In e-mobility dosing applications, the focus is on fast and uncomplicated processing of materials, combined with defined cost control. Applications of materials with the highest viscosities and abrasive properties are particularly challenging. The specific characteristics of the materials must be maintained, unaffected by the dosing process. Even with a high filler content.
Our dosing systems based on the endless piston principle offer excellent conditions for processing all low to high viscosity 1-component and 2-component materials, e.g. gap fillers and liquid seals or in potting and bonding applications.We have summarized some application examples for you:
Production of battery cells in E-Mobility
For safety and functional reasons, it is imperative to ensure bubble-free dosing when filling the batteries in e-mobility production. ViscoTec dosing systems guarantee a filling of the material without air admission. The repeatability of our systems is >99 %. Low material loss due to an optimized emptying system ensures optimized processes.
In addition, a highly precise and reproducible application of the slurry is one of the key processes in battery production. ViscoTec offers many advantages:
- Easy integration in existing machines or productions.
- Accurate application of the slurry onto the separator fleece.
- Continuous dosing process with the endless piston principle.
- Processing of low up to high viscoity materials (up to 7,000,000 mPas).
The metal-free dispenser enables dosing and dispensing of high-reactive materials like:
- Ionic liquids
- Anaerobic adhesives
- Sulfur and chlorine-based electrolytes
- Sulphuric acid
Battery module & Battery pack production in e-mobility
The dosing technology from ViscoTec is known for a safe, long life, cost efficient and flexible technology for sealing applications since decades.
Sealing applications at the housing of the battery management systems and on the battery packs are state of the art. ViscoTec products are used in 1-component and 2-component applications. They convince by flexible use of the easy controllability. In addition, the avoidance or reduction of welding processes prevents heat from entering the battery cells.
An optimized thermal management is very important for a permanent use of the battery systems. This includes a heat removal of the electronic componets of the management systems and also a heat removal of the cells and packs or modules aswell. ViscoTec dosing systems are perfectly suited for the high-precision application of 1- and 2-component thermal pastes as well as filled and abrasive materials. This results in long service lives with hardly any wear.
Potting or bonding applications are used in the production of the battery packs as well in the electrical contacting systems. This applies to both 1- and 2-component. For safe material handling during the process, without dripping.
To increase the service life, battery management systems are encapsulated in e-mobility. This serves as protection against external influences (e.g. moisture, dirt, vibration, etc.). And the improvement of their own properties (e.g. heat dissipation). We can handle 1- and 2-component materials. Important: No air is introduced into the material during dosing.
To protect the coils of the rotor and stator of the electric machine the coils will be potted, respectively impregnated with low viscosity compounds.
- Safe material handling during the process, no dripping material
- No air is introduced into the material during dispensing
In order to withstand high loads, magnets are bonded in the production of electric motors.
- Dosing without influencing the fillers (e.g. hollow glass spheres)
- Cost and quality control through reproducible dosages
- Dosing in horizontal and vertical positions
To improve the service life, electronic components such as electronic housings, connector housings and FFC’s (Flat-Flex-Cable) are potted. This serves as protection against external influences (e.g. moisture, dirt, vibration, etc.). And the improvement of their own properties (e.g. heat dissipation). We can handle 1- and 2-component materials. Important: No air is introduced into the material during dosing.
Volumetric metering technology has already proven itself in recent decades as a safe, reliable, cost-effective and flexible sealing technology.
Adhesive and sealing applications are also state-of-the-art in the housing seals of battery management systems and battery packs or battery modules for e-mobility.
- Flexible use of easy controllability
- No heat input into battery cells due to avoidance of welding processes
