Niobium pentoxide (Nb2O5) is a promising anode candidate for lithium-ion batteries due to its high theoretical capacity, excellent rate capability, and safe working potential. However, its inherent low conductivity limits its practical application in fast-charging scenarios. In this work, we develop an ultrathin carbon-coated two-dimensional T-Nb2O5 nanosheet composite (T-Nb2O5@UTC) through a facile solvothermal reaction and subsequent CVD acetylene decomposition. This unique design integrates a two-dimensional nanosheet structure with an ultrathin carbon layer, significantly enhancing electronic conductivity, reducing ion diffusion pathways, and preserving structural integrity during cycling. The T-Nb2O5@UTC electrode demonstrates an impressive specific capacity of 214.7 mAh g−1 at a current density of 0.1 A g−1, maintaining 117.9 mAh g−1 at 5 A g−1, much outperforming the bare T-Nb2O5 (179.6 mAh g−1 at 0.1 A g−1 and 62.9 mAh g−1 at 5 A g−1). It exhibits outstanding cyclic stability, retaining a capacity of 87.9% after 200 cycles at 0.1 A g−1 and 83.7% after 1000 cycles at 1 A g−1. In a full-cell configuration, the assembled T-Nb2O5@UTC||LiFePO4 battery exhibits a desirable specific capacity of 186.2 mAh g−1 at 0.1 A g−1 and only a 1.5% capacity decay after 120 cycles. This work underscores a nanostructure engineering strategy for enhancing the electrochemical performance of Nb2O5-based anodes toward high-energy-density and fast-charging applications.

In a groundbreaking study, researchers have developed a novel nanocatalyst that promises to revolutionize the field of wastewater treatment, particularly in the degradation of toxic dyes. This research highlights the synthesis and characterization of a catalyst composed of multi-walled carbon nanotubes (MWCNTs) decorated with niobium pentoxide (Nb2O5). The innovative catalytic properties of this material emphasize its potential applications in environmental remediation technologies, particularly for the degradation of azo dyes, a common pollutant in industrial wastewater.

NioCorp (NASDAQ:NB) reported assays from the first completed diamond drill hole (NEC25-024) at the Elk Creek Project in southeast Nebraska on October 16, 2025. The hole returned multiple intervals including 42.00 m @ 1.33% Nb2O5 and other notable intercepts with elevated scandium, titanium oxide and TREO values. The Pentagon funded the drilling program, which supports conversion of resources/reserves and an ongoing review of up to $800 million in potential EXIM Bank debt financing. Remaining assays from the program are pending and additional technical work is required before any reserve/resource reclassification.
