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 between Ems-Chemie and Hamilton in Domat-Ems, directly on the A13 motorway, as the canton of Graubünden has offered a plot of land there. Around 7.5 million batteries will be produced in the first expansion phase with an annual output of 1.2 gigawatt hours. Later, production is set to increase to 7.6 gigawatt hours per year with 47.5 million batteries. The factory with seven floors and around 800 jobs in the final expansion stage is expected to cost between 450 and 500 million Swiss francs.



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.
