Abstract

Baterai NMC merupakan salah satu jenis baterai berbahan nikel yang sedang meningkat permintaanya salah satunya di industri electric vehicle. NMC dibuat dari nikel kualitas tinggi yang dihasilkan dari bijih sulfida berupa nickel (II) sulfate hexahydrate (NiSO4.6H2O). Namun jumlah bijih sulfida yang semakin sedikit memicu kita untuk menghasilkan NiSO4.6H2O dari bijih laterit yang jumlahnya lebih banyak di alam. Maka dari itu penelitian ini dilakukan dengan tujuan untuk menghasilkan nikel sulfat berupa NiSO4.6H2O dari bijih laterit melalui proses leaching. Variasi yang dilakukan adalah variasi rasio massa ferronickel per volume H2SO4 dengan variasi rasio 1/40, 1/50, 1/60, 1/70 dan 1/80. Untuk mengetahui presentase ekstraksi Ni pada proses leaching dilakukan pengujian AAS. Untuk mengetahui komposisi kimia, senyawa yang terbentuk serta menghitung yield Ni pada produk dilakukan pengujian XRD dan EDX. Didapatkan presentase ekstraksi Ni yang paling baik adalah sebesar 100% pada rasio 1/70. Pada setiap variasi rasio solid/liquid terbentuk senyawa NiSO4.6H2O dengan kadar Ni tertinggi sebesar 16,17% pada rasio 1/80 sehingga nilai yield Ni tertinggi diperoleh sebesar 93.3%. ============================================================ ======================================== The NMC battery is a type of nickel-based battery whose demand is increasing, one of which is in the electric vehicle industry. NMC is made from high-quality nickel produced from sulfide ore in the form of nickel (II) sulfate hexahydrate (NiSO4.6H2O). However, the less amount of sulfide ore we have to produce NiSO4.6H2O from laterite ore which is more abundant in nature. Therefore, this research was conducted to produce nickel sulfate in the form of NiSO4.6H2O from the ore and then through the leaching process. The variations made were variations in the mass ratio of ferronickel per volume of H2SO4 with variations in the ratio of 1/40, 1/50, 1/60, 1/70 and 1/80. To see the percentage extraction of Ni in the release process, the AAS tester was carried out. To find out the chemical composition, compounds formed and to calculate the Ni yield in the product, XRD and EDX tests were carried out. The best percentage extraction of Ni was obtained at 100% at 1/70 ratio. In each solid/liquid ratio variation, a NiSO4.6H2O compound is formed with the highest Ni content of 16.17% at a ratio of 1/80 so that the Ni yield value is obtained at 93.3%.
