摘要

本研究的目的是在x = 0时合成LiFe1-xNixPO4/C;0.05;0.07;0.09微波辐照辅助回流法。目的是提高Li+化合物的电子电导率和反应速率。结果表明，该方法在Pnma空间群中成功合成了具有正交晶型结构的LiFePO4/C和LiFe1-xNixPO4/C。最佳回流微波辐照时间为10 min，随着Ni掺杂量的增加，晶格参数减小，电池体积减小。晶粒尺寸为21.42 ~ 22.62 nm，颗粒表面不规则。LiFe0.93Ni0.07PO4/C的电导率最高，为5.45 × 10-7 S/cm。

SYNTHESIS OF LiFe1-xNixPO4/C USING THE REFLUX WITH MICROWAVE IRRADIATION METHOD

The aim of this study was to synthesize LiFe1-xNixPO4/C with x = 0; 0.05; 0.07; 0.09 using the reflux method assisted by microwave irradiation. The goal was to increase the value of the electronic conductivity and reaction rate of Li+ compounds. The results showed that the method successfully synthesized LiFePO4/C and LiFe1-xNixPO4/C with an orthorhombic crystal structure in the Pnma space group. The optimum reflux-microwave irradiation time was 10 minutes, and increasing moles of Ni doping lead to a decrease in the lattice parameters cell volume. The crystalline size ranged from 21.42–22.62 nm, and the surface of the compound particles was irregular. The compound LiFe0.93Ni0.07PO4/C had the highest conductivity (5.45 × 10-7 S/cm).

期刊介绍： RASĀYAN Journal of Chemistry [RJC] signifies a confluence of diverse streams of chemistry to stir up the cerebral powers of its contributors and readers. By introducing the journal by this name, we humbly intent to provide an open platform to all researchers, academicians and readers to showcase their ideas and research findings among the people of their own fraternity and to share their vast repository of knowledge and information. The journal seeks to embody the spirit of enquiry and innovation to augment the richness of existing chemistry literature and theories. We also aim towards making this journal an unparalleled reservoir of information and in process aspire to inculcate and expand the research aptitude.
