Summary: The degradation and poor conductivity of the cobalt-zinc oxide structure during charge and discharge are overcome by the ZnCo2O4@carbon nanofiber composite obtained through electrospinning, annealing, and low-temperature oxidation. The evenly dispersed active sites of ZnCo2O4 inside the carbon nanofibers prevent aggregation and improve electrical conductivity. The stable nanofibrous structure contributes to the superior lithium ion storage capacity of the composite as an anode electrode.

Summary: The commercialization of high-energy-density lithium-sulfur batteries depends on the development of a high-sulfur-loading cathode with high electrochemical utilization and stability in lean-electrolyte cells. However, current cell designs often lead to slow conversion reactions and polysulfide diffusion, resulting in poor performance. In this study, a new core-shell polysulfide/carbon cathode design was introduced, which showed improved redox kinetics and charge transfer and stabilized the electrochemical reaction. This design enabled a lean-electrolyte lithium-sulfur cell with a high sulfur loading to achieve high capacity and long-term cyclability.

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.
