Accurate quantification of the lithium-bearing EnAM is crucial to evaluate the results of the conditioning and assess valorization. However, reliably quantifying the phase assemblage in slag remains challenging due to its chemical and microstructural properties. Here, a conditioned LIB-recycling slag is investigated using complementary bulk, local, and structural analytical methods. Rietveld analysis-based phase quantification, employing internal standard method, spiking, and micronizing, is directly compared with quantitative image analysis of backscattered electron images. The bulk and local chemical composition of the slag is investigated by wavelength-dispersive X-ray fluorescence spectroscopy, inductively coupled plasma optical emission spectroscopy, and electron probe microanalysis. The slag exhibits an average Li<sub>2</sub>O content of 3.33 mass%. Rietveld quantification yields 26.2 mass% of β-eucryptite, the present lithium-bearing EnAM, with a low random error, calculated using standard addition. However, quantitative image analysis returned 20.8 mass% ±2.5 mass% (2σ) β-eucryptite. The overestimation by Rietveld method may be attributed to microabsorption effects caused by differences in X-ray attenuation between phases.

Adding to the challenge, device optimization has been overly focused only on highest efficiency, generally incorporating processes at odds with scale-up and durability efforts that precede commercialization.
