Sulfide-based all-solid-state batteries offer high energy density and high output, making them ideal for large-scale applications, including automotive use. To optimize their performance, the cathode active material in these batteries is coated with materials such as LiNbO3. This coating reduces resistivity and extends the service life of the batteries, ensuring superior efficiency and durability.
Traditionally, LiNbO3 is not soluble in water, requiring the use of ethoxide dissolved in organic solvents for coating applications. However, these organic solvent-based LiNbO3 coatings are highly flammable and necessitate specialized facilities for safe handling. DOWA has achieved a breakthrough by stabilizing LiNbO3 in aqueous solvents. Our water-based coating solution eliminates the need for special facilities, significantly reducing process costs compared to organic solvent-based alternatives. The DOWA coating material ensures low-resistance and highly durable batteries. It forms a dense coating on positive electrode active materials and allows for the formation of LiNbO3 at lower temperatures than organic solvent-based coatings. We offer customizable compositions of our materials to meet your specific requirements.
Our cutting-edge coating material is designed for use in sulfide-based all-solid-state batteries. Featuring surface modification and a specialized coating on the positive electrode active material, this innovation enhances battery performance and longevity.
