SERIES PRODUCTION

CUSTOMCELLS® TÜBINGEN (CCT) - ONE OF THE MOST MODERN BATTERY CELL SERIES PRODUCTION FACILITIES IN EUROPE IS BEING BUILT HERE

CUSTOMCELLS® is one of the world's leading companies in the development of special lithium-ion battery cells. With the new company location in Tübingen, CUSTOMCELLS® is now expanding its service portfolio and, in addition to consulting, electrode production and prototype development, is now concentrating on the establishment of series production of high-quality lithium-ion battery cells in small to medium volumes as part of the KomVar funding project at the Tübingen company location. The partners CUSTOMCELLS® Itzehoe GmbH, CUSTOMCELLS® Tübingen GmbH, P3 automotive and the Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (ZSW), together with the associated partners Daimler AG, Manz AG and ANDREAS STIHL AG & Co. KG officially launched the KomVar project "Competitive Variant Production for Lithium Accumulators" funded by the German Federal Ministry of Economics and Energy (BMWi). The overall project is being promoted by the partners and the BMWi with a financial volume of 8.2 million euros.

KOMVAR - OFFICIAL PROJECT START

The official project start have ben announced by a 
KomVar opening event on 18 October 2019
at the company's location in Tübingen.

Keyfacts

Revolutionary cell design

CUSTOMER SPECIFIC BATTERY CELL PRODUCTION IN GERMANY

Lithium-ion batteries are a key technology for many areas of industry. Numerous energy-autonomous products are already differentiated today by the quality of the energy storage device, whereby the predominant performance advantage is due to the lithium-ion battery cell used. In addition to large-volume consumer products and increasingly important applications in electric vehicles, lithium-ion battery cells are increasingly being used by niche markets that are dependent on rapid development and adaptation cycles for their products - on the possibility of having cells developed and produced even in small quantities according to specific specifications and performance parameters.

The project represents an important next step for the establishment of a German and European battery cell industry by taking up research and development results from basic projects and bringing them closer to an entrepreneurial application. By focusing on small and medium-sized production volumes, it ideally links up with existing projects to establish large-scale production of lithium-ion battery cells in Germany and Europe. In addition, know-how will be generated and jobs created.

THE FUNDING PROJECT KOMVAR PROMOTES LITHIUM-ION CELL PRODUCTION AT THE TÜBINGEN SITE

In order to solve this situation, it is necessary, in addition to large-scale production of cells in Germany and the EU, to have companies that can offer competitive, variable cell production for the production of small series and for the production of development series. Over a period of two years, the KomVar project will focus on the development and demonstration of such variant production. The project comprises the development and construction of a demonstrator cell production facility. The plants should be able to produce different cell designs and cell technologies in high quality in small and medium quantities. In cell production runs, different cell types will be produced in small series of up to 1,000 pieces during the project period and their quality will be tested. Data on throughput, changeover times and consumption are recorded in these test runs. These data flow into a superordinate economic efficiency concept, which as a result of the project should confirm the general feasibility of the concept by means of a targeted cell price determined in advance.

The project represents an important building block for the German and European industry to catch up in the field of lithium-ion cell development and production by building up further capacities, knowledge and jobs in this area and paving the way for new cell developments, which can then lead to cell production capacities.

KOMVAR - PRESENTATION AND COOPERATION OF THE PROJECT CONSORTIUM

A KomVar consortium will be formed to achieve this goal, which will contribute existing knowledge in the field of cell development to the project and expand this knowledge through corresponding research work. As an associated partner, Manz AG has in-depth plant knowledge and contributes an existing production plant at the company's site in Tübingen to the KomVar project as a research and development platform. This production platform will cover all steps from electrode separation to packaging the cell body in the pouch.

As part of the project-related implementation (electrolyte filling, pre-aging and degassing of the cells), Manz AG will be subcontracted by CUSTOMCELLS® Itzehoe GmbH. In this way, the entire process chain can be mapped and the representability of the KomVar approach can be guaranteed and demonstrated, especially with regard to technical feasibility and competitiveness. Manz will continue to build the KomVar systems according to the development specifications of CUSTOMCELLS® Itzehoe, which are based on the company's own experience of the market situation and on the existing insights and known customer requirements of P3 automotive in the market.

After the development of the concept and the construction and reconstruction of the plants in Tübingen, the newly founded CUSTOMCELLS® Tübingen GmbH will carry out corresponding test runs on the plants using materials from CUSTOMCELLS® Itzehoe. The test runs are accompanied by the ZSW in order to derive and evaluate corresponding quality concepts under these special new conditions. The cells resulting from the test runs are examined and characterized by both ZSW and CUSTOMCELLS® Itzehoe in order to compare them with the previous cost, quality and flexibility standards of CUSTOMCELLS® and other manufacturers. Parallel to the test runs, practical information about the costs of changing formats and cell chemistries will be generated, which will flow into the development of a holistic economic efficiency concept, which will be developed by CUSTOMCELLS® and P3 automotive. After successful completion of the KomVar project, further cooperation with the associated partners Daimler, Manz and Stihl with CUSTOMCELLS® will be sought.
