Niobium Oxide Anodes for Fast-Charging Lithium-Ion Batteries
This community develops niobium-based oxide materials, primarily for use as anodes in lithium-ion batteries, with a specific focus on enabling high-rate charging and energy storage.
The research centers on the synthesis and structural engineering of niobium pentoxide (Nb2O5) and related titanoniobate compounds, such as TiNb2O7. Key methods include pulsed laser ablation for thin-film deposition, chemical synthesis of nanoparticles, and the manipulation of Wadsley-Roth crystallographic shear structures. The work investigates how oxygen vacancies, doping with elements like titanium or tungsten, and carbon composites influence ion diffusion and electrochemical performance. While a portion of the literature addresses photocatalytic applications, the dominant thread is the optimization of these oxides for high-power, fast-charging battery electrodes.
Niobium is the central element, with 1,468 papers representing 2.1% of all tracked niobium research. Lithium contributes 794 papers, accounting for 0.4% of lithium research, and carbon adds 350 papers.
The community comprises 3,455 papers, with the highest publication volume in Catalysis Today, the Journal of Solid State Chemistry, and Zeitschrift für anorganische und allgemeine Chemie.
Recent work continues to explore crystal engineering for fast-charging anodes, the development of dual-phase titanoniobate composites, and the use of niobium oxides in electrochemical sensing and oxygen evolution reactions.
