However, thus far, the conventional hydrothermal/solvothermal route for this nanoconfinement has been restricted to its uncontrollable phase structure and the difficulty on the multiple cation co-confinement simultaneously. Herein, we reported a general, supramolecular self-assembly of ultrathin V2O5 nanosheets using various unitary cations including Na+, K+, Mg2+, Ca2+, Zn2+, Al3+, NH4+ and multiple cations (NH4+ + Na+, NH4+ + Na+ + Ca2+, NH4+ + Na+ + Ca2+ +Mg2+). The unitary cation confinement results in a remarkable increase in the specific capacity and Zn-ion diffusion kinetics, and the multiple cation confinement gives rise to superior structural and cycling stability by multiple cation synergetic pillaring effect. The optimized diffusion coefficient of Zn-ion (7.5×10-8 cm2 s-1) in this assembly series surpasses most of the V-based cathodes reported up to date. Density functional theoretical (DFT) simulation further reveals a declined Zn-ion diffusion barrier by cation confinement due to a significantly weakened interaction between Zn2+ and the dangling oxygen atom of V2O5. Our work develops a novel multiple-cations nanoconfinement strategy toward high-performance cathode for aqueous battery. It also provides new insights into the guest cation regulation of zinc-ion diffusion kinetics through a general, supramolecular assembly pathway. description_type: abstract lang: und ## Creator - name: Yang Liu role: author - name: Chengjie Lu role: author - name: Yunting Yang role: author - name: Wenshu Chen role: author - name: Fei Ye role: author - name: Hongliang Dong role: author - name: Yuping Wu role: author - name: Renzhi Ma role: author orcid: https://orcid.org/0000-0001-7126-2006 - name: Linfeng Hu role: author orcid: https://orcid.org/0000-0002-0640-508X ## Contact agent ## Publisher organization: Wiley ## Managing organization ## Keyword - subject: Nanosheets schema: not_defined - subject: Battery schema: not_defined ## Rights - description: 'This is the peer reviewed version of the following article: Multiple Cations Nanoconfinement in Ultrathin V2O5 Nanosheets Enables Ultrafast Ion Diffusion Kinetics Toward High-performance Zinc Ion Battery, which has been published in final form at https://doi.org/10.1002/adma.202312982.
