Considering the compositional complexity concept, novel solid electrolytes based on quaternary and quinary lithium superionic conductor (LISICON) systems were investigated for the development of highly ion-conducting materials. Phase identification indicated that even in highly complex compositions, relatively large Ti- and Ga-doping contents were difficult to achieve in the γ-Li3PO4framework. Relatively low ionic conductivities (10–7to 10–5S cm–1) and high activation energies (0.44–0.53 eV) were confirmed compared to ternary LISICON systems, indicating a negligible positive effect of the compositional complexity. In addition, undesirable anti-site disorder occurred in the LISICON crystal, which was considered to limit fast ion conduction in the quaternary and quinary LISICON systems. A further systematic and detailed study is therefore required to accurately determine the effects of compositional complexity in the design of fast ion conductors. |
