Status and development trends for fluorinated carbon in China

Fluorinated saccharide-derived hard carbon as a cathode material of lithium primary batteries: effect of the polymerization degree of the starting saccharide

“…The binding energy of the C–F, –CF 2 , and –CF 3 groups in the C 1s spectrum experiences a blue shift with an increase in the F/C ratio. 43 This change can also be seen in the F 1s spectra of FHCs, as shown in Fig. S7b †.…”
