{"volume":142,"abstract":[{"text":"Rechargeable aqueous Zn-ion energy storage devices are promising candidates for next-generation energy storage technologies. However, the lack of highly reversible Zn2+-storage anode materials with low potential windows remains a primary concern. Here, we report a two-dimensional polyarylimide covalent organic framework (PI-COF) anode with high-kinetics Zn2+-storage capability. The well-organized pore channels of PI-COF allow the high accessibility of the build-in redox-active carbonyl groups and efficient ion diffusion with a low energy barrier. The constructed PI-COF anode exhibits a specific capacity (332 C g–1 or 92 mAh g–1 at 0.7 A g–1), a high rate capability (79.8% at 7 A g–1), and a long cycle life (85% over 4000 cycles). In situ Raman investigation and first-principle calculations clarify the two-step Zn2+-storage mechanism, in which imide carbonyl groups reversibly form negatively charged enolates. Dendrite-free full Zn-ion devices are fabricated by coupling PI-COF anodes with MnO2 cathodes, delivering excellent energy densities (23.9 ∼ 66.5 Wh kg–1) and supercapacitor-level power densities (133 ∼ 4782 W kg–1). This study demonstrates the feasibility of covalent organic framework as Zn2+-storage anodes and shows a promising prospect for constructing reliable aqueous energy storage devices.","lang":"eng"}],"doi":"10.1021/jacs.0c07992","year":"2020","intvolume":"       142","_id":"21240","publication_identifier":{"issn":["0002-7863"]},"author":[{"first_name":"Minghao","full_name":"Yu, Minghao","last_name":"Yu"},{"full_name":"Chandrasekhar, Naisa","last_name":"Chandrasekhar","first_name":"Naisa"},{"last_name":"Kormath Madam Raghupathy","full_name":"Kormath Madam Raghupathy, Ramya","id":"71692","first_name":"Ramya","orcid":"https://orcid.org/0000-0003-4667-9744"},{"first_name":"Khoa Hoang","last_name":"Ly","full_name":"Ly, Khoa Hoang"},{"full_name":"Zhang, Haozhe","last_name":"Zhang","first_name":"Haozhe"},{"first_name":"Evgenia","full_name":"Dmitrieva, Evgenia","last_name":"Dmitrieva"},{"last_name":"Liang","full_name":"Liang, Chaolun","first_name":"Chaolun"},{"first_name":"Xihong","full_name":"Lu, Xihong","last_name":"Lu"},{"full_name":"Kühne, Thomas","last_name":"Kühne","id":"49079","first_name":"Thomas"},{"first_name":"S.
