Scanning electron microscopy
Imaging a surface with a focused electron beam at magnifications far beyond light microscopy. In battery work it shows particle cracking, plated lithium and coating morphology; cross-sections show the layer structure of an electrode.
- Abbreviation
- SEM
Example
Materials analysis and post-mortem: an example situation
Surface and bulk measurements may find different compositions in the same electrode without contradiction.
Read Scanning electron microscopy alongside Particle cracking in this context. Fracture of active-material particles from the volume change of repeated lithium insertion and removal. New surfaces consume electrolyte to form fresh SEI, and fragments that lose contact no longer store lithium.
Use in Lemonergy
Connect results with scale and specimen preparation.
This is a reference concept. No executable Lemonergy block has been verified for this term.
