The Electrochemical Performance of Surface Protected LiFeBO3 Cathode Materials for Li-ion Batteries
Abstract:
The LiFeBO3 cathode materials for Li-ion batteries were prepared by means of solid reaction using lithium metaborate and ferrous oxalate as raw materials.The LiFeBO3 cathode materials were further coated by ethylene propylene copolymer(EPM).The samples were characterized by X-ray diffraction,scanning electron microscopy,and titration analysis.Electrochemical tests of materials showed that LiFeBO3 exhibited a higher discharge mass specific capacity.The electrochemical performance of the coated samples was demonstrated to be improved.Sample coated with 5% EPM had an initial capacity of 190 mA·h/g.It was found that only 4.2% capacity was lost after 50 charge/discharge cyclings at 0.5C.
