Summary: P2-type Fe/Mn-based layered oxide cathode has attracted significant attention for its low cost, low toxicity, earth abundance, and high theoretical capacity in sodium-ion battery applications. However, the harmful P2-P2' phase transition associated with the Jahn-Teller effect of Mn3+ during the discharge process limits its cycling stability. In this study, Al-doping is proposed as an effective strategy to suppress the phase transition and improve the cycling stability and rate capability of the electrode.

Summary: The study demonstrates the anion redox chemistry in O3-type layered oxide cathode materials and proposes a strategy involving ZrO2 coating and Zr4+ doping to enhance the activity, reversibility, and stability of oxygen redox reactions. The integration of Zr4+ doping optimizes lattice structure, reduces diffusion resistance, and increases structural stability, while ZrO2 coating effectively mitigates electrolyte corrosion and inhibits the formation of Na2CO3, indicating potential for regulating oxygen redox activity in cathode materials.

Summary: In this study, a new Li-doped P2-Na0.8Li0.15-Cu0.1Mn0.75O2 cathode material was designed, and the electrochemical performances of both materials were systematically investigated. The doped sample showed higher reversible capacity, better rate capability, and stronger cycling stability compared to the undoped sample. These improvements are believed to result from the positive effect of Li on triggering anionic redox and facilitating ion and electron diffusion during the sodiation/desodiation process.

Summary: A feasible interfacial modification strategy using Mn3O4 surface coating is proposed to construct a protective layer and alleviate Jahn-Teller distortion during the charge/discharge process. The increase of oxygen vacancy on the surface of LRNMO after Mn3O4 modification effectively restrains the release of oxygen and improves rate capability, thereby enhancing its electrochemical performances.

Summary: Anionic redox can boost the energy density of metal-oxide cathodes, but TMO6 subunits are inherently rigid and may not tolerate inner strains induced by lattice glide. A designed material with vacancies in TM sites and Mg ions improves flexibility and stability, maintaining a long voltage plateau at 4.2 V during deep desodiation. The strategy paves the way for highly stable cathode materials with reversible anionic redox for sodium-ion batteries.

Summary: This paper establishes a tripartite evolutionary game model involving the government, port enterprise, and port residents to explore the key variables affecting the implementation of emission reduction measures by the port enterprise. The study finds that in the initial stage, the government's incentive policies and port residents' supervision are the driving forces behind the port enterprises' implementation of emission reduction measures. As emission reduction technology advances, the cost of port enterprises will decrease, and the incremental income after emission reduction will gradually compensate for part of the input cost.

Summary: In this study, we investigate the eigenvalue problem for a system of coupled integral operators and analyze the existence, monotonicity, and asymptotic behavior of the principal eigenvalue and eigenpair. As applications, we examine stem cell regeneration models with epigenetic transitions and gene mutations. These models lead to three classes of nonlinear integro-differential evolution equations. We explore the existence, uniqueness, and multiplicity of positive steady states as well as the long-term behavior of time-dependent solutions and obtain explicit formulae for threshold values related to tissue development, degeneration, and abnormal growth.

Summary: In this article, we study a general class of cooperative systems with nonlocal diffusion operators. These systems can be either strong in cooperation or strong in the coupling of the nonlocal diffusion operators. We prove various results regarding the properties of these systems, including existence, uniqueness, multiplicity, variational characterizations, spectral bounds, essential spectrum, and the relationship between the sign of principal eigenvalue and the validity of the maximum principle. Our approach is elementary and does not rely on the Krein-Rutman theorem.

Summary: Prelithiation is an essential technology to compensate for initial lithium loss in lithium-ion batteries, but its practical application is hindered by reactive prelithiated materials. This study proposes interphase engineering to protect prelithiated electrodes, using carefully selected solutions to construct artificial solid electrolyte interphase (SEI) films. The electrochemical evaluation shows that the fluorinated artificial SEI not only enhances interfacial ion transport but also increases the tolerance of the prelithiated electrode to air, enabling high capacity and negligible capacity decay.

Summary: The development of all-solid-state lithium batteries is an important direction for next-generation lithium-ion batteries, which are characterized by high energy density, long cycle life, low cost and high safety. However, there are some challenges in the application of lithium-rich cathode materials in all-solid-state lithium batteries, such as poor electronic conductivity, irreversible redox reaction, and structure transformation. Recent research progress in various solid-state electrolyte systems provides opportunities for the application of lithium-rich cathode materials, but further studies on cathode material composition regulation, lithium ion and electron transport pathways, and interface modification are needed to solve the existing issues.

Summary: Polymeric conducting binders have significant research value as they can serve as both binders and conducting agents, increasing the proportion of active materials in batteries and the volumetric energy density. This study explores the potential of a composite of PEDOT:PSS and polyethylene glycol (PEG) as a high-performing binder for silicon anodes. The addition of PEG polymer enhances the conductivity of PEDOT:PSS and improves the mechanical properties of the silicon anode, resulting in extended cycle endurance. The use of operando optical microscopy allows for direct observation of the binder's operation. Consequently, the bifunctional PEDOT:PSS/PEG binder shows promise for high-performance lithium-ion battery binders.

Summary: Metal fluorides as conversion-reaction cathodes have advantages such as low cost, environmentally friendly, and high energy density. In this study, a hydroxyl-rich copper fluoride (Cu2(OH)3F) was proposed as a conversion cathode, coupled with an electrolyte additive engineering, to address the poor reversibility issue. The presence of OH in Cu2(OH)3F enables effective suppression of Cu+ dissolution, resulting in better reaction reversibility and kinetics.
