Summary: High-voltage lithium-ion batteries using high-voltage electrolytes can improve energy density and power density, but face challenges such as electrolyte decomposition and unclear interfacial side reactions. A new additive-free electrolyte has been developed to address these issues, providing stability at high voltage, lithium-dendrite-free features during fast charging, and superior performance at low temperatures. Additionally, a new solvation structure-related interfacial model has been introduced to help interpret battery performance and guide the design of versatile electrolytes for metal-ion batteries.

Summary: This study proposes a carbonization method to construct microsized-silicon as an anode for lithium-ion batteries. The carbonized organic binder serves as both a carbon resource and a physical framework, ensuring stable electric channel and the formation of a stable solid-electrolyte interphase. The carbon binder also acts as a physical buffer and modifies surface reactivity, enabling high initial Coulombic efficiency and stable cycle performance.

Summary: An extraction system composed of 0.4 mol/L 2-thenoyltrifluoroacetone (HTTA), 0.4 mol/L trioctylphosphine oxide (TOPO), and ionic liquid (IL) 1-Butyl-3-MethylImidazolium bis (trifluoromethyl sulfonyl) imide was designed to recover valuable metals from spent Li-ion batteries (LIBs). The optimized conditions achieved high extraction efficiencies for Co, Mn, and Ni while only coextracting a small percentage of Li. UV spectrum analysis confirmed the involvement of CH3COO- in the extraction reaction.

Summary: Sodium-ion batteries (SIBs), a promising alternative to lithium-ion batteries (LIBs), are essential for future electric vehicles and energy storage systems. While the recycling of spent SIBs and LIBs face similar environmental and economic challenges, the recycling of SIBs is more economically demanding. Proactive strategies must be implemented during the early commercialization stage to ensure easy recycling, low operation costs, and optimal efficiency of SIBs. This Perspective article provides an overview of the components of SIBs, discusses recycling strategies, and highlights the challenges and future prospects of SIB recycling.

Summary: The experimental results show that the mu(Li) in two-phase electrode materials immediately changes after loading and then gradually changes while maintaining a constant mechanical load. Loading and unloading lead to mu(Li) variations in the opposite direction. This characteristic mu(Li) variations can be explained by considering the change in the phase equilibrium between the two phases.

Summary: Data-driven material exploration is an important research method, but recording, analyzing, and sharing daily experimental results can be difficult. We have developed a data platform that accurately describes the relationships between structures, properties, and processes, and applied it to explore organic superionic glassy conductors through over 500 experiments. Automated data analysis has revealed the key factors for achieving remarkable room temperature ionic conductivity and Li+ transference number. Unlike previous research, all experimental results, including graphs, raw measurement data, and data processing systems, are accessible to everyone in a public repository. This direct data sharing will enhance scientific communication and accelerate the integration of material knowledge.
