Summary: Rechargeable aqueous zinc metal batteries have received great attention due to their safety and low cost. However, the growth of zinc dendrites in aqueous electrolytes severely limits the lifespan of these batteries. In this study, a strategy was proposed to enhance the activity of zinc-alloying sites by introducing a small amount of polar organic additive in the electrolyte, forming a molecular crowding layer to prevent parasitic water reduction during zinc deposition. This multifunctional interfacial structure allows stable cycling of the zinc anode and can potentially improve the performance of other aqueous metal batteries.

Summary: In this work, a C@VO2 composite was constructed via anti-aggregation growth and hierarchical porous carbon encapsulation to improve the electrochemical performance of aqueous zinc-ion batteries (AZIBs). The morphology and pore structure of the composite can be regulated by tuning the adding amount of glucose. The C@VO2-3:3 composite delivered a high capacity of 281 mAh g-1 at 0.2 A g-1 as a cathode for AZIBs, and exhibited remarkable rate capability and cyclic stability. The evolution of crystal structure, valence state, and transport kinetics upon cycling was also investigated. The synergistic effect of anti-aggregation morphology and hierarchical porous carbon encapsulation in the C@VO2 composite enhances the ion accessible site and transport kinetics, resulting in superior storage performance. This design concept can be applied to other types of electrode materials, accelerating the development of high-performance AZIBs.

Summary: A unique voltage and solvation environment coordinated control strategy was developed to unlock the MXene derived VNxOy/C heterostructure as robust host applied for aqueous zinc-ion batteries. The introduction of hydrophilic polyethylene glycol (PEG) into electrolyte enables tailoring the solvation environment, forming the proton shielding to eliminate the blocking effect of by-products on interfacial transport kinetics and storage reversibility of the electrode, thus realizing controllable Zn2+-dominant insertion/extraction mechanism. The VNxOy/C electrode under the coordinated control of voltage and solvation environment enables achieving a significantly enhanced rate capability and ultralong cycle lifespan.

Summary: This study presents a multiscale interface structure-integrated modulation concept to enhance the storage kinetics of VSe2-x · n H2O host for zinc ion storage. The intercalation of H2O and the modulation of selenium vacancy can enhance the capture ability and reduce the diffusion barrier of zinc ions. It is found that the storage mechanism involves interfacial adsorption and intercalation pseudocapacitance. The cathode exhibits excellent storage performance at a wide temperature range (-40-60 degrees C) in aqueous and solid electrolytes. High specific capacity, energy density, and power density are achieved at different temperatures. This work extends the interfacial storage limit of layered TMDs and enables the construction of all-climate high-performance Zn-ion batteries.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
