Abstract |
We have synthesized a Cryolite type iron hexafluoroferrates by mild chemistry complex formation reaction. For the first time their electrochemical properties as positive electrode materials in recharg...eable batteries were studied. The alpha-Li3FeF6 delivered a 116 mAh/g reversible capacity at an average discharge voltage of 3.0 V maintaining good capacity retention of about 30 cycles at a 0.2 mA/cm2 rate. The preliminary results are reported.show more
