摘要：

Lithium iron phosphate (LiFePO4) is frequently used for Li-ion battery cathode. LiFePO4 has the high specific capacity at 170 mAhg(-1), stable voltage at 3.45 V, stable structure, cheap, and low toxicity. The objective of this research is investigating the effect of precursor concentration on the electrical properties of LiFePO4 prepared by solvothermal method. LiOH, FeSO4, H3PO(4), and citric acid were used as the precursors. The LiOH concentration was varied from 0.3 M to 1.8 M. The Fourier Transform Infrared Spectroscopy (FTIR) measurement identified the Fe-O, O-P-O, and P-O bonds which corresponding to LiFePO4. The result of 4-point probe measurement shows that, among the prepared samples, the sample from the precursor concentration of 1.8 M has the highest electrical conductivity.
