Ag(6)Mo(2)O(7)F(3)Cl: a new silver cathode material for enhanced ICD primary lithium batteries.
As a potential cathode material for the ICD lithium battery, one advantage of Ag(6)Mo(2)O(7)F(3)Cl (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 silver ion conduction: sigma( perpendicular[001]) = 3.10(-2) S/cm (+/-2.10(-2) S/cm) and sigma(//[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.
