一种新型电池阴极材料的制备与表征

PREPARATION AND CHARACTERIZATION OF NOVAL CATHODE

摘要: 介绍了聚环氧乙烷(PEO)/ Li_<em>xV_2-δO_4-δ纳米复合材料的制备工艺过程。通过X射线衍射、示差扫描量热分析、红外光谱等仪器进行分析,结果表明,PEO大分子插入到Li_<em>xV_2-δO_4-δ片层间,使层间距增大了0.42 nm,并且PEO在片层间的运动能力受到了一定的限制。

Abstract: PEO/Li_<em>xV_2-δO_4-δ nanocomposite was prepared by the solution intercalation method. Powder X-ray diffraction, differential scanning calorimetry and infrared spectrum analysis show that PEO chains intercalate Li_<em>xV_2-δO_4-δ galleries and expand the lattice lamella by 0.42 nm. The movement ability of PEO is also restricted.
