Microscopic bumps misled researchers tracking ion movement in batteries

KAIST researchers discovered that a signal long believed to show ion movement inside batteries is often just an optical illusion caused by rough surfaces.

KAIST pinpoints artifacts behind unreliable battery nanoscale analysis

A signal that seems to reveal lithium ions racing through a battery may, in fact, be nothing more than a topographical illusion. Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have traced one of the most stubborn sources of error in nanoscale battery analysis to a surprisingly mundane cause: uneven surfaces. In […]
