Electric Cars Are Not As Harmless As They Seem. Their Batteries Can Cause Great Environmental And Social Damage
Electric cars are known for being allies of the environment, as they use clean energy and thus do not directly pollute the atmosphere. Their batteries are expensive, emit carbon during production, and rely on lithium, a resource that is scarce in nature and must be extracted through mining. Additionally, the world’s lithium sources are located in conflict regions, such as the Congo, located on the African continent.
Damage Caused by Lithium, Used in the Production of Electric Car Batteries
In addition to being a rare element that must be mined in distant and conflict-ridden areas, 2.1 million liters of water are needed for the extraction and refining of each ton of lithium, enough to produce batteries for just about 80 electric vehicles. To worsen the environmental issue, the lithium contained in the rocks must be separated using highly toxic chemicals, such as sodium carbonate, bases, and acids. The release of these chemicals through the leaching process, spills, or atmospheric emissions endangers local communities and ecosystems.
High Cost of Electric Car Batteries Is Another Negative Factor
According to researcher Carolina Pineda Castro from the Electric Vehicle Study Laboratory (Leve) at the State University of Campinas (Unicamp), several obstacles must be overcome to make the lithium battery production chain less complex and cheaper. “The COVID-19 pandemic and the Russia-Ukraine war affected battery prices, which had been declining,” she states. “This is because the price of metals such as cobalt, lithium, and nickel increased, raising serious concerns about the supply chain,” she adds.
