Effect of interstitial Li + ion and vacant site Li + ion on the properties of novel Li 2.05 ZnAl 0.05 Si 0.95 O 4 and Li 1.95 Zn 0.95 Cr 0.05 SiO 4 ceramic electrolytes

Lisicon-typeceramic electrolytes, Li2.05ZnAl0.05Si0.95O4 (interstitial Li-ion) and Li1.95Zn0.95Cr0.05SiO4 (Li-ion vacant site) were synthesized by sol gel method. X-ray diffraction was applied to investigate the phase, structure and unit cell parameters of both solid electrolytes. Complex impedance...
