Recyclage de métaux venant d'accumulateurs NiMH : développement d'extractions liquide-liquide sélectives à partir de liquides ioniques by Matthieu Gras( )

1 edition published in 2018 in English and held by 2 WorldCat member libraries worldwide

Nickel-metal hydride (NiMH) batteries are currently dominating the market of energy storage in hybrid electric vehicles. 1 billion cells are estimated to be produced each year. In their end-of-life, these electronical wastes exhibit low recycling rates, despite the fact that NiMH batteries contain high amounts of valuable and strategic metals. Two main metal families coexist as an intermetallic compound in negative electrodes: transition metals (TM) (Ni, Co, Mn and Fe) and rare earth elements (REE) (La, Ce, Nd and Pr). Among TM, cobalt exhibits the highest criticality rate. Indeed, natural ores will not cover the increasing cobalt demand linked to emerging technologies. REE produced at more than 97 % in China are at the centre of European Union's preoccupations. To tackle economic and environmental issues, this project, supported by the labex CEMAM is a partnership between the company Recupyl® and the academic laboratory LEPMI. It aims at investigating on low environmental impact routes for the recycling of metals present in real spent NiMH batteries. This requires the replacement of volatile organic compounds by ionic liquids, respecting the principles of 'green chemistry'. Based on innovative extraction and recovery processes of elements by hydrometallurgy and electrochemistry, we propose a flowsheet for the valorisation of metals from those batteries
Vers une méthode de recyclage et de valorisation des aimants permanents à base de terres rares par électrochimie en milieux liquides ioniques by Céline Bonnaud( )

1 edition published in 2017 in French and held by 2 WorldCat member libraries worldwide

Rare earth elements (REE) are currently essential for new technologies development; from everyday life objects to green energies devices, they are especially used in permanent magnets. NdFeB and SmCo permanent magnets represent more than 50% of the REE market and offer a high recycling opportunity. The present study focuses on their recycling, mainly via electrochemistry in ionic liquid medium (IL), which enables to reach the reduction potentials of REE (< -2 V vs. ENH).Samarium, neodymium, dysprosium, praseodymium and cobalt were successfully electrodeposited in [C1C4Pyrr] [Tf2N] according to a potentiometric method at 25 ° C and on a glassy carbon electrode.Two general recycling methods are finally proposed and have been applied to industrial permanent magnets. The first uses only electrochemistry and is based on a first magnet electrodissolution step in the IL followed by a selective electroplating to recover the transition metals. Electrodeposition of REE could then be possible. The second method starts by an acid leaching of the magnet in order to efficiently separate the transition metals from REE via the formation of phosphate salts. Dissolution of the salts obtained in LI would then enable to electrodeposit the metal ions

Mechanism of ionic-liquid-based acidic aqueous biphasic system formation1( )

1 edition published in 2018 in English and held by 1 WorldCat member library worldwide

Abstract : This work represents a major contribution to the understanding of ionic liquid-based acidic aqueous biphasic system formation and application. Abstract : Ionic-liquid-based acidic aqueous biphasic systems (IL-based AcABS) represent a promising alternative to the solvent extraction process for the recovery of critical metals, in which the substitution of the inorganic salt by an acid allows for a 'one-pot' approach to the leaching and separation of metals. However, a more fundamental understanding of AcABS formation remains wanting. In this work, the formation mechanisms of AcABS are elucidated through a comparison with traditional aqueous biphasic systems (ABS). A large screening of AcABS formation with a wide range of IL identifies the charge shielding of the cation as the primary structural driver for the applicability of an IL in AcABS. Through a systematic study of tributyltetradecylphosphonium chloride ([P44414]Cl) with various chloride salts and acids, we observed the first significant deviation to the cationic Hofmeister series reported for IL-based ABS. Furthermore, the weaker than expected salting-out ability of H3 O + compared to Na + is attributed to the greater interaction of H3 O + with the [P44414] + micelle surface. Finally, the remarkable thermomorphic properties of [P44414]Cl based systems are investigated with a significant increase in the biphasic region induced by the increase in the temperature from 298 K to 323 K. These finding allows for the extension of ABS to new acidic systems and highlights their versatility and tunability
