AI Technical Summary
Existing technologies make it difficult to effectively synthesize titanium-based phosphate materials using industrially pure raw materials. Impurities affect battery performance, resulting in high costs and difficulty in industrial production.
A solid-state reaction high-temperature sintering method was adopted, using sodium hydroxide or ammonia water and reagents such as barium carbonate, barium chloride, and calcium chloride to treat industrial-grade raw materials. The particle size was reduced by air jet milling and wet grinding, combined with spray drying and inert atmosphere sintering, to prepare structurally stable titanium-based phosphate active materials.
It lowers the purity requirements for raw materials, improves the purity of material synthesis, enhances battery performance, reduces manufacturing costs, and is suitable for industrial production.
