Polymorphism and Li coordination in LiFeO2 ionic conductors
Despite the importance of the LiFeO2 phases as cathode materials in lithium ion batteries, little is known about their crystal structures. In the frame of our research project... -
Enhanced oxygen hyperstoichiometry in Y doped La9.33+xGe6O26+3x/2
Apatite-type lanthanide silicates/germanates have been attracting considerable interest as a new class of oxide ion conductors. The presence of interstitial oxide ions is... -
H+/Li+ exchange and Al/In substitutions in garnet-type Li ion conductors
In this work, we will examine the dopant site location, and Li distribution in cubic and In/Al doped La3Zr2Li7O12, which have been shown to display high Li ion conductivities... -
Local structure studies of mellilite oxide ion conductors
The development of new interstitial oxide conductors with less restrictive structural constraintsrequires understanding of the mechanisms allowing both incorporation and...
