Swelling of the electrode-electrolyte interphase limits lithium battery performance, according to a new Science study. The findings could inform interface design in next-generation battery systems. ScienceResearch
Understanding the changes in interfaces between electrode and electrolyte during battery cycling, including the formation of the solid-electrolyte interphase , is key to the development of longer lasting batteries. Z. Zhang. adapt a thin-film vitrification method to ensure the preservation of liquid electrolyte so that the samples taken for analysis using microscopy and spectroscopy better reflect the state of the battery during operation.
—MSLAlthough liquid-solid interfaces are foundational in broad areas of science, characterizing this delicate interface remains inherently difficult because of shortcomings in existing tools to access liquid and solid phases simultaneously at the nanoscale. This leads to substantial gaps in our understanding of the structure and chemistry of key interfaces in battery systems.
