Study Notes

Quantifying Lithium-Ion Battery Health Impacts

Lithium-ion batteries (LIBs) are criticized for negative social impacts, especially concerning child labor and harsh conditions during cobalt extraction.
This study focuses on the human health impacts, specifically using disability-adjusted life years (DALY) to quantify potential life-cycle impacts of a nickel-manganese-cobalt (NMC 811) LIB cell.
A cradle-to-gate life-cycle assessment (LCA) is performed, using one LIB cell as the functional unit and assessing health impacts from emissions and occupational accidents.
Two fatality scenarios for artisanal cobalt mining in the Democratic Republic of Congo (DRC) are considered: a high scenario (2000 fatalities/year) and a low scenario (65 fatalities/year).
Occupational accidents in DRC artisanal cobalt mines contribute significantly to the total life-cycle health impacts (13% with the high fatality rate), but emissions from nickel sulfate and copper foil production contribute more (30% and 20%, respectively).
The study highlights the importance of replacing copper foil, reducing metal extraction emissions, increasing recycled metal content, and improving occupational standards in DRC mines to lessen health impacts.

Health Impacts and Methodology

Artisanal cobalt mining in the DRC has been linked to child labor, long working hours, harsh conditions, and exposure to harmful substances.
The study uses a life-cycle impact pathway approach to assess health impacts.
Disability-adjusted life years (DALYs) were calculated for both emissions and occupational accidents.
Emissions and water use have the greatest contribution to overall health impacts.

Occupational Accidents

Occupational accidents in other areas of the product system contribute substantially less to the potential impact than accidents in artisanal cobalt mining.
Accidents in artisanal mining are more significant due to specific circumstances at the production site.

Potential Improvements

Lowering cobalt content in LIB cells (e.g., transitioning to NMC 811 from NMC 111) might offer a viable improvement strategy.
Investigating different materials as alternatives to copper for anode current collectors.
Enhancing recycling procedures for metals like cobalt and nickel.
Improving occupational standards and safety measures in artisanal cobalt mines to lessen accident rates.
