Abstract

Solid state lithium-ion battery represents an important trend of battery technology. For the researching for the interface's performance of solid state electrolyte, in this work, LLZO with different dopants (Ta, Nb, Sb and Te) was synthesized and the conductivity and interfacial resistance with lithium metal were compared. The ionic conductivity and interfacial properties under different temperatures were also investigated. The results show that the LLZO doped with Ta maintained the ionic conductivity of 5×10^-4 S/cm and had the best performance in terms of the interfacial resistance. The EIS results showed that the interfacial resistance was decreasing with the increasing temperature, so that the LLZO would be one of the most promising solid state electrolyte.
