← ScienceWhich mechanism causes decreased reaction rate in solid-state electrolyte batteries at low temperatures?
A)Ionic conductivity decrease via Arrhenius relation✓
B)Electrode surface passivation from oxidation
C)Active material decomposition via disproportionation
D)Interfacial delamination due to thermal contraction
💡 Explanation
When temperature drops in solid-state batteries, the ionic conductivity decreases because ion transport becomes exponentially slower based on the Arrhenius relation, sharply reducing reaction rate. Therefore decreased ionic conductivity reduces rate, rather than passivation, decomposition, or delamination that require different triggering events or conditions.
