The Ceramic Micro-gravure Roller for Lithium Battery is a specialized precision tool engineered for lithium battery manufacturing, focusing on lithium battery coating and separator coating applications. With its advanced ceramic coating, precision engraving, and robust construction, this roller delivers accurate coating amounts, fast delivery speeds, and consistent performance—critical for meeting the high standards of lithium battery production. Designed to optimize the coating process, it ensures uniform material distribution, enhanced battery performance, and long-term operational reliability, making it an indispensable component for lithium battery manufacturers worldwide.
Achieving flawless execution in energy storage manufacturing requires components that go beyond basic functionality. The Lithium-Battery Ceramic Micro-gravure Roller is engineered to deliver compounding advantages that directly elevate your production capabilities, reduce overhead, and protect your profit margins.
Unyielding Environmental Resistance: The specialized pure chromium oxide surface effortlessly repels the aggressive chemical nature of slurries and functional coatings, preventing premature degradation, oxidation, and pitting.
Unmatched Transfer Consistency: With exceptionally smooth cell walls and flat cell bottoms, the roller guarantees that every drop of expensive coating material is transferred to the substrate, virtually eliminating material waste and uneven spots.
Accelerated Line Speeds: The flawless dynamic balance and ultra-low runout tolerance allow your machinery to operate at maximum velocity without introducing microscopic vibrations that cause chatter marks or coating defects.
Extended Operational Lifespan: The microscopic density of the imported ceramic powder creates an exterior that drastically extends the time between required maintenance cycles, keeping your lines running longer and more efficiently.
Rapid Turnaround Cleaning: The ultra-low porosity ensures that sticky slurries cannot penetrate the surface deeply, allowing maintenance crews to wipe the cylinder clean swiftly and safely during crucial shift changeovers.
Key Benefits
Featuring a special pure chromium oxide (Cr₂O₃) surface layer and nickel-chromium alloy underlayer, the Ceramic Micro-gravure Roller offers outstanding wear resistance, corrosion resistance, and high-temperature resistance. It withstands the harsh conditions of lithium battery coating (including exposure to electrolytes and high processing temperatures) and maintains structural integrity, reducing replacement frequency and operational downtime.
Equipped with ALE fiber laser engraving, the roller ensures precise mesh dimensions and uniform ink (coating material) transfer. It delivers accurate coating amounts—essential for lithium battery performance—while enabling fast delivery speeds that keep up with high-volume production lines. The smooth mesh walls and flat mesh bottom prevent material waste and ensure consistent coating thickness across the substrate.
The use of imported ceramic powder with smaller particles enhances the roller’s durability, extending its service life and reducing maintenance and replacement costs. Its robust design minimizes operational disruptions, allowing manufacturers to optimize production efficiency and lower long-term operational expenses.
The roller’s optimized mesh structure and smooth ceramic surface reduce material adhesion, making cleaning quick and efficient. This simplifies maintenance routines, shortens downtime, and ensures consistent performance over extended production runs—critical for meeting tight manufacturing deadlines.

The Ceramic Micro-gravure Roller is crafted using ALE fiber laser engraving technology, which enables ultra-precise mesh hole creation. This process ensures consistent hole shape, size, and arrangement, critical for accurate coating material transfer. The laser engraving supports fine mesh densities (up to 2000 L/in), allowing for precise control over coating thickness and uniformity—essential for optimizing lithium battery performance.
To achieve the highest quality ceramic layer, the roller undergoes a strict plasma spraying process. This technique ensures the ceramic layer’s porosity (1～2%), thickness, and uniformity are precisely controlled, enhancing its ability to hold and transfer coating materials. The plasma-sprayed ceramic layer bonds tightly to the nickel-chromium alloy underlayer, delivering exceptional bonding strength (40—60 Mpa) and resistance to wear, corrosion, and high temperatures.
Lithium Battery Coating: Ideal for coating electrode materials (cathode and anode) onto current collectors, ensuring uniform material distribution that enhances battery energy density, cycle life, and safety.
Separator Coating: Suitable for coating functional layers onto lithium battery separators, improving thermal stability, electrolyte wettability, and mechanical strength—critical for battery performance and safety.
The Ceramic Micro-gravure Roller for Lithium Battery is compatible with most lithium battery coating machines, adapting to different production speeds and coating materials (slurries, functional coatings). It is designed to meet the strict requirements of lithium battery manufacturing, making it suitable for both laboratory-scale R&D and large-scale mass production.
Understanding the architectural mastery behind the Lithium-Battery Ceramic Micro-gravure Roller reveals why it stands as a critical asset for advanced manufacturing facilities. Each dimension of its design has been optimized to solve specific production bottlenecks.
The foundation of this cylinder's longevity lies in its advanced metallurgical and ceramic bonding. Utilizing imported pure chromium oxide (Cr₂O₃) for the surface and a premium nickel-chromium alloy for the underlayer, the rigorous plasma spraying process achieves a phenomenal coating hardness of HV1400. This impenetrable barrier perfectly withstands harsh electrolytes and extreme thermal processing environments, guaranteeing long-term structural integrity.
Precision dictates performance. By harnessing state-of-the-art ALE fiber laser engraving technology, this cylinder supports ultra-fine mesh densities up to 2000 L/in. The resulting micro-cavities feature glass-smooth walls and perfectly flat bottoms, ensuring the precise transfer of slurries. This exact volumetric control translates directly into highly uniform coating thicknesses, ultimately maximizing the energy density and cycle life of the final energy storage units.
High-speed production demands absolute mechanical perfection. With machining precision that borders on the microscopic, the runout tolerance is strictly confined to a mere 0.005 to 0.01 mm, alongside a cylindricity of 0.01 mm and an 8g dynamic balance quality grade. These exacting standards guarantee whisper-quiet, vibration-free rotation on massive industrial lines, completely eradicating material waste and microscopic coating flaws.
Versatility meets specialization. Tailor-made for the intricate processes of cathode/anode material application and separator functional layer coating, this cylinder integrates seamlessly with the vast majority of mainstream coating machinery. From rigorous laboratory research and development trials to continuous, round-the-clock industrial mass production, it adapts flawlessly to your operational scale.
Operational efficiency is defined by uptime. The astonishingly low porosity of 1 to 2 percent, combined with a formidable bonding strength of 40 to 60 Mpa and a glass-like ceramic finish, drastically reduces slurry adhesion. This intelligent surface engineering not only makes daily cleaning incredibly fast and efficient but also significantly extends the component's service life, driving down your comprehensive operational costs.
