Abstract

Motor vehicles are one of the main factors affecting global temperature rise. It has triggered the automotive industry to develop an environmentally-friendly vehicle, one of which is by the development of electric vehicles (EV). EV itself uses fuel in the form of batteries. The widely used battery type is the Lithium-ion battery which has Nickel Manganese Cobalt (NMC) cathode. One of the raw materials for NMC batteries is nickel sulfate. Unfortunately, nickel sulfate processing uses a rare nickel sulfide ore. Therefore, it is necessary to research to produce nickel sulfate by using a type of laterite nickel. Indonesia has an abundant reserve of laterite nickel ore. The processing process uses the smelting-oxidation refining-leaching route. The leaching process was carried out using H2SO4. Then, to eliminate the impurities, a neutralization process was carried out using a NaOH solution to obtain a pH of 2.5. The purpose of this research itself was to determine the effect of variations in H2SO4 concentration on the chemical composition, yield, and compound of The product produced in the form of NiSO4.6H2O. H2SO4 was used with a variation concentration of 1M, 1.5M, 2M, 2.5M, and 3M. The results obtained showed that the most optimal yield was obtained at 2M concentration variation. The presence of FeS compounds in the product proved that the leaching process was not running optimally. The H2SO4 concentration of 2.5M obtained the highest nickel content. NiSO4.6H2O compound itself can be formed in all variations.
