← ScienceWhich outcome occurs when a voltage above oxidation potential is applied to a lithium-ion battery's electrolyte?
A)Electrolyte decomposition, gas evolution starts✓
B)Uniform lithium plating on anode ends
C)Cathode de-intercalation rate accelerates smoothly
D)Dendrite formation uniformly slows down
💡 Explanation
Electrolyte decomposition and gas evolution commence above the threshold. This is due to oxidation, specifically oxidative decomposition; because the electrolyte's stability is surpassed due to applied over-potential; therefore, gas formation follows rather than uniform lithium deposition.
