Abstract

Polytetrafluoroethylene (PTFE), composed of fluorine and carbon atoms, has a potential to produce carbon-coated fluorides in the calcination of inorganic compounds. We synthesized high voltage cathode material for Na ion secondary battery, Na₂FePO₄F, using PTFE as the carbon-coating and fluorine source. The Na₂FePO₄F carbon-coated by a thermal decomposition of PTFE showed high discharge capacity (64.4 mAh g¹¹) at the first cycle of galvanostatic cycling by the improvement of conductivity.
