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.
作为 ICD 锂电池的潜在阴极材料，Ag(6)Mo(2)O(7)F(3)Cl（SMOFC）的一个优点是其在 3V（相对于 Li(+)/Li）以上具有约 133mAh/g 的增强重量容量，这是由 3.46V 和 3.39V（相对于 Li(+)/Li）处的两个双相转变产生的。SMOFC 的独特晶体结构能够实现高银离子传导：sigma( perpendicular[001]) = 3.10(-2) S/cm（+/-2.10(-2) S/cm）和 sigma(//[001]) = 4.10(-3) S/cm（+/-2.10(-3) S/cm），因此具有出色的放电率能力。通过原位 XRD 测量和 HRTEM 研究监测了锂离子的嵌入。在四个插入的锂离子之后，结构呈线性各向同性坍塌，导致完全非晶结构。
