Lithium Battery Slurry Preparation Solutions

PD Slurry Preparation System

Built around the dual planetary mixer (PD mixer), the system combines planetary revolution, blade rotation and high-speed dispersion to uniformly mix high-viscosity slurry without dead zones. It is suitable for batch production of lithium battery cathode and anode slurries. The system covers a full range from laboratory scale (1L) to industrial production (3400L). Planetary motion of the mixing blades and dispersion discs provides thorough shear and kneading, ensuring slurry uniformity and batch-to-batch consistency.

High-Efficiency Inline Slurry Preparation System

Developed as an upgrade to the PD mixer slurry preparation system, this solution uses separate kneading and dilution-dispersion processes. It enables precise formulation and process control and efficient mixing of all components, ensuring high-quality finished slurry and significantly improving battery performance and cycle life. A preferred solution for high-solids slurry preparation in the battery industry.

High-Speed Circulation Slurry Preparation System

Developed in-house using patented technology, the system employs a unique dispersion module to rapidly and thoroughly mix powders and solvents. Its independent recirculating dispersion system efficiently homogenizes slurry, ensuring stability and consistency. A simple drive structure delivers high torque while significantly reducing failures, improving homogenization efficiency and equipment utilization.

Twin-Screw Continuous Slurry Preparation System

Developed in-house by Hongyun Machinery, the modular twin-screw continuous slurry preparation system integrates automatic batching, continuous conveying, efficient kneading and dispersion, and continuous slurry preparation. It offers low power consumption, high efficiency, a compact footprint and easy maintenance. The production process is fully automated and adaptable to a wide capacity range, meeting lithium battery slurry production needs from 30 to 3000 L/h.

Solid-State Batteries

System Solutions for Dry and Wet Electrode Preparation for Solid-State Batteries

Complete Dry Electrode Equipment Solution

Dry electrode technology supports cathode systems including lithium (manganese) iron phosphate, ternary materials, lithium cobalt oxide and lithium manganese oxide, as well as anode systems including graphite, silicon-based materials, hard carbon and soft carbon.

Complete Wet Electrode Equipment Solution

Suitable for wet mixing of all-solid-state battery materials and premixing for electrolyte films, this solution advances mixing toward thorough dispersion. The wet-process dual planetary mixer handles high-viscosity slurries and supports both wet and dry mixing process routes.
