AbstractThe use of aqueous/non-aqueous biphasic electrolyte solutions in Li-based battery systems circumvents the limitations of poor reductive stability of aqueous electrolyte solutions, broadening their electrochemical stability window. However, aqueous/non-aqueous electrolytes suffer from biphasic mixing and high impedance when Li ions cross the biphasic interface.

AbstractHydrogen oxidation reaction in alkaline media is critical for alkaline fuel cells and electrochemical ammonia compressors. The slow hydrogen oxidation reaction in alkaline electrolytes requires large amounts of scarce and expensive platinum catalysts. While transition metal decoration can enhance Pt catalysts’ activity, it often reduces the electrochemical active surface area, limiting the improvement in Pt mass activity.

Correction to: Nature Communications https://doi.org/10.1038/s41467-024-45374-0, published online 08 February 2024In this article, the y-axis labels for Fig. 8b, d and Supplementary Figs. 30, 31, and 32b were wrongly labeled as “Potential (V vs Li/Li+)” but should have been “Cell voltage (V)”; the figures should have appeared as shown below. Besides, the caption for Fig.

AbstractMicro-sized silicon anodes can significantly increase the energy density of lithium-ion batteries with low cost. However, the large silicon volume changes during cycling cause cracks for both organic-inorganic interphases and silicon particles. The liquid electrolytes further penetrate the cracked silicon particles and reform the interphases, resulting in huge electrode swelling and quick capacity decay.
