The research team suggests their findings offer a valuable guide for selecting other alloy phases for anode materials in garnet-based solid-state batteries.
“Alloys with low eutectic temperatures and high mutual solubility with lithium should be prioritized in future research efforts,” concluded the team.
“By solving the interface stability issue while enhancing lithium diffusion kinetics, the LixAg alloy anode brings us one step closer to a future where solid-state batteries power everything from smartphones to electric vehicles with unprecedented energy density and safety.”
