Using ICP-OES to Assess Elemental Purity in Battery Recycling
Author(s):
This episode provides expert insights into safely transforming shredded lithium-ion batteries into reusable metals using ICP-OES.
This episode considers the complex processes involved in handling and processing black mass after lithium-ion batteries are shredded, emphasizing environmental, safety, and regulatory considerations. Panelists highlight how thermal and hydrometallurgical treatments recover critical metals like nickel, cobalt, and manganese, while ICP-OES plays a central role in monitoring air, water, and solid waste to ensure safe and efficient recycling practices. The discussion also covers how recyclers comply with the Restriction of Hazardous Substances (RoHS) Directive when reintroducing recovered metals into new battery production.
The episode delves into the occupational and environmental challenges of black mass processing, including the hazards posed by fine powders containing reactive fluorine and heavy metals. Experts discuss safety strategies such as proper PPE, respirators, gloves, protective clothing, and water-spray systems to minimize airborne particulates and fire risks.
Key takeaways from this episode include:
- Methods for processing black mass through thermal and chemical treatments to extract battery-grade metals.
- Role of ICP-OES in monitoring elemental content in air, water, and solid waste for safe recycling.
- Environmental and occupational safety considerations when handling nanoparticulate and fluorine-rich materials.
- Ensuring RoHS compliance by analyzing recovered metals before reintroduction into manufacturing.
- Best practices for mitigating dust, fire, and chemical hazards during battery recycling operations.
