Flake vanadium pentoxide (V₂O₅ Flake) is a form of vanadium pentoxide, which is golden or orange-yellow flake crystals with good chemical stability and redox properties. Compared with powder, the flake structure has higher crystallinity and better purity, which is convenient for storage and transportation and use, and is often used in high-end application fields.
Application advantages of vanadium pentoxide flakes
1. Battery materials
Lithium battery/sodium battery positive electrode material:
Vanadium pentoxide has a layered structure, which is conducive to the embedding and release of lithium ions, and can achieve high capacity and high energy density.
Energy storage system: used in liquid flow batteries (such as vanadium batteries) to improve charging and discharging efficiency and cycle life.
2. Catalyst field
Denitrification catalyst (SCR): V₂O₅ is the key active component for selective catalytic reduction (SCR) to remove NOx.
Organic synthesis reaction: such as oxidant in oxidation reaction, used for propylene oxidation to prepare acrolein, benzene oxidation to prepare benzoquinone, etc.
3. Ceramic and glass industry
Colorants and decolorants: give special colors to glass or ceramics (such as blue, green, and yellow).
Fluents: improve the thermal stability and mechanical strength of glass.
4. Infrared and optical materials
Infrared absorption materials: used for optical applications such as infrared protection and infrared filters.
Thermochromic and photochromic materials: used for smart windows, sensors, etc.
5. Magnetic and electronic ceramics
Used in soft magnetic materials and varistors to improve their electrical and magnetic properties.
