Summary: Metal phosphates have potential as anode materials for alkali-ion batteries due to their stability, low voltage, and high capacity. However, there is limited research on their application in potassium-ion batteries, and the potassium storage mechanism is not well understood. In this study, a chromium phosphate@N-doped carbon composite is synthesized and shown to be a promising conversion-type anode material for potassium-ion batteries. The composite exhibits good capacity, rate capability, and stability, and experimental evidence suggests a conversion reaction occurs during the potassiation process.

Summary: The study successfully synthesized a promising high-voltage spinel oxide cathode material MgCrMnO4 with 18% Mg/Mn inversion, and designed a new custom operando battery device to investigate cation migration mechanisms. The research showed both reversible and partially reversible Mg2+ insertion in the cathode, with inverted Mn believed to be involved in cation migrations causing irreversible structural evolution.

Summary: Using first-principles calculations, we investigate the energy characteristics of alkali metal (AM) atom intercalation into bulk tetracene crystals. We find that intercalation of AM atoms (Li, Na, K, Rb, Cs) into bulk tetracene crystals is energetically favorable, with lower intercalation energy than that for graphite. The intercalated crystals show high diffusivity and can exhibit semiconducting-metallic-semiconducting behavior as the AM atom concentration increases.

Summary: In this study, the crucial role of electrolyte in governing the kinetics of nucleation during phase transformations of metal-ion battery materials was demonstrated. By comparing nucleation rates in carbonate and aqueous electrolytes, it was found that the nucleation rate in aqueous electrolyte is one order of magnitude higher. This leads to a decrease in hysteresis of charge and discharge curves in an aqueous medium by 30%, significantly improving the energy efficiency of cells with an aqueous electrolyte. Detailed characterization of lithium-ion intercalation kinetics was provided, and assumptions about the possible reasons for the solvent dependence of nucleation kinetics were formulated.

Summary: We conducted a comparative study of the conductivity data of weak and strong electrolytes and discovered previously unknown differences and similarities. By considering the neutralization of excess protons and proton holes in water, we developed a model that explains the conductivity of aqueous solutions. Our results suggest that the aggregation of species in weak electrolytes may be the main factor causing the difference in conductivity between weak and strong electrolytes. These findings advance our understanding of the dynamic structure of aqueous electrolyte solutions and have important implications for nanofluidic, biological, and electrochemical systems.

Summary: The electrodynamics properties of nanoconfined water have been significantly changed compared to bulk water, providing opportunities for safe electrochemical systems. We present a nanofluidic water-only battery that exploits the unusually high electrolytic properties of pure water under strict confinement. The device, composed of carbon-based nanomaterials, creates interconnected nanochannels filled with water between the separator and electrodes. The efficiency of the battery shows a maximum energy density at 3 nm, challenging the current metal-ion batteries. Our findings establish the electrodynamic fundamentals of nanoconfined water and pave the way for low-cost and inherently safe energy storage solutions needed in the renewable energy sector.
