Hypothesis
The study aims to assess the risks associated with the battery recycling process, particularly focusing on the hydrometallurgical methods used.
Conclusion
The study found that the use of sulfuric acid during lithium extraction poses the highest risk in the battery recycling process.
Supporting Evidence
- The study confirmed that the process using H2SO4 had the highest risk during lithium extraction.
- Accidents in battery recycling processes are increasing as the market for electric vehicles grows.
- Hydrometallurgical processes are commonly used in battery recycling but pose significant chemical risks.
Takeaway
This study looks at how batteries are recycled and the dangers involved, especially when using certain chemicals like sulfuric acid.
Methodology
The study generalized the battery recycling process and used a Risk Assessment Code (RAC) matrix to evaluate risks based on severity and probability of accidents.
Limitations
The study is qualitative and does not account for the quantities of chemicals used, which can affect risk levels.
