Applied stress can control lithium intrusions in solid electrolytes

The performance of solid electrolytes is hindered by instabilities caused by the formation of lithium intrusions. The mechanism responsible for these intrusions is not well understood. Experiments with a scanning electron microscopy setup revealed that applied stresses can control the probability of intrusion formation and influence the propagation behaviour.
