Established production processes


The manufacturing processes for solid-state batteries with liquid electrolytes have been tested in many ways and are fully developed. The chemistry of our solid state electrolyte allows the new solid state electrolyte conductor to be manufactured within the battery cell and utilises the production processes for batteries with liquid electrolytes. No new production technologies need to be developed and trialled. This reduces the implementation risks “from laboratory to production” compared to other solid-state battery projects and makes our technology an attractive investment.

Renowned partners


Production will be modular, with three 400 MWh production modules to be built in the first expansion stage in order to achieve the target capacity of 1.2 gigawatt hours. The high level of standardisation of the factory structure will facilitate economies of scale and rapid implementation, meaning that the total capacity of 7.6 gigawatt hours will be reached in just a few years.


Swiss Clean Battery is relying on established and renowned partners to build the factory and equip it with the necessary production facilities. For example, Jonas & Redmann (Berlin), Munters (Hamburg), Dalex (Wissen) and Metha Bau (Amriswil) are on board.

Well known location


The factory is to be built in Domat-Ems directly on the A13 motorway, where the canton of Graubünden has promised a plot of land. In terms of an accelerator approach, the start of production with a 100 MWh plant with around 50 employees and 625,000 batteries per year is a promising option. In the subsequent expansion stage with 1.2 gigawatt hours per year, around 7.5 million batteries will be produced. In the future, the factory is expected to deliver 7.6 gigawatt hours per year with 47.5 million batteries. By this time, around 800 jobs will have been created on seven floors. There are already concrete plans to acquire corresponding licences for other European countries and to develop sites – for example in Germany, Austria, or Spain.



The installation of home or industrial storage systems requires careful planning. Objectives, storage requirements and dimensioning of the storage system are important factors in planning. We take a holistic approach to this. Which PV systems exist or should be added, which load peaks define the design, should charging stations be installed or does it make sense to market the free storage spaces – possibly together with other users? We use these components to develop a sustainable and cost-efficient storage system in order to offer users an optimised solution.
