Ionic conductivity
How readily an electrolyte carries ions, in siemens per centimetre. Liquid carbonate electrolytes reach about 10 mS/cm at room temperature; the best sulfide solid electrolytes match that, while polymers fall far short unless heated. [1]
- Abbreviation
- σ
- Unit
- mS/cm
Example
Electrochemistry fundamentals: an example situation
A circuit can predict terminal voltage while leaving electrode potentials and reaction kinetics unresolved.
Read Ionic conductivity alongside Electrolyte in this context. The ion-conducting medium between the electrodes. In a liquid-electrolyte cell it fills the pores of both electrodes and the separator, so it is not a separate structural layer.
Use in Lemonergy
Connect reaction sites and transport paths.
This is a reference concept. No executable Lemonergy block has been verified for this term.
