Abstract

FeF2/carbon composite nanoparticle was prepared by a one-pot thermal reaction using a mixture of ferrous oxalate and PTFE as precursor. FeF2 was obtained as the main phase according to the XRD patterns of the samples prepared in the present study. Furthermore, the FeF2 particle has a size of 50–100nm. Its electrochemical properties were studied in the 4.2–1.3V region at a current density of 60mAg−1. It exhibited an initial discharge capacity of 503.394mAhg−1 and still reserved discharge capacity of about 268.478, 211.34, 193.817 and 183.328mAhg−1 at the 2nd, 3rd, 10th, and 20th cycles, respectively.
