One of the efforts to meet the limited supply of fossil fuels is to replace the use of electric vehicles. Lithium batteries are one of the energy storage media that are environmentally friendly and cost-effective. Lithium batteries contain lithium ions. There are two sources for obtaining lithium ions as raw materials for batteries: used and natural resources. A natural resource that can potentially contain lithium ions is Sidoarjo mud. This research aims to determine the percentage efficiency of lithium extraction by the hydrometallurgical method. Factors affecting the extraction process include temperature, extraction time, solid-liquid ratio, and concentration of lactic acid solvent. The best leaching conditions were obtained at a temperature of 90oC and a concentration of 0.9 M lactic acid of 69.82%..
