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.

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.
