While sufficient water promotes cathodic reaction kinetics and capacity, excessive water activity triggers parasitic reactions and electrochemically inactive byproducts at the Zn anode. However, conventional homogeneous hydrogel polymer electrolytes (GPEs) fail to satisfy these conflicting interfacial requirements. Here, we report a gradient-structured Janus GPE, achieved by dissolving acrylonitrile, a hydrophobic monomer with very low water miscibility, into an aqueous electrolyte using the Hofmeister effect. Using two substrates with contrasting polar mismatches, this strategy yields a Janus GPE with different hydrophilicities on its two surfaces and a gradient porous structure. When implemented in AZMB pouch cells, the Janus GPE delivers 97.7% capacity retention after 250 cycles in the pristine state and 92.6% retention relative to the pristine initial capacity over 400 cycles under folding. This performance stems from its asymmetric architecture: The more hydrophilic surface facing the cathode provides a water-rich pathway for Zn<sup>2+</sup> transport and cathodic kinetics, while the less hydrophilic surface facing the Zn anode lowers water activity, suppresses parasitic reactions, and preserves interfacial integrity during bending. Overall, the Janus GPE establishes a bend-resilient interfacial design for flexible AZMBs, simultaneously advancing cathode utilization and Zn anode stability.</div></div>","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"92 ","pages":"Article 105596"},"PeriodicalIF":19.3,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149214308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work proposes an electrochemically constrained residual-bias compensation dual extended Kalman filter (RBC-DEKF) with uncertain-initialization commissioning. A thermal control-oriented parameter-grouped single-particle model (CPG-SPMT) provides paired-electrode dynamics and terminal-voltage prediction, while a separately configurable voltage-discrepancy state accommodates systematic residuals. When the initial SOC is uncertain, residual adaptation is suspended over a verified-healthy startup window.
