Introduction to the current situation of lithium battery industry

With the vigorous development of the new energy industry, screw pumps are used in several key nodes in the current lithium battery process technology, and the current industry applications are highly dependent on imported brand products.
As a company specializing in the development and production of screw pumps, Standard has developed several specifications of screw pumps that can adapt well to the current industry applications, and the stability of the products is comparable to that of imported brand products, and has the advantages of faster delivery and better service.


For lithium-ion battery manufacturing, we currently have three series of products suitable for:
(1). Lithium battery slurry conveying screw pump
(2). Lithium battery coating screw pump
(3). Lithium battery edge coating screw valve

Process considerations

(1). Slurry conveying process: realize the slurry transfer with stable flow
The material can be conveyed stably and without shearing using the progressive cavity pump, and the conveying efficiency can be easily set by adjusting the speed of the progressive cavity pump.

(2). Coating process: Achieve high-precision supply electrode material and homogenize the thickness of the coating film.
Using a progressive cavity pump allows the electrode material to pulsate-free and quantitatively supply to the coating die, this results in uniform coating on the diaphragm material. The conveying of the medium is not affected by viscosity, and even high-concentration slurries can be supplied without pulsation. The output flow can be easily adjusted over a wide range by simply controlling the rotation speed of the progressive cavity pump, helping to homogenize the thickness of the film layer in the precision film coating process.

(3). Edge coating process: realize a small amount of high-precision supply electrode material and uniformize the thickness of the coating film
The use of micro screw valves and micro coating dies can evenly coat the electrode material on the diaphragm material without pulsation. Suitable for coating electrode materials with narrow slits at the edge of the film. The conveying of the medium is not affected by viscosity, and even high-concentration slurries can be supplied without pulsation. The output flow rate can be precisely adjusted by controlling the rotation speed of the screw valve, helping to homogenize the thickness of the film layer in the precision film coating process. Through the return suction performance of the screw valve, it can achieve precise start and stop, uniform material cutting without residue, and intermittent coating can be realized and material can be saved.

(4). Vacuum degassing process: realize strong suction in high vacuum environment.
Through the attraction generated by the stator and rotor of the screw pump, even in a high vacuum environment, it can be strongly sucked in high-viscosity liquids or high-concentration slurries for quantitative transportation.

(5). Dispersion process: improve the uniformity of slurry.
Through the dispersion equipment, the liquid material is supplied quantitatively without pulsation, and the dispersion effect of microparticles is improved. Depending on the ability of the decentralized equipment, it is also easy to adjust the flow rate

Case study

High-precision supply of electrode materials and uniform coating film thickness
Even with high-concentration slurry, constant supply without pulsation is possible regardless of viscosity. Contributes to uniform film thickness in precision thin film coating. The amount of discharge can be easily adjusted over a wide range by simply controlling the rotation speed.

Powerful suction even under high vacuum conditions
Due to the suction force generated by the rotor/stator, high-viscosity liquids and high-concentration slurries can be strongly sucked and transferred in fixed amounts even under high-vacuum conditions.


Improve slurry uniformity
Liquid material is supplied to the disperser without pulsation, and the dispersion effect of fine particles is enhanced. It is easy to adjust the flow rate according to the capacity of the disperser.
