The Effect of Ni Doping Variations on the Microstructure and Conductivity of LiNixFe1-xPO4/C Composite Materials

This research uses the Solid State method to produce LiNixFe1-xPO4 /C Composite Materials with variation Ni ion doping are x= 0.01, 0.02, and 0.03, Characterization was carried out using XRD, PSA, SEM and EIS. The results of XRD analysis showed that LiFePO4, Li3Fe2PO4 and Fe2O3 phases were formed. T...

Description
Summary:This research uses the Solid State method to produce LiNixFe1-xPO4 /C Composite Materials with variation Ni ion doping are x= 0.01, 0.02, and 0.03, Characterization was carried out using XRD, PSA, SEM and EIS. The results of XRD analysis showed that LiFePO4, Li3Fe2PO4 and Fe2O3 phases were formed. The conductivity test results show that the conductivity of the LFP/C precursor is 10.24x10-4 S/cm, the LiNi0.01Fe0.99PO4/C precursor is 7.75 x10-4 S/cm, the LiNi0.02Fe0.98PO4/C precursor is 10.334 x10-4 S/cm, and the precursor LiNi0.03Fe0.97PO4/C was 4.87 x10-4 S/cm . With the highest conductivity value at LiNi0.02Fe0.98PO4/C precursor.
