Lithium is used for many purposes, including treatment of bipolar disorder. While lithium can be toxic to humans in doses as low as 1.5 to 2.5 mEq/L in blood serum, the bigger issues in lithium-ion batteries arise from the organic solvents used in battery cells and byproducts associated with the sourcing and. Much of the world's lithium is extracted by tapping into underground “brine” deposits, pumping water rich in lithium salts into large evaporation ponds. Approximately 500,000 gallons of brinemust be extracted to produce one metric ton of lithium, which significantly impacts the. The cathode material in some high-density lithium-ion batteries includes as much as 80% nickel. Coal-fired nickel smelters, such as the ones found in Indonesia, release carcinogenic sulfur dioxide into the air, and communities near nickel mines and smelting operations. Lithium isn't the only problematic metal in lithium-ion batteries. Cobalt, which can constitute a significant amount of the cathode material, is toxic when inhaled or consumed at above-average levels. Cobalt toxicity can lead to chronic respiratory and cardiovascular diseases. The organic liquids used in most electrolyte formulations are both mildly toxic when ingested and can irritate the eyes and skin. Inhaling their vapors may cause nausea, vomiting, or. Some types of Lithium-ion batteries such as contain metals such as, and, which are toxic and can contaminate water supplies and ecosystems if they leach out of landfills. Additionally, fires in landfills or battery-recycling facilities have been attributed to inappropriate disposal of lithium-ion batteries. As a result, some jurisdictions require lithium-ion batteries to be recycled. Despite the environmental cost of improper disposal of lithium-ion batte.
