Spray Pyrolysis Equipment for Ternary Lithium Battery Materials

Technical Principle: Spray pyrolysis (SP) is a continuous and efficient powder production process. A precursor solution is atomized into fine droplets and passed through a high-temperature reactor, where drying, thermal decomposition, and sintering take place to produce high-purity powders with uniform particle sizes...

Product introduction

Key Features and Advantages

1. Uniform Composition and Excellent Doping Performance

Uniformly mixed precursor solutions promote consistent elemental distribution, making the process suitable for composite oxides, high-entropy materials, and doped materials.

2. Controllable Particle Morphology

Adjustable process parameters enable the production of spherical, hollow, porous, and core-shell particles with good flowability and packing properties.

3. Short Production Cycle

Atomization, drying, thermal decomposition, and crystallization are integrated into a streamlined process, reducing the need for prolonged milling and repeated high-temperature treatment.

4. Continuous, Scalable Production

Continuous feeding and digital process control support efficient production and easier scale-up for industrial applications.

5. High-Purity and Versatile Material Production

By selecting suitable precursor solutions and controlling the reaction atmosphere, the equipment can produce various functional powders, including oxides, metal alloys, and sulfides. It can also support functional thin-film coating applications.

6. Controlled Particle Size Distribution

Adjustable nozzle specifications and gas flow rates help control droplet size, enabling the production of micron- and submicron-scale powders with relatively narrow particle size distributions.
