Sustainable Working Life Within the Production and Recycling of Lithium-Ion Batteries for Electric Vehicles (GreenWorkLiB)

Achieving the EU’s climate goals by 2050 requires a rapid transition to a resource-efficient and circular economy. The electrification of transport increases the demand for rechargeable lithium-ion batteries (LiBs), where lithium–nickel–cobalt–manganese (Li-NMC) is the predominant cathode technology in the European automotive sector. Large-scale facilities for LiB production and recycling are emerging worldwide, bringing not only technical challenges but also challenges regarding healthy and safe working environments. Current knowledge on occupational exposure and health risks in the LiB industry is limited and largely based on evidence from other occupational settings. However, the LiB industry involves legacy and new combinations of metals and chemicals in novel contexts. Some of these substances have well-known adverse health effects, and combined exposure may increase their absorption and toxicity. Although processes are often highly specialised and automated, manual handling tasks remain, which put workers at risk of exposure. Important knowledge gaps remain regarding exposure levels, exposure pathways, dermal and systemic uptake, combined exposures, and potential health effects among workers. This perspective paper discusses current exposure scenarios and health risks in LiB production and recycling, identifies key knowledge gaps, and highlights future research needs to support evidence-based occupational risk management. To address several of these challenges, the GreenWorkLiB initiative applies a multidisciplinary approach combining exposure assessment, biomonitoring, and occupational medicine. The initiative investigates exposure pathways via air and skin, internal dose through biomonitoring, and potential health effects among workers in LiB production and recycling. The results can support the assessment of human health and safety within the EU’s Safe and Sustainable by Design (SSbD) framework and contribute to safe and sustainable working environments in the LiB industry.
