Inside nearly every battery you use is a collection of electrode particles arranged similarly to the stars that make up our galaxy.
For years, researchers have understood those particles, particularly in in lithium-ion batteries, to be fixed and remain relatively stable throughout a battery’s life.
Yet new research published in “Sciene” overturns that long held assumption, showing that many of these particles move more like shooting stars or meteors, adding a new dimension to our understanding of battery degradation, explained Juner Zhu, a Northeastern University professor of mechanical and industrial engineering and one of the authors of the research.
The findings could help lay the groundwork for longer-lasting and more reliable…
