1. 毕业设计(论文)的内容和要求

橄榄石型正极材料磷酸锰锂( LiMnPO4)与同一类型的LiFePO4有着相同的理论比容量( 170 mAh/g),但其拥有更高放电平台( 4.1 V vs Li/Li ,LiFePO4为3.4 V vs Li/Li ),因而具有潜在的高能量密度。除此之外磷酸锰锂原料价格低廉、资源丰富和对环境无污染等优势也使得该材料正受到越来越多的关注。但低电子电导率( σe 10-10 Scm-1 at 300 K)和低Li 扩散系数( DLi 10-14 cm2S-1 )使得LiMnPO4的实际电化学性能受到很大影响。因而如何优化合成工艺以提高LiMnPO4的电化学性能是对其进行电化学改性的主要目的,对其在电子器械和混合动力汽车等方面的运用有着非常重要的意义。

本论文要求查阅大量文献和相关资料,要研究利用固相法制备LiMnPO4正极材料。摸索出制备过程的一些最佳的工艺条件,以及对粉末X射线衍射分析、高分辨扫描电子显微镜(SEM)检测、并测试其导电性能。撰写出论文,并答辩。
