Which risk increases when solid electrolytes containing lithium cations undergo high current density?

A)Lithium dendrite formation
B)Electrolyte thermal runaway
C)Increased interfacial resistance
D)Superionic conductivity reduction

💡 Explanation

Lithium dendrite formation increases because electromigration of lithium ions leads to uneven deposition, facilitating dendrite growth via the *space charge layer buildup* mechanism; therefore, lithium dendrites appear rather than uniform plating owing to inherent interfacial instabilities.
