Slide background


Lithium cell technology at the Fraunhofer Institute for Silicon Technology: Custom Cells Itzehoe GmbH utilises the ISIT’s superior lithium-polymer accumulator technology, which has been undergoing optimisation and enhancement in the “Integrated Energy Systems” department for more than 10 years now. The resulting modular system makes it possible to build solutions for very specialised and demanding requirement profiles. The manufacturing concept is based on a lamination technology and enables CCI to produce customised lithium accumulators offering a broad range of formats and a whole spectrum of unique features. The process begins with electrode foil manufacture using state-of-the-art materials and process control.

The “Integrated Energy Systems” department’s modular system, which is used by CCI, undergoes continuous enhancement and is optimised to the very latest customer requirements over the course of extensive development projects. Small standardised test cells are the basis for rapidly generating a range of parameters that can be reliably scaled into application-specific, large-format lithium accumulators.
