摘要
黄铁矿FeS2材料以其环保、价廉、克容量大、合适的禁带宽度,比能量高等优异特性被认为是锂电池的理想正极材料。文章就不同纯度的工业原料黄铁矿采用XRD,TG-DSC,BET,和SEM等技术进行了表征,并对其锂电性能进行了初步研究,不同纯度的黄铁矿其锂电性能有显著差异,纯度越高,锂电性能越佳。
The pyrite FeS2 is regarded as the ideal cathode materials for lithium battery because of its excellent characteristic of environmental-benign, low-cost, large capacity volume, proper band gap, and high specific energy. The natural pyrite FeS2 with different purity were characterized by XRD, TG-DSC, BET and SEM techniques and their electritic properties were examined. The higher the purity of FeS2, the better its electritic capacity.
