Heater rollers in battery manufacturing

Modern heater rollers in battery manufacturing

In battery production, heater rollers are mainly used in the processing of electrode materials, in drying, calendering, laminating and coating processes. There, a uniform temperature across the entire web width determines the material properties and therefore the quality of the battery cells. Even small temperature fluctuations can affect the performance and service life of the cells.

Heating systems based on liquid media generate heat outside the roller and supply it via reservoirs and piping. They respond slowly, take up space in the machine and cause heat losses. Electrically heated rollers, by contrast, generate heat directly inside the roller. They respond faster to temperature changes, can reduce the energy demand of the heating system and are easier to integrate into the machine.

For these applications, INOMETA supplies the electrically heated INOheat^® heater roller. It operates without thermal oil, has a compact design, offers precise temperature control and is designed for operating temperatures of up to 200 °C. As a functional roller within complex process lines, it is tailored to the specific production requirements and complements the portfolio of rollers for battery manufacturing.

Efficient battery production with precise temperature control

Efficient battery production with precise temperature controlIn modern manufacturing of batteries, especially in lithium-ion battery production, heater rollers are indispensable components — precise temperature control, a space-saving design, and homogeneous heat distribution are essential for efficient production processes.
A key difference between conventional heater rollers and INOheat^® heater roller lies in the innovative machine concept. While conventional heater rollers work with external medium storage, piping, and pump systems, the INOheat^® heater roller eliminates the need for these additional components. This not only reduces the required installation space but also lowers installation effort, significantly simplifies maintenance, and avoids heat transfer losses that can occur when the heating medium is transported through piping systems.
Another advantage is the flexible control system. Our heater rollers can be operated either decentrally via a control unit or seamlessly integrated into the machine control system. This not only saves space but also reduces installation costs, significantly simplifies maintenance, and eliminates the energy loss associated with transporting heated media through pipes to the process.

Heater rollers are used in various battery cell production processes, especially in areas where precise temperature control and surface treatment are required. The most important areas of application include:

• Stretching processes – controlling the temperature for targeted material deformation.
• Battery cell production – optimization of electrode production through precise drying and calendering.
• Fuel cell production – ensuring the quality and performance of cell materials.
• Calendering – ensuring uniform temperature distribution for compaction of electrodes.
• Lamination processes – supporting the layering and coating of materials for durable electrodes.

Heater rollers by INOMETA for highest quality standards in battery manufacturing

The INOheat^® heater rollers from INOMETA set new standards in industrial heat transfer. By using high-quality materials such as steel and aluminium, they offer an optimal combination of thermal conductivity and mechanical stability.
While conventional systems rely on liquid heating media and therefore exhibit thermal inertia, direct energy input into the roller can reduce heat transfer losses and lower the energy demand of the heating system.
With a maximum operating temperature of up to 200°C, INOheat^® ensures uniform and precise temperature distribution over the entire roller surface. This precise temperature control is essential for processes where even slight temperature fluctuations can affect product quality.
The individual surface adaptation is also impressive: depending on the application, hard metal coatings for high wear resistance, non-stick coatings to reduce material adhesion, and elastic covers with varying degrees of hardness (e.g., FKM) are available.

The most important advantages of the INOheat^® heater roller for your battery production

Thanks to customized production, INOheat^® heater rollers are not limited to standard dimensions — they are individually designed to your requirements and equipped with fixed journals for maximum stability and durability.

Especially relevant for your battery production: the INOheat^® heater roller generates process heat directly and locally in the roller, with no reservoirs, pipes or pumps required. This means for you: very good energy efficiency, extremely low service effort, and shorter heating and preheating times in cell manufacturing.
