a XRD patterns of ME-PBSCC with the Rietveld refinement results. b HR-TEM images of the ME-PBSCC and a line scanning result along the red frame. c HAADF and elemental mapping images of the ME-PBSCC at a scale bar of 200 nm. d EDX spectrum and atomic percentage derived from the particle in (c). e The O 1s spectra and f the electrical conductivities of ME-PBSCC and PBS32C samples. Each test was conducted in triplicate to obtain statistical standard deviations, presented as error bars.
