Abstract
Although the synthesis is not so easy, LiFeSO4F, a high-voltage iron-based cathode, is attractive by virtue of its low cost and small environmental impact. We prepared amorphous xLiF-FeSO4 (1â¯â¤â¯xâ¯â¤â¯2) using the dry ball-milling method. Moreover, we succeeded to synthesize tavorite-type LiFeSO4F by sintering amorphous LiF-FeSO4 at 280â¯Â°C. Amorphous 1.3LiF-FeSO4 exhibited the highest reversible capacity, of about 130â¯mAhâ¯gâ1, among all the xLiF-FeSO4 series (1â¯â¤â¯xâ¯â¤â¯2), with an average voltage of 3.5â¯V. In addition, we found that the obtained amorphous xLiF-FeSO4 cathodes have excellent cyclability and rate capability, also.
