Abstract

As a potential cathode material for the ICD lithium battery, one advantage of Ag 6Mo 2O 7F 3Cl (SMOFC) Is its enhanced gravimetric capacity of ca. 133 mAh/g above 3 V (vs Li +/Li) delivered by two biphasic transitions at 3.46 and 3.39 V (vs Li +/Li). The unique crystal structure of SMOFC enables a high sliver ion conduction: σ [001] = 3.10 -2 S/cm (±2.10 -2 S/cm) and σ// [001] = 4.10 -3 S/cm (±2.10 -3 S/cm) and, hence, an excellent discharge rate capability. Lithium insertion has been monitored by in situ XRD measurements with HRTEM investigations. There is a linear isotropic collapse of the structure leading to a fully amorphous structure beyond four Inserted lithiums.
