The differentiated meteorite, Mundrabilla, exhibits a rare structure of primary kamacite/taenite, and at least 25 volume % of sulfide (troilite and daubreelite). The structure has been investigated in three dimensions using the technique of gamma-ray computed tomography (CT) with a radioactive Co isotope as the source of the flux. Using CT, a 50 kg slab with dimensions 12.6 x 8.2 x ~70 cm has b...

Following earlier work of Huggins and Nix [Ionics 6, 57 (2000)], several recent theoretical studies have used the shrinking core model to predict intraparticle Li concentration profiles and associated stress fields. A goal of such efforts is to understand and predict particle fracture, which is sometimes observed in degraded electrodes. In this paper we present experimental data on LiCoO2 and g...

The first phase of this work aims to use the right additive nano-fillers choices, such as exfoliated Graphite (ExG), increasing mechanical, electrical, and thermal performances. In work, we are interested in quantifying effect particles' size on a polymer matrix's performance. For this, three sets polymers filled with Graphite, characterized by particle sizes, called meshes 50, 100, 150, were i...

The comminution of spent lithium-ion batteries (LIBs) produces a powder containing the active cell components, commonly referred to as “black mass.” Recently, froth flotation has been proposed treat fine fraction black mass (<100 µm) method separate anodic graphite particles from cathodic lithium metal oxides (LMOs). So far, pyrolysis considered an effective treatment remove organic binders ...
