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.
