Tungsten carbide coating for battery electrode roller

We have accumulated extensive experience in coating applications, and we are currently replicating these successful cases.

Hot-sprayed tungsten carbide coating on rolls

In the rubber-magnetic, magnetic-plastic, and rubber-compounding industries, the wear resistance, service life, and surface quality of rolls used in magnetic-rubber sheet rolling mills are key indicators for assessing the quality and cost-effectiveness of magnetic-rubber sheets, directly impacting both product quality and economic benefits for enterprises.

Tungsten carbide coating for electrode roll strips

The active material, binder, and conductive agent are mixed together to form a slurry, which is then coated onto both sides of a copper or aluminum current collector. After drying, the solvent is removed to form electrode sheets. The particle coating on the electrode sheets is compacted and densified through calendering, and then the sheets are cut or slit into strips.

Offer metal powder coating, wear-resistant metal spraying, and wear-resistant metal coatings.

We can restore scrapped and out-of-tolerance mechanical parts, bringing them “back to life.” Additionally, we can pre-protect the surfaces of new workpieces with wear-resistant and corrosion-proof coatings, effectively “extending their lifespan.”

Wear-resistant coating for electrode roller

Tungsten Carbide Coating for Electrode Rollers: The typical manufacturing process for lithium-ion battery electrodes involves mixing active materials, binders, and conductive agents to form a slurry, which is then coated onto both sides of copper or aluminum current collectors. After drying, the solvent is removed, resulting in electrode sheets. The particle coating on these electrode sheets is subsequently compacted and densified through rolling, followed by cutting or slitting into individual strips. Rolling is the most commonly used compaction technique for lithium-battery electrodes. Compared to other compaction methods, rolling significantly alters the pore structure of the electrode sheets and also affects the distribution of conductive agents, thereby influencing the electrochemical performance of the battery. To achieve an optimized pore structure, it is crucial to have a thorough understanding of the rolling compaction process. Figure 1 illustrates the basic process of electrode rolling. Materials—Equipment—Processes—Solutions: We have accumulated extensive experience in coating applications and are currently replicating these successful cases. We will guide you through the entire coating-manufacturing transition process, ensuring: rapid production start-up; a reliable supply solution covering materials, equipment, and processes all in one package; coating trials conducted either at your site or at our technology center; and consistently high coating quality and efficiency.

1. Roller pressing is the most commonly used compaction process for lithium-battery electrode sheets. Compared to other processing methods, roller pressing significantly alters the pore structure of the electrode sheets and also affects the distribution of conductive additives, thereby impacting the electrochemical performance of the battery. 2. Based on comparative analyses with multiple electrode-sheet rolling machines and in alignment with the needs of battery manufacturers, our company has developed a high-precision, high-strength coating for battery electrode-roll rollers. This coating specifically enables precise control over the shape of the electrode sheets, effectively addressing the issue of uneven thickness—where the center of the sheet becomes thicker while the edges remain thinner—caused by deflection and deformation of the rollers during the rolling process. We have accumulated extensive experience in coating application across materials, equipment, processes, and solutions, and we are now replicating these successful cases. We will guide you through the entire coating-manufacturing transition process, ensuring: rapid production start-up; a reliable supply solution covering all aspects—from materials and equipment to processes; coating trials conducted either at your site or at our technical center; and consistently high coating quality and efficiency.
