Abstract

Penelitian ini berjudul “Pengaruh Variasi Doping Ni Terhadap Mikrostruktur dan Konduktivitas Material Katoda LiNixFe1-xPO4 ”. Penelitian ini menggunakan metode Solid State. Variasi yang digunakan dalam penelitian ini adalah doping Ni dengan x= 0.01, 0.02, dan 0.03, Karakterisasi dilakukan dengan menggunakan XRD, PSA, SEM dan EIS. Hasil analisis XRD menunjukkan bahwa terbentuk fasa LiFePO4, Li3Fe2PO4 dan Fe2O3. Hasil Uji Konduktivitas menunujukan bahwa konduktivitas pada prekursor LFP/C sebesar 10.24x10-4 S/cm, prekursor LiNi0.01Fe0.99PO4/C sebesar 7.75 x10-4 S/cm, prekursor LiNi0.02Fe0.98PO4/C sebesar 10.334 x10-4 S/cm, dan prekursor LiNi0.03Fe0.97PO4/C sebesar 4.87 x10-4 S/cm . Dengan nilai konduktivitas tertinggi pada prekursor LiNi0.02Fe0.98PO4/C. =========================================================================================================== The research entitled "The Effect of Ni Doping Variation to the microstructure and conductivity of Cathode material LiNixFe1-xPO4 ”. This research used solid state method.The variations that were used in this method is Ni doping with x= 0.01, 0.02, and 0.03, characterization is done by using XRD, PSA, SEM dan EIS. The analysis results of XRD indicates that the phase is formedLiFePO4, Li3Fe2PO4 dan Fe2O3. The conductivity test results shows that the conductivity of the precursor LFP/C amount 10.24x10-4 S/cm, precursor LiNi0.01Fe0.99 PO4/C amount 7.75 x10-4 S/cm, precursor LiNi0.02Fe0.98PO4/C amount 10.334 x10-4 S/cm, and precursor LiNi0.03Fe0.97PO4/C amount 4.87 x10-4 S/cm .With the highest conductivity value on the precursor LiNi0.02Fe0.98PO4/C.
