Improper disposal of lithium battery poses multiple risks. Toxic heavy metals such as lithium, cobalt, and nickel can seep into soil and water, contaminating ecosystems and endangering human health. Additionally, lithium extraction is an energy-intensive process that leads to deforestation, water shortages, and high carbon emissions. Another critical issue is fire hazards. Lithium ion batteries contain highly reactive materials, and if damaged or improperly stored, they can overheat and ignite, posing risks in landfills and waste facilities. These concerns highlight the need for a robust recycling system to prevent environmental damage and promote sustainability.
