Conductivity of Li{sub x}Mg{sub y}Al{sub z}(SO{sub 4}){sub 3} as a new lithium ionic conductor for a solid-state cell
- NTT Interdisciplinary Research Labs., Ibaraki (Japan)
The conductivity of Li{sub x}Mg{sub y}Al{sub z}(SO{sub 4}){sub 3} system as a new lithium ionic conductor has been investigated. It is demonstrated that the addition of Al{sub 2}(SO{sub 4}){sub 3} substantially increases the conductivity of the Li{sub 2}SO{sub 4}-MgSO{sub 4} system. The highest conductivity and the lowest activation energy are observed for Li{sub 3.3}Mg{sub 0.6}Al{sub 0.5}(SO{sub 4}){sub 3}. The conductivity is 4 {times} 10{sup {minus}5} and 1 {times} 10{sup {minus}6}S/cm at 100 and 25 C, respectively. The activation energy is 0.49 eV in the 25 to 200 C temperature range. The electronic conductivity is 1.1 {times} 10{sup {minus}9} S/cm at 150 C, and the electronic transference number is 1 {times} 10{sup {minus}5}. Therefore, the Li{sub x}Mg{sub y}Al{sub z}(SO{sub 4}){sub 3} system is a lithium ionic conductor, and it is suitable as a solid electrolyte for a solid-state cell.
