Summary: Through the investigation with in situ Raman spectroscopy, XANES spectroscopy, and HRTEM, it was found that the voltage-fading mechanism of Li-rich materials is nearly reversible in the whole charge-discharge cycle but becomes irreversible upon long-term cycling, leading to structural collapse and undesirable voltage fading. This finding is significant for a better understanding of the redox reaction mechanisms of high-capacity Li-rich cathodes.

Summary: Considering use cases and selecting the right features are crucial in developing battery lifetime prediction models. Prediction of cell-to-cell variability between identically cycled cells requires features that are not reliant on cycling conditions. While features encoding cycling conditions can boost model accuracy, they may lead to reduced transferability on identically cycled cells.

Summary: Rechargeable magnesium batteries (RMBs) are a promising energy-storage technology, but the development of high-performance cathode materials is a major challenge. This study demonstrates the high performance of ammonium tetrathiomolybdate as an RMB cathode material, which forms an amorphous structure with efficient magnesium-storage active sites and open transport pathways through ammonium extraction. The covalent-like molybdenum-sulfur bond weakens the interaction with magnesium ions and promotes simultaneous redox of molybdenum and sulfur, leading to high capacity.

Summary: By introducing a low coordinating number solvent (FEMC) into TFEP-based electrolyte, a high-stable anion-induced ion-solvent-coordinated (AI-ISC) structure based on coordination-number (CN) rule is successfully constructed to form a nonflammable CN-rule electrolyte (CNRE), which effectively suppresses undesired reactivity of the solvent molecules toward the graphite anode and Li anode. The 5Ah graphite||LiNi0.8Mn0.1Co0.1O2 pouch cell with this nonflammable CNRE exhibits favorable electrochemical performance and greatly improved safety compared to the cell with commercial LiPF6-EC/EMC electrolyte. Additionally, the pouch cell with the CNRE enables all-climate operation from -40 to +60 degrees Celsius, even retaining around 80% of its room-temperature capacity at -40 degrees Celsius. Furthermore, the commendable compatibility of this nonflammable electrolyte with Li-metal anode may pave the way for its extended application in Li-metal batteries.

Summary: Aqueous zinc-ion batteries (AZIBs) have excellent safety, low cost, and environmental friendliness, making them promising for large-scale energy storage systems. Layered oxovanadium phosphate dihydrate (VOPO4•2H2O) shows desirable properties as a cathode for AZIBs, but suffers from low operation voltage and unstable cycling. In this study, we introduce δ-oxovanadium phosphate (δ-VOPO4) as a new cathode material for AZIBs without the need for pre-embedding of metal elements or organics. The δ-VOPO4 exhibits superior performance with a discharge voltage of 1.46 V, a specific capacity of 122.6 mA h g(-1) at 1C, and an impressive capacity retention of 90.88 mA h g(-1) after 1000 cycles under 10C. These findings provide insights into the structure-function relationship in vanadyl phosphates and offer new opportunities for the development of high-performance AZIBs.

Summary: In recent years, aqueous Zn-ion batteries (ZIBs) have gained increasing attention as promising electrochemical energy storage systems for grid-scale applications due to their low cost, safety, and environmental friendliness. However, challenges in zinc metal anode, such as zinc dendrites growth and corrosion, hinder the development of ZIBs. To overcome these challenges, zinc-storage anodes have been extensively studied, with two-dimensional metal dichalcogenides (TMDs) like TiX2 (X = S, Se) showing great potential due to their unique properties. In this study, density functional theory (DFT) calculations are used to investigate the behavior of zinc intercalation reaction in TiX2, providing new insights for the design of high-performance battery materials.

Summary: Fluorine gas, with its unique properties, plays a crucial role in the development of lithium-ion batteries and sodium-ion batteries, particularly in cathode materials, electrolytes, and interfaces. The highly electronegative nature of fluorine enhances the ionic character and working potential in cathode materials, while fluorinated electrolytes possess good antioxidant and flame retardant properties. The fluorine-rich inorganic component is essential for the formation of a stable solid electrolyte interface on the electrode-electrolyte interface. However, there is still a lack of comprehensive understanding of the specific functions of fluorides in these batteries.
