Summary: In this study, we propose a solvation tuning strategy by utilizing molecular steric effect to create a bulky coordinating structure in battery electrolyte design. The designed electrolyte generates an inorganic-rich solid electrolyte interphase (SEI) and cathode-electrolyte interphase (CEI), leading to excellent compatibility with both Li metal anodes and high-voltage cathodes. Under an ultrahigh voltage of 4.6 V, Li/NMC811 full-cells (N/P = 2.0) hold an 84.1% capacity retention over 150 cycles and industrial Li/NMC811 pouch cells realize an energy density of 495 Wh kg-1. This study provides innovative insights into Li+ solvation tuning for electrolyte engineering and offers a promising path toward developing high-energy Li metal batteries.

Summary: A novel air cathode for rechargeable zinc-air batteries (ZABs) is designed and synthesized by finely tuning the fluorinated nanopores of a covalent organic framework (COF). The COF nanosheets decorated with fluorinated alkyl chains provide well-defined O-2-transport channels and significantly enlarge the area of three-phase boundaries, promoting mass-transfer. The ZABs based on the COF-modified air cathode exhibit a small charge/discharge voltage gap, high peak power density, and stable cyclability. This work provides a feasible approach for the design of high-performance ZABs and expands the new application of COFs.
