composed lithium symmetric battery to be stably deposited/plating off 0.5 mA −2 more than 1000 h. Moreover, assembled LFP|PDOL@nanoTiO |Li exhibits superior specific discharge capacity 142.6 mAh g 1 C retention rate 90% after cycles. PDOL@nanoTiO NHCPE greatly inhibits defects easy solves problems decomposition, low thermal stability, poor safety polyether opens up new way design industrial application high‐stability electrolytes.

Abstract The growing environmental pollution issues and continuous energy dilemma call for high‐performance storage systems (ESSs). While the inevitable safety concerns appear restrict application of lithium‐ion batteries in large‐scale ESSs. Contrastively, zinc ion (ZIBs) attract increasing attention due to inherent advantages high safety, low cost, friendliness. However, poor stability reversibility Zn anodes bring severe difficulty its practical application. Considerable efforts are devoted anode modification, such as electrolyte adjustment, interfacial engineering, structure design, but there is still a fuzzy field concerning reaction process, regulation mechanism, modified effect. Reviewing history, development various electrodes greatly depends on breakthrough advanced characterization technologies, while summarizations technological advances deficient. Hence, this review concentrates recent progress techniques related strategies protection. information especially highlighted that each technique can offer crucial or auxiliary role they play proving specific issues. Furthermore, opinions current limitations future directions common also discussed detail, aiming give comprehensive perspective designing anodes.
