SS-SMARTECH Calendering and Slitting Machine is used in the manufacture of Li-ion battery electrodes. The coated cathode/anode electrode is rolled and evenly pressed to the required thickness by the continuous hydraulic roller device, and then slit into a number of battery electrodes of the required width and wound up neatly. After the battery electrode is coated and dried, the peeling strength between the active substance and the collector foil is very low, so it needs to be rolled to enhance the bonding strength between the active substance and the foil to prevent from peeling off in the process of electrolyte soaking and battery use. At the same time, the roll pressing of the battery electrodes can compress the cell volume, improve the energy density, reduce the porosity between the active substance, conductive agent, and binder inside the electrodes, reduce the resistance of the battery, and improve the battery performance.

SS-SMARTECH High-speed Slot Die Coating System is a high precision pre-metered coating system, by evenly coating the prepared slurry on the substrate with high precision and then winding after dry treatment, to prepare for the later process. It solves the problems of poor accuracy, low efficiency, high energy consumption and coating liquid exposure to the environment of the traditional transfer coating, which is suitable for the cathode and anode coating of lithium-ion batteries, and can also be widely used in papermaking, optical film and other industries.

The Cyclic High-Efficiency Slurry Mixing System (Vorlenmix) streamlines powder/liquid pre-mixing and fine dispersion into a single machine, enabling rapid preparation of high-quality battery slurry. The system first disperses powder agglomerates into a fine, smoke-like state using the crushing head. Utilizing the vacuum generated by the Venturi effect, the powder is swiftly wetted by the centrifugal “liquidfall” and undergoes pre-mixing. The pre-mixed slurry then passes through the narrow gap between the rotor and stator, achieving high shear rate dispersion. With the high-flow circulation mode, the entire batch of materials undergoes multiple dispersions in a short period, resulting in the finished slurry.

This integrated design combines high-efficiency kneading with high-speed dispersion, employing a unique high-viscosity kneading and online dispersion process. This approach significantly enhances the solid content of positive and negative electrode slurry, dramatically reducing production costs of lithium battery and representing a crucial advancement in lithium battery slurry mixing technology.

The main equipment consists of a twin-screw extruder and an online disperser, enabling continuous slurry mixing. The continuous kneading disperser, compared to traditional batch slurry mixing methods, allows for entirely continuous, large-scale slurry mixing with a maximum capacity of up to 3,000-5,000L/h. By combining the advantages of high-viscosity kneading with a screw extruder and the high-shear benefits of an online disperser, this system further improves slurry efficiency, consistency, and reduces one-time investment and operational costs of the line as a whole.

SS-SMARTECH High-speed Double-sided Simultaneous Slot Die Coating System is wide in width of high speed and high precision pre-metered quantity coating system, which can realize the double side simultaneous coating and drying of substrate. It solves the problems of poor drying consistency, high energy consumption and large footprint of traditional coating machine, and is suitable for lithium-ion battery, optical film and other industries.

SS-SMARTECH High-speed Double-sided Simultaneous Micro-gravure Coating System is a new type of coating equipment. With micro-gravure coating technology, it can achieve high speed and high precision double-sided coating function. It solves the problems of poor accuracy, low efficiency, high energy consumption, and exposure of coating liquid to the environment of traditional gravure coating. It is suitable for cathode/anode conductive primer layer coating for for Li-ion battery, ceramic diaphragm coating, etc., and can also be widely used in optical film, functional film, paper printing and other industries.
