Abstract

fetched live from OpenAlex

The growing demand for energy storage batteries, driven by the need to alleviate global warming and reduce fossil fuel dependency, has led to environmental concerns surrounding spent batteries. Efficient recycling of these batteries is essential to prevent pollution and recover valuable metal ions such as nickel (Ni 2+ ), cobalt (Co 2+ ), and manganese (Mn 2+ ). Conventional hydrometallurgical methods for battery recycling, while effective, often involve harmful chemicals and processes. Natural polyphenols offer a greener alternative due to their ability to coordinate with metal ions. However, optimizing polyphenol selection for efficient recovery remains a labor-intensive challenge. This study presents a strategy combining natural polyphenols as green precipitants with the power of GPT-4, a large language model (LLM), to enhance the precipitation and recovery of metal ions from spent batteries. By leveraging the capabilities of GPT-4 in natural language processing, we enable a dynamic, iterative collaboration between human researchers and the LLM, optimizing polyphenol selection for different experimental conditions. The results show that tannic acid achieved precipitation rates of 94.8, 96.7, and 96.7% for Ni 2+, Co 2+, and Mn 2+, respectively, outperforming conventional methods. The integration of GPT-4 enhances both the efficiency and accuracy of the process, ensuring environmental sustainability by minimizing secondary pollution and utilizing biodegradable materials. This innovative strategy demonstrates the potential of combining artificial intelligence-driven analysis with green chemistry to address battery recycling challenges, paving the way for more sustainable and efficient methods.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
