Summary: In this study, high-entropy oxide (HEO) nanofibers were used as sulfur hosts for the first time, showing good rate capacity and cycling stability due to strong chemical interaction with lithium polysulfides. The tap density of the sulfur/HEO composite was also significantly higher than that of the sulfur/CNT composite, leading to a higher volumetric capacity. This research provides a promising strategy for improving the volumetric energy density and electrochemical performance of lithium-sulfur batteries.

Summary: The study compares the correlation between mechanical strength and cycle performance of cathode materials, particularly those with layered structures. By improving the particle hardness of cathode materials through Mg doping, undesirable microcracks within the particles during cycling can be effectively suppressed, leading to improved cycle performance. Structural and electrochemical analyses are conducted to further understand the mechanical degradation mechanism of LIBs during repeat cycles and explore ways to enhance electrochemical performance and long-term durability in current cathode materials.

Summary: Lithium-sulfur batteries have attracted attention as a promising energy storage system due to their high energy density, low cost, and environmental friendliness. However, challenges such as capacity decay and poor cycling stability arise from the dissolution of lithium polysulfides during cycling. Catalysts have shown significant progress in addressing these issues by promoting redox reactions and suppressing the shuttle effect. The concept of medium and high entropy materials has emerged as a novel approach for designing advanced catalysts for lithium-sulfur batteries.

Summary: Due to the excellent discharge capacity provided by oxygen redox activity, Li-rich layered oxide positive electrode materials have attracted great attention. However, there is still no consensus regarding the role of ionocovalency of transition metal-oxygen chemical bonding in the reversibility of oxygen redox and the local crystal and electronic structure transformations. In this study, we successfully manipulated the cationic/anionic redox contributions to the overall electrochemical activity and investigated the importance of enhancing the covalency of the TM-O bonding for anchoring the reversibility of the charge compensation mechanism.

Summary: Li metal anodes have been widely studied for their high capacity, but the growth of Li dendrites and poor cycle life limit their practical application. Anode-free batteries (AFBs) without Li metal have advantages in energy density, cost-effectiveness, and cell fabrication. However, AFBs suffer from continuous capacity fading. In this study, Li2Cu0.6Ni0.4O2 (LCNO) is introduced as a sacrificial cathode additive to improve the cyclability of AFBs.

Summary: Ni-rich and low-Co NCM/NCA materials with high energy density are driving the development of electric vehicles, but their poor electrochemical cycling performance and safety issues need to be addressed before commercialization. Understanding the internal mechanisms of these materials, such as lattice distortion, lithium-nickel mixing, microcracking, and oxygen generation, can help accelerate their large-scale application and dominance in electric vehicles through targeted component and structure design and interface modification methods.

Summary: A critical decay time (CDT) model is introduced to predict the critical energy for direct detonation initiation in gaseous mixtures. The model is based on a global initiation criterion that ensures the decaying shock speed remains within a specific range below the Chapman-Jouguet (CJ) speed for a critical decay time. The CDT model provides accurate estimations of critical initiation energy for various fuel-oxidizer mixtures.

Summary: In this work, ultra-thin titanium trisulfide (TiS3) nanosheets were synthesized using space-confined vapor method, and a TiS3-TiOx-TiS3 in-plane heterojunction was fabricated for memristor applications using laser manufacturing. The memristor device showed reliable analog switching behaviors due to flux-controlled migration and aggregation of oxygen vacancies, allowing incremental adjustment of channel conductance by tuning the programming voltage. The device exhibited excellent linearity and symmetry in conductance change during long-term potentiation/depression processes, and achieved a high accuracy of 90% in pattern recognition task when integrated into a neural network. The results demonstrate the great potential of TiS3-based synaptic devices for neuromorphic applications.

Summary: This work studies the initial-boundary value problem for a class of finite degenerate fourth-order parabolic equations with mean curvature nonlinearity. By using the Nehari flow and Levine's concavity method, the size of the initial data set is described under sub-critical, critical, and supercritical initial energy levels. It is shown that the solution exists globally and decays for initial data starting from one region of phase space, while blow-up phenomena occur in finite time for initial data corresponding to another region.
