Herein, a well-designed electrolyte based on 2 M Zn(CF3SO3)2-0.2 M acrylamide-0.2 M ZnSO4 is proposed. A robust polymer (polyacrylamide)-inorganic (Zn4SO4(OH)6.xH2O) hybrid SEI is in situ constructed on Zn anodes through controllable polymerization of acrylamide and coprecipitation of SO42− with Zn2+ and OH−. For the first time, the underlying SEI composition-property-performance relationship is systematically investigated and correlated. The results showed that the polymer-inorganic hybrid SEI, which integrates the high modulus of the inorganic component with the high toughness of the polymer ingredient, can realize high reversibility and long-term interfacial stability, even under ultrahigh areal current density and capacity (30 mA cm−2~30 mAh cm−2). The resultant Zn||NH4V4O10 cell also exhibits excellent cycling stability. This work will provide a guidance for the rational design of SEI layers in rechargeable aqueous zinc ion batteries. date: 2024-03-25 date_type: published publisher: Wiley official_url: https://doi.org/10.1002/anie.202401987 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2263554 doi: 10.1002/anie.202401987 medium: Print-Electronic lyricists_name: Zhang, Wei lyricists_name: He, Guanjie lyricists_id: WZHAI00 lyricists_id: GJHEX85 actors_name: Flynn, Bernadette actors_id: BFFLY94 actors_role: owner full_text_status: public publication: Angewandte Chemie - International Edition article_number: e202401987 event_location: Germany issn: 1433-7851 citation: Chen, R; Zhang, W; Guan, C; Zhou, Y; Gilmore, I; Tang, H; Zhang, Z; ...
