Literature Review and Environmental Concerns Regarding Lithium-Ion Batteries

Abstract: This study investigates the environmental and technical challenges associated with the production, use, and recycling of lithium-ion batteries (LIBs), which are critical components in consumer electronics and electric vehicles (EVs). As the demand for LIBs continues to grow, the concerns related to the mining and processing of key materials like lithium, cobalt, nickel, and manganese are also increasing. The extraction and refining processes for these metals are energy-intensive and produce significant environmental impacts, including greenhouse gas emissions, toxic waste, and resource depletion. The review emphasizes the need for improved recycling technologies and sustainable practices to mitigate the environmental footprint of LIBs and secure a more sustainable supply chain for the future of clean energy storage solutions. This study also analyzes LIB components to assess the presence of environmentally hazardous metals and compounds. Advanced analytical techniques like X-ray fluorescence (XRF), inductively coupled plasma–optical emission spectroscopy (ICP-OES), and Fourier transform infrared (FTIR) spectroscopy revealed significant leaching of toxic elements and PFAS from battery parts, underscoring the environmental and health risks associated with improper disposal. The findings highlight the urgent need for improved recycling methods to mitigate these risks and enhance the sustainability of LIB use.
