Summary: Graphite is the most popular anode material for lithium-ion batteries due to its high reversibility and stable cycling performance. This study proposes a facile approach to integrate functional metal oxides on the surface of natural graphite (NG) through a surface-coating technique and a crystallization process, which improves the charging performance of graphite. The metal oxides play crucial roles in stabilizing the surface of NG and facilitating Li+ migration at the NG-electrolyte interface. The full cell with the c-Fe3O4-NG anode shows significantly improved charging behavior without loss of reversible capacity during 300 cycles. This study provides utilitarian insights for the development of advanced lithium-ion batteries for electric vehicle applications.

Summary: Si-based materials are highly promising candidates for high performance Li-ion batteries, and Si/graphite anode is commonly used to enable commercial applications. However, the poor interfacial bonding strength and limited ability to relieve volume expansion of silicon hinder the cycle performance. In this study, a novel Si-based anode structure with a double protective layer, combining inner graphite and outer TiC, is introduced to improve electrical conductivity, alleviate volume expansion, and suppress side reactions. The Si@G@TiC electrode demonstrates significantly improved cycling performance and retains 85% capacity after 300 cycles at 0.2 A g-1.

Summary: Due to high consumer demand, the widespread manufacturing of lithium-ion batteries (LIBs) leads to inevitable e-waste which poses severe environmental and resource sustainability challenges. This study enhances the charge storage capability and Li-ion kinetics of recovered graphite anode from spent LIBs by using an optimized amount of recycled graphene nanoflakes (GNFs) as an additive. The WG@GNF anode shows significantly improved electrochemical performance, with higher initial discharge capacity and better capacity retention over cycles compared to WG. The synergistic effects of Li-ion intercalation and adsorption into graphite and GNF respectively, along with the unique morphology of spherical graphite particles trapped in graphene nanoflakes, contribute to the enhanced performance.

Summary: This work investigates the formation of adjoining twin pairs (ATPs) at grain boundaries (GBs) in hexagonal close-packed (hcp) metals, focusing on the co-nucleation (CN) of pairs of deformation twins. A continuum defect mechanics model is proposed to study the energetic feasibility of CN of ATPs resulting from GB dislocation dissociation. The model reveals that CN is preferred over the nucleation of a single twin variant for low misorientation angle GBs. Further analysis considering GB character and twin system alignment suggests that CN events could be responsible for ATP formation even at low m' values.

Summary: This study investigates the behavior of electric-field induced antiferroelectric to ferroelectric (AFE-FE) phase transition and reveals the evolution of atomic displacement ordering as the cause for the transition behavior changing from sharp to diffuse. The novel semi-ordered configuration results from the competing interaction between long-range displacement modulation and compositional inhomogeneity, which leads to a diffuse AFE-FE transition while maintaining the switching field.

Summary: In this work, a physics-constrained neural network is used to predict grain-level responses in FCC material by incorporating crystal plasticity theory. The key feature, shear strain rate of slip system, is identified based on crystal plasticity and incorporated into the loss function as physical constitutive equations. The introduction of physics constraints accelerates the convergence of the neural network model and improves prediction accuracy, especially for small-scale datasets. Transfer learning is performed to capture complex in-plane deformation of crystals with any initial orientations, including cyclic loading and arbitrary non-monotonic loading.

Summary: This study attempts to address the gap in cooling rates between thin film deposition and bulk metallic glass (BMG) casting by correlating the glass-forming range (GFR) determined from combinatorial materials chips (CMCs) with the glass-forming ability (GFA) of BMG. The results show that the full-width at half maximum (FWHM) of the first sharp diffraction peak (FSDP) is a good indicator of BMG GFA, and strong positive correlations between FWHM and the critical casting diameter (Dmax) are observed in various BMG systems. Furthermore, the Pearson correlation coefficients suggest possible similarities in the GFA natures of certain BMG pairs.
