“…Figure c shows that a relatively obvious reduction peak of CF x appears at about 2.1 V and disappears in the subsequent CV curve (Figure d,e), indicating that it is difficult to recycle CF x after reduction. Refs and report studies on CF x materials obtained from fluorinated biomass-derived carbon materials and porous carbon materials. The discharge platform of CF x materials obtained from fluorinated biomass-derived carbon materials and porous carbon materials is between 2.5 and 1.7 V, which is consistent with our data.…”

Transition metal fluorides are potentially high specific energy cathode materials of next-generation lithium batteries, and strategies to address their low conductivity typically involve a large amount of carbon coating, which reduces the specific energy of the electrode. In this study, Mn y Fe1–y F3@CF x was generated by the all-fluoride strategy, converting most of the carbon in Mn y Fe1–y F3@C into electrochemical active CF x through a controllable NF3 gas phase fluorination method, while still retaining a tightly bound graphite layer to provide initial conductivity, which greatly improved the energy density of the composite. This synergistic effect of nonfluorinated residual carbon (∼11%) and Mn doping ensures the electrochemical kinetics of the composite. The loading mass of the active substance had been increased to 86%. The theoretical and actual discharge capacity of Mn y Fe1–y F3@CF x composite was up to 765 mAh g–1 (pure FeF3 is 712 mAh g–1) and 728 mAh g–1, respectively. The discharge capacity at the high-voltage (3.0 V) platform was more than three times higher than that of the non-Mn-doped composite (FeF3@CF x ).

“…Since the commercialisation of the first Li/CF x battery in the 1970s, remarkable progress has been made in the materials and reaction mechanisms of this battery technology. Numerous CF x materials, such as fluorinated graphene (FG), 11,12 fluorinated nanotubes, 13,14 fluorinated carbon fibers, 15,16 fluorinated nanoparticles, 17 fluorinated fullerene (C 60 ), 18 fluorinated hard carbon, 19 and fluorinated biomass-derived carbon, 20 have been used to fabricate Li/CF x batteries (Fig. 1).…”
