Fluorine-intercalated graphite, C_xF with x=2.8, was tested for the cathode active material of an all-solid-fluoride-ion shuttle battery. The addition of copper fluoride facilitated the discharge reaction of C_xF. It was discharged up to 0.4 V vs. Pb and the resulting carbon was charged up to 1.6 V, regenerating C-F bonding. A highest capacity of 230 mAh g⁻¹ was delivered when 80 wt% (67 mol%) of CuF₂ was added and utilization of C_xF reached 98%.

氟离子穿梭电池正极的氟嵌入石墨的充放电行为

对于全固态氟化物离子穿梭电池的正极活性材料，测试了氟嵌入的石墨C _x F（x = 2.8）。氟化铜的添加促进了C _x F的放电反应。将其放电至相对于Pb高达0.4 V，所得到的碳充电至1.6 V，从而再生CF键。当添加80 wt％（67 mol％）的CuF ₂且C _x F的利用率达到98％时，最高容量为230 mAh g ^-1。
