LiCoPO4中碳与Co2P杂质含量的确定
Determination of content of carbon and Co2P impurities in LiCoPO4
摘要
Abstract
A method to analyze the content of carbon and cobalt phosphide(Co2P) impurities in lithium cobalt phosphate(Li-CoPO4) by acid leaching to dissolve LiCoPO4 was presented. The results of XRD analysis showed that the product was Co2P phase after leached by dilute HQ, the product was carbon material after leached by dilute HNO3. The content of carbon in synthesized Ii-CoPO4/C composite was 5.4%, the content of Co2P impurity was 5.3% by the determination with the mentioned method. The particle size of Synthesized sample was about 0.5μm,the 0.2 C specific discharge capacity was 75 mAh/gd(LiCoPO4+Co2+P+C).关键词
