Summary: In this study, we propose a selective solvation approach combining glyme and hydrofluoroether solvents. The selective solvation of Mg2+ by the glyme solvent component increases the oxidative stability of glyme while maintaining sufficient reductive stability of the non-coordinating hydrofluoroether. This approach enables the design of electrolytes with greater oxidative stability than glyme-only electrolytes while retaining enough reductive stability to cycle Mg metal. We also investigate the influence of various coordination interactions among the solvents and anions with Mg2+ on their electrochemical stabilities to better inform the design of future electrolytes.

Summary: Practical Mg batteries require electrolytes with stability towards both reduction by Mg metal and oxidation by high voltage cathodes. State-of-the-art Mg electrolytes based on weakly coordinating Mg salts use ether-type solvents for reductive stability, but their oxidative stabilities are not ideal. In this work, a selective solvation approach using a combination of glyme and hydrofluoroether solvents is reported to improve the oxidative stability while maintaining the reductive stability necessary for Mg cycling. The study also relates the coordination interactions among solvents and anions with Mg2+ to inform the design of future electrolytes.

Summary: The carbon byproduct from methane pyrolysis in molten salts can be used as an anode or conductive additive for secondary Li-ion and Na-ion batteries. The use of catalytic molten salt mixtures results in more graphitic carbon co-products, which exhibit the best electrochemical performance as Li-ion anodes. However, the presence of retained salt species in the carbon structure leads to reduced electrochemical activity and reversibility.

Summary: This study reports a hydrogen-bond disrupting electrolyte strategy to enhance the stability of proton batteries by modifying the ion solvation sheath and electrode interface. Mixing cryoprotectants with acids disrupts hydrogen bonds involving water molecules, resulting in reduced water activity and modified ion solvation sheaths. Additionally, the cryoprotectants protect the electrode surface from water. Experiment results demonstrate fast and stable proton storage even at low temperatures.

Summary: In the development of aqueous organic redox flow batteries (AORFBs), anthraquinone derivatives (AQs) attract a great deal of attention as promising negative electrolytes. This study presents a solvation regulation strategy to extend the lifetime of 2,6-dihydroxyanthraquinone (DHAQ) electrolytes by incorporating tetramethylammonium cations (TMA(+)) to interfere with the solvation structure of DHAQ(2-)/DHAHQ(4-) anions. The strategy effectively reduces the capacity fade rate of DHAQ/K4Fe(CN)(6) cells caused by electrolyte decomposition.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
