To manufacture prismatic and cylindrical battery cells, OEMs and battery manufacturers need a reliable partner like STIWA. We support our customers from the initial idea through product and process development to highly automated, production of millions of units – from automotive, smart mobility, energy storage, to industrial applications.
With our expertise, we ensure
efficient solutions that guarantee the highest quality and reliable results.
There are no standard solutions for the development and production of battery cell housings. Therefore, it is crucial to have a flexible partner with the expertise and competence to cover the entire process, from development to production.
An optimized cell housing design – minimizing space and complexity – plays a key role in boosting battery performance and achieving maximum energy density.
The battery housing is the central safety component that must meet the highest standards in terms of sealing, electrical conductivity, mechanical strength, and much more. It essentially consists of a battery lid / cap and a battery can – including the critical interface between these two components. High production volumes require manufacturing systems that are both flexible and highly automated to ensure constant quality and efficiency in production.
Maximum efficiency with minimum overall costs
With STIWA, you get more than just innovative solutions – you get long-term economic value. Thanks to our Total Cost of Ownership (TCO) approach, you benefit from sustainable savings. Our products and services are designed for durability and efficiency – delivering the lowest TCO through:
Requirements for battery cell housings
The requirements for battery cell housings are various and include the highest standards in terms of tightness, power transmission, mechanical stability and safety. In addition, they must be produced flexibly and efficiently in large quantities to meet the increasing market needs.
Battery cell housings must meet a wide range of demanding requirements – including the highest standards for sealing, electrical conductivity, mechanical stability, and safety. At the same time, they must be produced flexibly and in alrge quantities to meet the inreasing market demands.
From Lab- to Gigascale
The development of battery cell housings requires the fulfillment of numerous, sometimes contradictory, functional, safety and manufacturing-specific requirements. This is a demanding task that requires a partner who competently accompanies and supports the entire process from the initial idea to the final serial production.
