An Assessment of Blended Short Loop Recycled Graphite Electrodes Using X-Ray Micro-Computed Tomography

With various battery directives necessitating the composition of recycled electrode materials this study manufactures anodes containing various ratios of pristine and reclaimed graphite from end-of-life (EOL) cells. Two approaches that can be used to delaminate graphite are using ultrasonication (USD) and simple water delamination (WD). X-ray micro-computed tomography is used to characterize the graphite particles and show that particle fracturing is evident with both methods, but key structural metrics such as particle radius and diffusivity varied significantly.
