Summary: Rechargeable aqueous Zn-MnO2 batteries are promising for large-scale energy storage, but the issues of phase transition and structural collapse of MnO2 cathodes still exist. Intercalation of layered MnO2 has become the mainstream strategy, but the characteristics of Mn octahedral layers are often neglected. In this study, the researchers elucidate the impact of layer symmetry on the electrochemical performance of birnessites. The hexagonal birnessite with stabilized Mn(II) ions exhibits better charge storage performance than its monoclinic precursor, due to the generation of layer cation vacancies, interlayer Mn(II) ions, and nanosized morphology. The work provides a new approach for designing high-performance layered cathode materials.

Summary: In this study, hydrogel surfaces with different cross-linkages were prepared by pH-modulating the coordination pattern of Fe3+ and catechol. It was found that increasing cross-linkages decrease the ice nucleation temperature. Further analysis revealed that ice nucleation could be regulated by modulating the interfacial water of the hydrogel surfaces with different cross-linking degrees. The study elucidates the mechanism of ice nucleation regulated by interfacial water in soft matter and proposes a new method for preparing ice nucleation-regulated materials.
