Abstract The market dynamics, and their impact on a future circular economy for lithium-ion batteries (LIB), are presented in this roadmap, with safety as an integral consideration throughout the life cycle. At point of end-of-life (EOL), there is range potential options—remanufacturing, reuse recycling. Diagnostics play significant role evaluating state-of-health condition batteries, improvements to diagnostic techniques evaluated. present, manual disassembly dominates EOL disposal,...
Cobalt and manganese were selectively leached from LiNMC using an oxalic acid : choline chloride deep eutectic solvent, resulting in a nickel-enriched solid residue.
Low value Mn based spinel from an EOL EV battery is selectively leached and upcycled to higher next generation cathode materials.
A direct recycling approach on NMC532 EV production scrap cathode material is demonstrated to allow regeneration along with Al current collector recovery.
In this paper, we demonstrate the successful incorporation of sulfate and borate into SrFeO3-δ, characterise effect on structure conductivity, with a view to possible utilisation as cathode material in Solid Oxide Fuel Cells. The low levels sulfate/borate is sufficient cause change from tetragonal cubic cell. Moreover, whereas heat treatment undoped SrFeO3-δ under N2 leads transformation brownmillerite Sr2Fe2O5 oxygen vacancy ordering, sulfate/borate-doped samples remain same conditions....
CO2 incorporation in solids is attracting considerable interest a range of energy-related areas. Materials degradation through also critical problem with some fuel cell materials, particularly for proton conducting ceramic cells. Despite this importance, the fundamental understanding mechanism lacking. Furthermore, growing use lower temperature sol gel routes design and synthesis new functional materials may be unwittingly introducing significant residual carbonate hydroxyl ions into...
Large-scale recycling and regeneration of lithium-ion cathode materials is hindered by the complex mixture chemistries often present in waste stream. We outline an efficient process for separation phases within a blended cathode. demonstrate efficacy this approach using material from first generation 1 (Gen 1) Nissan Leaf end-of-life (40,000 miles) cell. Exploiting different stabilities transition metals acidic media, we that ascorbic acid selectively leaches low-value spinel electrode...
In this paper we report the successful incorporation of sulfate into triple layer (n = 3) Ruddlesden-Popper system Sr4Fe3O10-δ, with characterisation these materials by X-ray diffraction, Mössbauer spectroscopy, and conductivity measurements. Significantly, SO42- middle perovskite leads to stabilization phase, which cannot be prepared without doping, thus highlighting potential oxyanion doping as a strategy synthesise new phases interest for solid oxide fuel cells.
The increase in the use of electric vehicles (EVs) will ultimately lead to an number end-of-life lithium-ion batteries (LIBs) that need be recycled. A particular challenge concerns how deal with low value cathodes, such as LiMn2O4 (LMO). To this end, paper investigates recycling cathode material from Gen 1 Nissan Leaf (2011 model, 40,000 miles) which contains a mixture spinel (LMO) and Ni-rich layered oxide (LO). Citric acid was employed selectively leach LMO into solution while leaving...
This work reports on an oxyanion containing Sr-Fe-O perovskite-related layered oxide system related to the "0201-1201" type material Sr4.5Cr2.5O9. Using solid state synthesis, we successfully incorporate SO42- and CrO42- give Sr4.5Fe2(S/Cr)0.5O9±δ, with X-ray neutron diffraction used analyse structure of these materials. Neutron experiments combined 57Fe Mössbauer spectroscopy absorption show not only successful incorporation, but also that systems have ability accommodate excess...
