This study introduces a multi-scale, multi-modal approach to the design and 3D printing of high-performance negative electrodes for lithium-ion batteries. Two types of printable inks were formulated using either alginate or carboxymethyl cellulose (CMC) as the primary binder, combined with styrene-butadiene rubber (SBR) and modified with a secondary fluid, 1-octanol. Rheological studies confirm that inks...
The limited duty cycles of EV batteries necessitate robust end-of-life strategies to prevent landfilling and enable responsible resource management. Recycling remains the ultimate fate for battery waste, yet current hydrometallurgical practices rely on often lengthy and energy-intensive methods, which provide a major incentive for the development of cost-effective, shorter-loop regeneration routes to recycle end-of-life electrodes....
The development of novel and efficient recycling techniques for rare earth elements (REEs) has prompted widespread interest owing to their limited availability and growing market demand. Herein, the rate of electrochemically assisted dissolution of NdFeB supermagnets in a deep eutectic solvent is improved through the application of ultrasound. Linear sweep voltammetry (LSV) with sonication showed...
Understanding the degradation of large format lithium-ion pouch cells – critical for electric vehicle applications – is vital to extend their lifetime and allow potential second-life application. Here, the impact on capacity fade and material degradation in two end-of-life cells, which were additionally subjected to accelerated aging to mimic extended use in second-life applications, were...
Separation of lithium and sodium is a topic of substantial scientific and industrial importance. Regarding Li/Na perchlorates, which are not only environmental hazards but also useful oxidants in chemical synthesis, an efficient Li–Na perchlorate separation method has not been reported due to lack of a ligand which can selectively coordinate with one of the two....
Niobium-based anodes are emerging as promising candidates for high-power lithium-ion batteries due to their high theoretical capacities, robust safety at high current densities, and excellent long-term cycling stability. In this respect Nb14W3O44 (NWO) has been attracting significant interest, and in this work, we investigate for the first time phosphorous-doping into this phase. Structural characterisation confirmed...
