← ScienceWhich process limits charge carrier mobility in solid electrolytes?
A)Ionic hopping between lattice defects✓
B)Electronic band structure formation
C)Phonon scattering becomes negligible
D)Space charge layer destabilization
💡 Explanation
Ionic conductivity depends on ion movement; the mechanism is ionic hopping. Temperature and defects facilitate hopping; ionic movement is limited by lattice defects because ions must have nearby vacancies to hop, therefore lattice imperfections limit movement, rather than other options for electrical conductivity.
