Applications in the Electric Vehicle (EV) Field
In the EV sector, CY-Mg30D is used as an additive in battery materials to significantly improve energy density, cycle life, and stability. By finely controlling the particle size and distribution of CY-Mg30D, the microstructure of the lithium battery can be optimized. Specific benefits include:
- Nano-structured Cathode Materials: Nano-magnesium oxide (CY-Mg30D) acts as a conductive dopant. Through solid-phase reactions with materials like Lithium Iron Manganese Phosphate (LMFP), it creates magnesium-doped nano-structured cathodes. These materials exhibit high conductivity and an actual discharge capacity of up to 240 mAh/g, characterized by high energy density, stability, and low cost—ideal for liquid/colloidal lithium-ion batteries and high-power batteries.
- Capacity Retention: The addition of CY-Mg30D mitigates capacity decay during cycling, ensuring the battery maintains performance even after numerous charge-discharge cycles.
- Acid Scavenging in Electrolytes: Used as a deacidifying agent in electrolytes, it can reduce free acid content to below 20 ppm. This lessens the dissolution of cathode materials by hydrofluoric acid (HF), thereby enhancing capacity, cycling performance, and overall stability.
- Anode Optimization: In high-capacity tin-composite anodes, adding CY-Mg30D particles (0.05–10 microns) improves specific capacity and first-cycle efficiency while maintaining stable cycling.
- Reduction of Polarization: In systems like Zinc-Nickel batteries, incorporating nano-MgO into the zinc negative electrode reduces polarization during charge-discharge, lowers internal resistance in later stages, and extends cycle life.
Applications in Energy Storage Technology
CY-Mg30D also shows immense potential in energy storage. As a key material for large capacitors and lithium-ion batteries, it enhances storage efficiency and maintains stability under high temperatures:
- Enhanced Surface Area and Conductivity: High-purity CY-Mg30D improves the specific surface area and conductivity of cathode materials, boosting charge-discharge performance.
- Thermal Safety: Its excellent thermal stability and chemical inertness make it an ideal electrolyte additive or coating material, significantly reducing the risk of thermal runaway.
- Lattice Stabilization: In lithium cobalt oxide (LCO) batteries, nano-MgO helps stabilize the crystal lattice and protects the cathode from acid erosion, improving capacity and longevity.
Messi Biology utilizes the ethanol-based hydrothermal synthesis method to produce high-purity, ultra-dispersed nano-magnesium oxide (CY-Mg30D). With available particle sizes of 10nm, 30nm, 50nm, 100nm, etc., their products have shown outstanding results in industries including new energy, semiconductors, chips, optical lenses, membrane materials, polishing, and solar photovoltaics. These high-quality materials effectively replace imported alternatives and serve a wide range of industrial applications.
