Extending lithium-ion battery (LIB) equipment with high-performing surface solutions
Lithium-Ion Battery Production Enhancement
Linde Advanced Material Technologies offers surface treatments designed to extend the lifespan of lithium-ion production equipment while maintaining essential surface characteristics. Our solutions help reduce production costs and enhance productivity by preserving product quality and optimizing equipment performance.
Benefits
Built to withstand some of the toughest conditions, our coatings deliver reliable protection and enhanced durability across a wide range of applications. Linde Advanced Material Technologies coatings are engineered for exceptional resistance to:
- Oxidation
- Heat
- Abrasion
- Erosion
- Corrosion
Applying fine, abrasive electrode materials onto foils using gravure or slot-die processes poses challenges such as equipment wear, loss of profile, and inconsistent coating thickness or coverage.
Our Solution:
We deliver advanced wear-resistant ceramic coatings (LC-4) with textured patterns for gravure rolls to preserve the profile and achieve uniform coverage. Additionally, we provide carbide coatings for slot-die lips to retain their precise profile. These solutions offer:
- Enhanced coating quality by maintaining the original profile
- Improved campaign longevity due to increased durability
- Lower spare parts usage through extended equipment life
In producing alumina-coated separator films, maintaining consistent thickness and achieving 100% coverage of the alumina coating is critical. Any deviation may increase the risk of cell shutdown under abnormal heat, inadequate short-circuit prevention, and reduced ion transport.
Our Solution:
We offer wear-resistant ceramic coatings (LC-4) with a textured pattern, applied using the gravure process. This innovative solution ensures alumina thickness and coverage while extending production campaigns. Key benefits include:
- Superior quality by retaining the original coating profile
- Increased production efficiency with fewer roll changeouts
- Reduced inventory costs thanks to extended roll life
When blending fine particle-size electrode materials, excessive wear to the base metals of mixing tanks and elements can contaminate chemistry and compromise product quality.
Our Solution:
We provide durable wear- and corrosion-resistant materials, including ceramics, carbides, fluoropolymers, and weld overlays to address this. Leveraging our proprietary EXOGARD™ process, we apply a highly effective carbide coating that minimizes wear caused by fine electrode materials. Key benefits include:
- Minimized component wear to maintain product integrity
- Reduced machine downtime for sustained productivity
- Consistent, repeatable performance supported by our expertise
- Minimized metal pollution
Surface treatment is vital for achieving high-quality, long-lasting LIB calendering rolls. Over time, rolls can lose their profile and surface finish, resulting in reduced adhesion, irregular thickness, and inconsistent density.
Our Solution:
Our surface treatment solutions are designed to improve roll performance and campaign life. By retaining the original roll profile and surface quality, we ensure top-tier results in:
- Maximized adhesion strength between electrode and foil
- Optimal ionic conductivity for enhanced performance
- Precise thickness and density to meet production targets
- Smooth electrode surfaces with minimized peaks

Recycling Vessels & Tanks Built to Last
As LIB recycling often involves the use of harsh, corrosive chemicals, it’s crucial that equipment is designed to endure these demanding conditions.
Our Solution:
We protect the interiors of vessels and tanks with our proprietary SERMASHIELD™ 1000, engineered to provide exceptional corrosion resistance at temperatures up to 260°C. This proven solution is ideal for applications involving leaching chemicals and hydrogen peroxide, offering a seamless, penetration-free barrier.
EXOGARD™ Coating for Superior Protection
LIB production components require durable, high-performance coatings to resist corrosion and wear over time.
Our Solution:
Our EXOGARD™ coatings are engineered to be dense, ultra-thin, and smooth, offering unmatched protection against corrosion and wear. Applied through our cutting-edge thermal spray coating process, these coatings are REACH-compliant, environmentally friendly, and an excellent alternative to hard chrome.
