As battery production continues to expand across the electric vehicle and energy storage markets, manufacturers are investing in faster, more efficient coating and drying systems. Oxytech Systems infrared dryers are engineered to meet these demands—providing precise, uniform heat transfer that accelerates solvent removal, reduces energy consumption, and ensures consistent electrode quality.
Our infrared drying systems are used by battery manufacturers, electrode coaters, and material developers who need reliable, repeatable drying performance at production scale. With decades of experience designing infrared and ultraviolet curing systems, we offer proven solutions for the most demanding industrial environments.
The Role of Infrared Drying in Battery Manufacturing
In lithium-ion battery production, drying is a critical step in electrode preparation. The process begins with coating a slurry of active materials, binders, and solvents onto thin metal foils—aluminum for the cathode and copper for the anode. After coating, moisture and solvents must be precisely removed to ensure proper adhesion, porosity, and conductivity.
Infrared drying provides a fast, efficient way to remove these solvents without overheating or damaging the metal foil. The radiant energy emitted by Oxytech Systems IR dryers is absorbed directly by the coated layer, leading to rapid surface heating and solvent evaporation. This allows for shorter drying times, higher line speeds, and improved coating uniformity compared to conventional hot-air ovens.
Advantages of Oxytech Systems Infrared Dryers

Infrared dryers deliver heat instantly to the coating, reducing residence time and enabling higher web speeds. Many customers achieve up to 50% faster drying compared to convection-only systems.
- Superior Energy Efficiency
Our targeted infrared technology minimizes wasted energy by focusing heat on the coating—not the surrounding air. This precise energy use lowers power consumption and reduces overall operating costs.
- Uniform Drying and Coating Quality
Even heat distribution ensures consistent drying across the web, reducing binder migration, cracking, and other coating defects that can compromise battery performance.
- Compact, Modular Design
Infrared dryers take up less floor space than traditional drying tunnels and can be integrated into both new and existing roll-to-roll coating lines.
- Advanced Process Control
Each system is equipped with zone-based temperature control, intensity adjustment, and optional closed-loop feedback. Operators can fine-tune drying conditions for different electrode formulations and coating thicknesses.
- Environmentally Responsible Operation
Infrared drying reduces the volume of solvent-laden exhaust air, decreasing the load on solvent recovery systems and helping manufacturers meet environmental compliance and sustainability goals.
Optimized for Electrode Coating Applications
Every battery chemistry has unique coating and drying requirements. Oxytech Systems engineers tailor each system to match the thermal profile, solvent type, and substrate used in your process.
We offer multiple infrared wavelength technologies for maximum flexibility:

Infrared dryers for battery manufacturing: FAQs
What makes infrared dryers effective for battery electrode coatings?
Infrared (IR) dryers transfer heat directly to the coating, accelerating solvent evaporation and reducing dwell time. This targeted heating improves drying uniformity and helps minimize defects like mottling, pinholes, and binder migration.
Are IR dryers suitable for lithium-ion anode and cathode materials?
Yes. IR systems can be tuned for typical lithium-ion chemistries and binders (e.g., PVDF, water-based systems) by adjusting wavelength, intensity, and zone control to match the coating’s absorption profile and line speed.
How do infrared dryers improve production efficiency?
By delivering rapid, uniform heat to the coating, IR dryers shorten drying cycles, enable higher web speeds, and reduce bottlenecks compared to convection-only ovens, often without increasing footprint.
Can IR drying enhance coating quality and consistency?
IR promotes even solvent removal across the web, which helps stabilize adhesion, porosity, and thickness profiles. Better consistency supports downstream calendering and slitting with fewer reworks.
Do IR dryers work for separator films and substrate-sensitive materials?
Yes. With proper wavelength selection and closed-loop temperature control, IR can dry separator films and sensitive substrates while limiting thermal stress and shrinkage.
How are IR dryers integrated into existing coating lines?
IR modules can be deployed as standalone zones or hybridized with convection ovens. Typical integrations include preheat, primary dry, and post-flash zones with recipe-based control tied to web speed.
What controls ensure uniform drying and repeatability?
Multi-zone IR arrays with PID control, pyrometers or embedded thermocouples, and web speed synchronization maintain setpoint accuracy. Recipe management locks in parameters for repeatable runs.
Is IR more energy-efficient than convection-only drying?
IR targets the coating directly, reducing heat loss to air and equipment. This can lower energy consumption per meter dried, especially in high-throughput lines where quick ramp-up is valuable.
How does IR drying impact solvent handling and emissions?
IR accelerates evaporation at the coating surface; exhaust capture and treatment should be matched to your solvent system (e.g., NMP recovery or VOC abatement). Hybrid systems can optimize airflow and recovery performance.
What safety features are recommended for battery manufacturing IR lines?
Typical safeguards include over-temperature interlocks, enclosure shielding, emergency stop circuits, airflow verification, and solvent vapor monitoring aligned with your process safety standards.
How do IR dryers handle different web speeds and coating thicknesses?
Adjustable power density, zoning, and dwell length let IR dryers scale to varying speeds and thicknesses. Recipe-driven control ensures proper evaporation rates without skinning or overheating.
What maintenance is required for IR dryer reliability?
Routine tasks include emitter inspection, cleaning of reflectors and shields, verification of sensors and interlocks, and periodic calibration to maintain uniformity and energy performance.
Can IR systems be customized for specific battery chemistries and substrates?
Yes. IR wavelength selection, emitter type, zoning, and enclosure design are tailored to the absorption profile of your coatings and substrate, ensuring efficient drying with minimal thermal risk.
What measurable outcomes can IR drying support?
Manufacturers commonly target reduced dry time, improved thickness uniformity, fewer defects, stable adhesion, and lower energy per unit output, all tracked via in-line QA and batch reporting.
How do IR dryers complement downstream processes like calendering and slitting?
Uniform drying improves mechanical stability, enabling consistent calendering pressures and cleaner slitting, which can reduce waste and improve electrode roll quality.
