Summary: This study reports a stretchable, supertough, and self-extinguishing polyurethane elastomer by introducing dynamic pi-pi stacking motifs and phosphorus-containing moieties. The elastomer exhibits a large break strain and a record-high toughness, which arises from its dynamic microphase-separated microstructure resulting in increased entropic elasticity and strain-hardening at large strains. The elastomer also shows a self-extinguishing ability due to the presence of phosphorus-containing units and pi-pi stacking interactions. The study demonstrates its promising applications as a reliable and recyclable substrate for strain sensors.

Summary: Lithium-ion batteries (LIBs) are dominant in the new energy industry due to their excellent performance. The microstructures of LIB materials greatly influence their performance. Weak molecular interactions, such as hydrogen bonds, inside LIBs significantly improve their mechanical strength, Li+ transport rate, and intrinsic stabilities. This review summarizes the correlation between hydrogen bond formation and the properties of LIB components, and discusses how hydrogen bond formation affects component performance. It also provides prospects for combining hydrogen bonds with LIB components in future design.

Summary: Ni-rich layered oxides LiNixCoyMnzO2 (NCM, x + y + z = 1, x >= 0.8) are widely used as cathode materials for lithium-ion batteries due to their high capacity and moderate cost. However, the intergranular cracks caused by anisotropic volume changes in the deeply delithiated state limit their large-scale application. To address this issue, a core-shell structure composed of LiNi0.6Co0.2Mn0.2O2 (NCM622) shell and LiNi0.9Co0.05Mn0.05O2 (NCM9055) core is proposed. This unique structure effectively inhibits intergranular crack formation and improves the cycling stability of the cathode.

Summary: An overcrowded electrolyte composed of 1,4-dioxane additive is reported to inhibit the hydrogen evolution reaction and decrease water activity by disrupting the water-hydrogen bonding network. Additionally, a dense hydrophobic Li2CO3 coating layer is formed on the surface of the TiNb2O7 anode material using supercritical fluid CO2 technology, effectively blocking direct contact between electrolyte and electrode. The synergistic effect of these two aspects leads to suppressed hydrogen evolution and enhanced interface stability, resulting in a high initial coulomb efficiency (95%) and capacity retention rate (92%) of LiMn2O4/TiNb2O7 full cells over 500 cycles at 1 C rate.

Summary: Due to their high energy density and environmental friendliness, lithium-ion batteries (LIBs) have been widely used in electric vehicles, energy storage systems, and other devices. However, the traditional LIBs with liquid electrolytes (LEs) pose safety hazards. In order to achieve higher safety and energy density, researchers are exploring the use of solid-state electrolytes (SSEs) instead. This review comprehensively summarizes the behaviors, properties, and mechanisms of interfaces in all-solid-state lithium batteries with various sulfide SSEs, as well as recent research progress on characterization methods and designs to stabilize interfaces. Outlooks, challenges, and possible interface engineering strategies are also discussed.

Summary: Converting CO2 into carbon materials offers a solution to both environmental and energy issues, but low-carbon and energy-efficient conversion remains a challenge. In this study, a time-saving and energy-efficient strategy is reported for converting CO2 into carbon materials by reacting CO2 with Mg(AlH4)2 in a matter of seconds. The graphitization degree and pore structure of the synthesized carbon materials are found to be regulated by CO2 pressure, and the highly graphitized carbon exhibits high capacity and long cycle life for lithium storage applications.

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.
