The speciation of rhodium(III) chlorido complexes was investigated in ethylene glycol, in the presence and absence of lithium chloride, by rhodium-103 NMR and EXAFS spectroscopy. All major rhodium(III) complexes were identified based on their species-specific isotopologue and isotopomer patterns. EXAFS analysis confirmed the results deduced from the rhodium-103 NMR spectra. The strikingly different shifting behavior observed with increasing lithium chloride concentration was linked to the established behavior of r…

<ns3:p>Background To counter climate change, it will be necessary to have a major transition of both energy and mobility systems. Electrification of mobility is one essential part of the solution. Nearly 65% of Cobalt is mined in Africa (e.g. Central African Republic and Democratic Republic of the Congo) and this dependency makes Europe vulnerable. It is essential to develop an efficient and robust technology capable of recycling this kind of waste. Methods Due to the risk of supply and to decrease the dependency …

Abstract A significant consequence of the green transition is the growing demand of lithium-ion batteries (LIBs), as they are essential for electrical vehicles. In turn, the demand for the raw materials that are needed to produce LIBs is increasing. A common LIB cathode type for electrical cars is lithium nickel manganese cobalt oxide (NMC). Since cobalt is currently considered as a critical raw material, nickel-rich NMC cathodes are now designed with lower cobalt contents. The synthesis of these new NMC types req…
