“…For example, niobium-based negative electrodes, although still at TRL 5 100 , can have capacities as high as 225 mAh g −1 at 34.3 mA g −1 and promise average cell discharge voltages of 2.3 V, which would result in higher energy densities than LTO-based cells 101 , but still lower than graphite-based cells. A near-monopoly of Nb supply could pose a risk to adoption 102 , and it is important to consider which technique is used for ore refinement and Nb purification 103 . Similarly to LTO, commercial adoption of these cells could be hampered by the higher $ kWh −1 cost compared to cells with graphite-based negative electrodes.…”

In the field of lithium-based batteries, there is often a substantial divide between academic research and industrial market needs. This is in part driven by a lack of peer-reviewed publications from industry. Here we present a non-academic view on applied research in lithium-based batteries to sharpen the focus and help bridge the gap between academic and industrial research. We focus our discussion on key metrics and challenges to be considered when developing new technologies in this industry. We also explore the need to consider various performance aspects in unison when developing a new material/technology. Moreover, we also investigate the suitability of supply chains, sustainability of materials and the impact on system-level cost as factors that need to be accounted for when working on new technologies. With these considerations in mind, we then assess the latest developments in the lithium-based battery industry, providing our views on the challenges and prospects of various technologies.

“…Niobium (Nb) is a rare metal used in the production of high-strength low-alloy steel which is decrypted as HSLA (Sanz et al, 2022). Along with that, it is used in the industry of ferroniobium and it constituted more than 90% of niobium production.…”

This study was aimed to investigate the development of a technology for the extraction of niobium pentaoxide and ammonium sulfate from titanium-magnesium production waste, specifically, the sublimates of dust chamber into concentrate in the form of niobium pentoxide. Optimal conditions for washing the niobium hydroxide precipitate by repulpation with hot (60-70°C) distilled water, drying at 200°C for 6 hours were determined. The influence of temperature and duration of the process was studied. Optimal conditions for the dynamic desorption of niobium from saturated ionite (Purolite A100) was determined. The results further indicated that the optimum quantity of the solution of desorption with sulfuric acid was equal to 5.5% and ammonium oxalate was equal to 4%, while temperature and the flow rate of the desorbing solution was 22-27°C and 6 rpm, respectively. The study of the precipitation of niobium from sulfuric acid desorbates showed that the interaction of niobium ions with ammonia takes place at a low rate. The degree of precipitation of niobium hydroxide equal to 99.6% was achieved in 7 hours of agitation of the suspension at a temperature of 22-25°C.
