Niobium Oxide Anodes for Fast-Charging Lithium-Ion Batteries
This research community develops niobium-based oxide materials to serve as anodes in lithium-ion batteries, specifically targeting high-rate charging capabilities and structural stability.
The work centers on synthesizing niobium pentoxide (Nb2O5) and related titanoniobate compounds, often as thin films or nanocomposites, to improve ion diffusion and reduce volume expansion during charge cycles. Recurring methods include tuning oxygen vacancies, doping with titanium or tungsten, and combining these oxides with graphene or carbon structures. The primary application is the creation of negative electrodes that support fast charging and high power density, with a significant portion of the literature dedicated to understanding the Wadsley-Roth crystallographic shear structures that facilitate this performance.
Niobium research accounts for the largest share of this community's output, comprising 2.0% of all tracked niobium research and 1,427 papers within this group. Lithium research contributes 774 papers, representing 0.3% of its total tracked literature.
The community comprises 3,284 papers, publishing most frequently in Catalysis Today, Journal of Solid State Chemistry, and Zeitschrift für anorganische und allgemeine Chemie.
Recent work continues to focus on crystal engineering and defect management in niobium oxides to enhance low-temperature performance and ultrafast lithium storage, with specific attention to lattice prestressing and interface-driven electrochemical behavior.
