Battery Process: Lab Mixing Machine

Laboratory battery slurry mixer

In the entire lithium battery research and development, mixing battery slurry is the first step in the production of lithium-ion batteries. The quality of its slurry dispersion effect directly affects the quality of subsequent lithium battery production and the performance of the battery.

As an expert in battery production equipment manufacturing, Xiaowei has developed a slurry mixer equipment that does not contain copper, zinc and other elements specifically for the material properties of lithium metal. After inspection, it meets the requirements of lithium battery production process.
At the same time, during the production process of lithium battery slurry mixer, we also strictly control the production environment, operating process, temperature, humidity and dust, eliminating the hidden dangers of related substances entering it, and ensuring quality and safety.

Laboratory lithium battery slurry mixer features

1. Good sealing performance, eliminating air leakage and oil leakage;
2. The rotor and bearings are made of high-strength carbon steel and bearing steel;
3. High linear speed;
4. Large torque output;
5. Can be customized according to customer needs.

Suggestions for purchasing lithium battery slurry mixer:

1. Capacity:

The manufacture of batteries requires more pole pieces and requires better consistency of the battery cells. This requires the mixer to have a certain capacity.
At present, Xiaowei’s battery slurry mixer can reach a capacity of 500ml – 10L (lab type), which meets your test requirements.

2. Have a good vacuum sealing system:

The mixer needs a good vacuum sealing system to prevent the emission of irritating organic gases and degas the battery slurry.

Xiaowei’s mixer vacuum degree is no-load for 24 hours and maintains pressure above -98Kpa, ensuring that there is no oil leakage or gas leakage during the mixing process.

3. The material has corrosion resistance, wear resistance and stable physical and chemical properties:

The strong alkalinity of the positive electrode material and the strong corrosiveness of NMP require the mixer to have excellent corrosion resistance.

We use all imported angular contact ball bearings, and the stirring paddle is made of stainless steel 316L precision casting, which has strong corrosion resistance, wear resistance and stable physical and chemical properties.

4. The mixing paddle has a reasonable structure and the mixing speed design meets the requirements:

In addition to sufficient mixing power and mixing range, the shape and mechanical design of the mixing blades have a great influence on the slurry preparation.

Our battery slurry mixer uses precision cast twisted paddles, which can adapt to different processes (dry mixing, wet mixing).
