← ScienceWhich outcome occurs when thermal runaway accelerates in lithium-ion battery packs?
A)Dendrite formation causes internal shorting
B)Heat generation accelerates electrolyte decomposition✓
C)Solid Electrolyte Interphase layer stabilizes
D)Current density limits diffusion polarization
💡 Explanation
Accelerating heat raises the reaction rate; therefore heat generation accelerates electrolyte decomposition via Arrhenius kinetics, because it reduces the activation energy. Decomposition increases gasses faster, rather than SEI stabilization, which would slow the rate.
