Summary: In this study, a series of battery tests and spectroscopic studies were conducted to understand the chemical stability of K-4[Fe(CN)(6)] and its charged state, K-3[Fe(CN)(6)]. It was found that in a strong alkaline solution (pH 14), the K-4[Fe(CN)(6)]/K-3[Fe(CN)(6)] half-cell experiences fast capacity decay under dark conditions. The studies also revealed a slow CN-/OH- exchange reaction of K-3[Fe(CN)(6)] at pH 14, leading to the irreversible decomposition of K-4/K-3[Fe(CN)(6)].

Summary: This paper reviews organic molecules used as the redox-active electrolyte for the positive cell reaction in aqueous redox flow batteries. The key metrics to assess their performance are discussed, and a new figure of merit called the theoretical intrinsic power density is introduced. The theoretical intrinsic power densities of organic electrolytes are much higher than that of the VO2+/VO2+ couple, with TEMPO-derivatives showing the highest performance.

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: With the development of consumer electronic devices and electric vehicles, lithium-ion batteries are crucial for high energy storage. However, they still cannot meet the demands of rapidly growing industries. Metal batteries, with higher energy density, are considered as the next-generation devices. Challenges such as uncontrolled dendrite growth and high reactivity hinder the commercialization of metal batteries. This review discusses the failure mechanism of lithium/sodium metal anodes and explores potential solutions through electrolyte optimization, solid-electrolyte interphase layer formation, and nanoengineering at the material level.

Summary: In this study, the mechanism of Ni-catalyzed electrochemical aryl amination reactions was investigated through experiments and calculations. The results revealed that the coordination of an amine to the Ni-II catalyst, followed by the generation of a stable Ni-II aryl amido intermediate and reductive elimination, were key steps in the reaction. The findings provide new insights into the mechanism of this reaction and offer guidance for the development of other Ni-catalyzed electrosynthetic reactions.
