Abstract An ideal porous adsorbent toward uranium with not only large adsorption capacity and high selectivity but also broad applicability even under rigorous conditions is highly desirable still extremely scarce. In this work, a adsorbent, namely [NH 4 ] + [COF‐SO 3 − ], prepared by ammoniating SO H‐decorated covalent organic framework (COF) enables remarkable performance for extraction. Relative to the pristine COF (COF‐SO H) of 360 mg g −1 , ammoniated counterpart affords ultrahigh...
Element doping/substitution has been recognized as an effective strategy to enhance the structural stability of layered cathodes. However, abundant substitution studies not only lack a clear identification sites in material lattice, but rigid interpretation transition metal (TM)-O covalent theory is also sufficiently convincing, resulting proposals being dragged into design blindness. In this work, taking Li1.2Ni0.2Mn0.6O2 prototype, intense correlation between "disordered degree" (Li/Ni...
Prussian blue analogues (PBAs) are appealing active materials for post-lithium electrochemical energy storage. However, PBAs not generally suitable non-aqueous Li-ion storage due to their instability upon prolonged cycling. Herein, we assess the feasibility of with various lithium content We determine crystal structure lithiated via neutron powder diffraction measurements and investigate influence water on structural stability migration through operando X-ray bond valence simulations....
Cathode materials are critical for Na-ion batteries while facing challenges due to the instability of structure and interfaces. In this work, we propose a strategy achieve an in situ plastic-crystal Na3–3xAlxPO4 coating bulk Al doping O3-NaNi0.4Fe0.2Mn0.4O2 cathode through simple one-step method. exhibits high ion transport performance its unique "paddle-wheel" mechanism. The formed could consume residual alkali compounds induce formation Na-deficient phase, thus leading enhanced Na+...
The anionic redox reaction (ARR) is a promising charge contributor to improve the reversible capacity of layered-oxide cathodes for Na-ion batteries; however, some practical bottlenecks still need be eliminated, including low retention, large voltage hysteresis, and rate capability. Herein, we proposed high-Na content honeycomb-ordered cathode, P2-Na5/6[Li1/6Cu1/6Mn2/3]O2 (P2-NLCMO), with combined cationic/anionic redox. Neutron powder diffraction X-ray P2-NLCMO suggested P2-type stacking...
Understanding the interfacial hydrogen evolution reaction (HER) is crucial to regulate electrochemical behavior in aqueous zinc batteries. However, mechanism of HER related solvation chemistry remains elusive, especially time-dependent dynamic bond (H-bond) under an electric field. Herein, we combine situ spectroscopy with molecular dynamics simulation unravel structure. We find two critical change processes involving Zn-electroplating/stripping, including initial double layer establishment form H
Abstract Na‐ion batteries (NIBs) are promising for grid‐scale energy storage applications. However, the lack of Co, Ni‐free cathode materials has made them less cost‐effective. In this work, Mg 2+ is successfully utilized to activate oxygen redox reaction in earth‐abundant Fe/Mn‐based layered cathodes achieve reversible hybrid anionic and cationic capacities. A high first charge capacity ≈210 mAh g −1 with balanced charge–discharge efficiency achieved without O‐loss, showing a cost $2.02 kWh...
Abstract Stable solid electrolytes are essential to high-safety and high-energy-density lithium batteries, especially for applications with high-voltage cathodes. In such conditions, may experience severe oxidation, decomposition, deactivation during charging at high voltages, leading inadequate cycling performance even cell failure. Here, we address the limitation of halide by introducing local lattice distortion confine distribution Cl − , which effectively curbs kinetics their oxidation....
Air sensitivity remains a substantial barrier to the commercialization of sodium (Na)-layered oxides (NLOs). This problem has puzzled community for decades because complexity interactions between air components and their impact on both bulk surfaces NLOs. We show here that water vapor plays pivotal role in initiating destructive acid oxidative degradations NLOs only when coupled with carbon dioxide or oxygen, respectively. Quantification analysis revealed reducing defined cation competition...

Phase transformation is an effective means to increase the ductility of a material. However, even for commonly observed face-centered-cubic hexagonal-close-packed (fcc-to-hcp) phase transformation, underlying mechanisms are far from being settled. In fact, different pathways have been proposed, especially with regard nucleation hcp at nanoscale. CrCoNi, so-called medium-entropy alloy, fcc-to-hcp has long anticipated. Here, we report in situ loading study neutron diffraction, which revealed...
