Charge-discharge behavior of fluorine-intercalated graphite for the positive electrode of fluoride ion shuttle battery

Charge-discharge behavior of fluorine-intercalated graphite for the positive electrode of fluoride ion shuttle battery

Fluorine-intercalated graphite, CxF 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 CxF. It was discharged up to 0.4 V vs. Pb and the resulting carbon was charged up to 1.6 V,...
