[PDF Version]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 manufacturing processes.
Although manufacturing incorporates several safety stages throughout the aging and charging protocol, lithium-ion battery cells are susceptible to fire hazards. These safety challenges vary depending on the specific manufacturing environment, but common examples include:
For batteries, a number of pollutive agents has been already identified on consolidated manufacturing trends, including lead, cadmium, lithium, and other heavy metals. Moreover, the emerging materials used in battery assembly may pose new concerns on environmental safety as the reports on their toxic effects remain ambiguous.
