Abstract

Peningkatan performa sifat elektrokimia baterai lithium iron posphate (LiFePO4) dapat dilakukan dengan beberapa metoda yaitu pelapisan karbon, reduksi ukuran partikel dan doping. Telah berhasil di sintesis material katoda LiFePO4/C dengan doping Ni wt 1% menggunakan metode solid state dengan suhu kalsinasi 750°C dalam atmosfir udara dan beberapa variasi waktu penahanan yaitu 8, 9, 11, 12, dan 13 jam. sampel dikarakterisasi dengan pengujian XRD, SEM, PSA, dan konduktivitas listrik. Hasil menunjukan bahwa terdapat dua fasa pengotor yang muncul yaitu LiFeP2O7 dan Li3PO4. Hasil pengujian konduktivitas menunjukan bahwa konduktivitas listrik meningkat seiring bertambahnya kandungan fasa LiFePO4. =============== Increasing electrochemical characteristic of lithium iron posphate (LiFePO4) can do in various method such as carbon coating, particle size reduction, and cation doped. LiFePO4 Ni doped were synthesized by solid state method, and calcination at 750°C in the air atmosphere with various holding time. Samples characterized by XRD, SEM, PSA, and conductivity test. The result show that the samples have two impurity phases such as LiFeP2O7 and Li3PO4. The result of conductivity test show that increasing of electrical conductivity proportional to increase of LiFePO4 phase content.
