In order to confirm the absence of cation migration across the interfacial region,
an EDS microanalysis has been carried out on the interface between anode and
electrolyte. We can see from the figures as following, there is no migration of Ba2+ or
Ni2+ ion.
Fig SI1. An EDS microanalysis on the interface between anode and electrolyte.
A comparison of the electrochemical performances of the synthesized materials
in this work with others reported in literatures have been presented, which are shown
as follows. We can seen from the Table SI1 that the single cell based on SDC-BSC
composite electrolyte has an excellent electrochemical performances, especially at
low operating temperature.
