4. Applications
Anode Materials for Lithium-Ion Batteries
Nano MnO offers a high theoretical capacity of ~680 mAh/g making it a highly promising anode material. In practice it is often compounded with carbon materials (e.g. porous carbon graphene) to mitigate volume expansion and high contact resistance during charge discharge thereby delivering higher specific capacity and improved cycle life.
Electrode Materials for Supercapacitors
Its high specific surface area enables high specific capacitance and excellent rate performance making it suitable for high-performance energy storage devices.
Other Battery Applications
Serves as a precursor for synthesizing lithium manganese oxide cathode materials (e.g. LiMn₂O₄).
Shows good potential for use in aqueous zinc-ion batteries (manganese-based oxides).
Can be used for composite modification of cathode materials in lithium-sulfur batteries.
Catalysis
The high specific surface area enhances activity and selectivity making it effective in catalytic reactions such as organic oxidation reduction CO oxidation and denitrification (DeNOx).
Packaging
Available in 100 g to 10 kg options with double-sealed moisture-proof liners. Custom sizes and inert gas purging are available upon request.
5. Frequently Asked Questions (FAQ)
Q1: How should Nano MnO powder be stored?
A1: It should be stored in a sealed container under an inert atmosphere (e.g. argon or nitrogen) in a cool dry place. Avoid exposure to air and moisture to prevent oxidation.
Q2: What is the recommended method for dispersing Nano MnO in slurries?
A2: Ultrasonication combined with mild stirring in suitable solvents (e.g. NMP or ethanol) is recommended. Surfactants may be used to improve dispersion uniformity.
Q3: Is this product suitable for industrial-scale production or only for R&D?
A3: Our Nano MnO is produced with consistent quality and is suitable for both R&D and pilot-scale industrial production. Custom packaging and quantities are available upon request.
Q4: Can this product be directly used as a lithium-ion anode material?
A4: While it can be used directly we strongly recommend compositing it with conductive carbon materials (e.g. graphene carbon nanotubes) to enhance electronic conductivity and buffer volume changes during cycling for optimal performance.
Q5: What is the typical moisture content and tap density?
A5: Typical moisture content is <0.5% and tap density varies by batch. Please contact us for detailed batch-specific analysis reports (COA).
