through research


The existing performance capacity of mobile end devices, drones, electric vehicles or within the framework of stationary storage of renewable energies would not exist today without correspondingly powerful lithium-ion batteries. The range of lithium-ion batteries is divided into different cell types depending on the application. Depending on the application area of the cell, various components and material combinations are used.

The numerous combination possibilities result in many possibilities for the optimization and adaptation of lithium-ion cells - also with regard to their specific application. The development of post-lithium systems also offers enormous optimization potential. The investigation of new bonding systems for electrode production, the generation of higher SI components of the anode to increase capacity or the investigation of magnesium-sulfur cell chemistry are just a few examples of the potential development opportunities in the lithium-ion battery segment.

In order to remain at the forefront of technological development, CUSTOMCELLS®, together with numerous interdisciplinary partners from research and industry, is continuously involved in public cooperation projects to research new materials and concepts and to develop new innovations for special applications.

Current research projects

For CUSTOMCELLS® innovation means sustainability.
In this way, business relevant topics can be identified at an early stage, shaped and served.


The aim of the joint project is to demonstrate the performance of a new reversible energy storage technology based on magnesium and sulphur in an industry-compatible battery cell. This project follows on from the developments of the MagS project (2016-2018).


The aim of this cooperation project is the development and implementation of high-capacity anodes for Li-Ion cells. This is to be achieved by using composites of a novel active material, Si-Nanowires (Si-NW) and graphite, as anode active material. The work will be carried out together with the material specialist ENWIRES ».


In this project rechargeable Li-Ion cells are developed, which are suitable for an extended temperature range.


The aim of the project is to explore innovative solutions along the value chain of lithium-ion technology and to validate them in demonstrators.
At the end of the project a competitive production unit with a production capacity of about 6 GWh p.a. will be developed. In the future, this unit can be built modularly and in many ways where the corresponding capacity is needed. Eleven work packages, each led by one of the partners and worked on in teams, will focus on topics such as energy-autonomous infrastructure, cell design, innovative production processes and materials, industry 4.0 or recycling strategies. The project is funded by the Federal Ministry of Education and Research under the number 03XP0142. This will create the basis for the establishment of large-scale production of Li-ion cells in Europe.


In the project ECOLOGICAL COMPOSITES FOR HIGH-PERFORMANCE LITHIUM-ION BATTERIES - April 2016-December 2018 the aim of the project EIT Raw Materials Project ECO COMB'BAT was to combine and scale the combination of the most ecological and high-performance materials possible for the next generation of high voltage Li-Ion batteries.


The KomVar funding project is aimed at setting up series production of high-quality lithium-ion battery cells in small to medium volumes at the CSTOMCELLS® site in Tübingen. The BMWi-funded project was officially approved on 01.09.2019 and, with a total volume of 8.2 million euros (4.7 million euros in funding) over a period of 24 months, is accelerating the development of a "competitive variant production for lithium accumulators with a service character for lithium-ion cell development and for the production of small and medium-sized series for niche markets.
