Abstract The formation of inactive sodium on the substrate is considered to be a critical cause capacity decay in anode‐free batteries (AFSBs), but its mechanism has been insufficiently understood. Herein, for first time, it revealed that inability provide an efficient electron transport pathway stripping due crystal mismatch and weak lattice forces between intrinsic AFSBs. Therefore, indium coating strategy offers favorable matching force with proposed. Sodium can uniformly grow indium‐modified substrates low nucleation barriers, without shedding, this modulating effect sustained over extended cycling periods. Ultimately, pouch‐type AFSBs assembled Na 4 Fe 2.91 (PO ) 2 (P O 7 (NFPP) cathode (≈18 mg cm −2 mass loading) copper foil exhibit retention 78.3% after 320 cycles at 2C rate, whereas bare only less than 60 times. Most importantly, proposed work offer lattice‐ atomic‐scale insights design advanced

Abstract The transition to renewable energy sources has elevated the importance of SIBs (SIBs) as cost-effective alternatives lithium-ion batteries (LIBs) for large-scale storage. This review examines mechanisms gas generation in SIBs, identifying from cathode materials, anode and electrolytes, which pose safety risks like swelling, leakage, explosions. Gases such CO 2 , H O primarily arise instability side reactions between electrode electrolyte, electrolyte decomposition under high temperatures or voltages. Enhanced mitigation strategies, encompassing design, buffer layer construction, material optimization, are deliberated upon. Accordingly, subsequent research endeavors should prioritize long-term high-precision detection bolster performance thereby fortifying their commercial viability furnishing dependable solutions storage electric vehicles.

Abstract Uncontrolled dendrite growth leads to poor cycling performance and potential safety hazards in high‐energy metal resource‐rich (Na/Mg) batteries. Herein, a polar Nylon 6‐cellulose acetate (NCA) separator is designed regulate electrolyte solvation structure electrode–electrolyte interface for dendrite‐free Na/Mg The different dipole interactions between separator's groups (CONH, COOR, ROR, OH) anhydride/ether from ester/ether solvents ensure the universality various electrolytes. In sodium batteries, groups‐constructed confined space within NCA exhibits competitive coordinate with ethylene carbonate‐EC, diethyl carbonate‐DEC, fluoroethylene carbonate‐FEC, which induces an anion‐dominated Na + (NCA: CN solvent ‐3.83, polypropylene: ‐6.47). Then, induced concentration‐enhanced PF 6 − derives NaF‐rich solid interphase high electronic insulation, against owing leakage. Moreover, homogeneous distribution caused by cloud overlap (δ O ↔ δ H ) EC/DEC/FEC enables fast well‐distributed deposition.
