← ScienceWhich outcome results when a desiccant reduces humidity inside lithium-ion pouch cell?
A)Hydrolysis reactions decrease, cell lifespan increases✓
B)Ionic conductivity decreases, power output drops
C)Electrolyte viscosity increases, charge rate diminishes
D)Surface passivation forms, capacity fades quicker
💡 Explanation
Reduced humidity minimizes water available to hydrolyze LiPF6 salt, decreasing HF formation by the hydrolysis mechanism; therefore, cell degradation slows and lifespan increases, rather than other electrochemical performance parameters being directly restricted by water.
