The project is dedicated to reducing production costs in the manufacturing of cell casings for pouch and prism cells. Already existing production methods are being upgraded.






The greatest challenge in electric mobility is the development of high quality and yet safe energy storage in the form of lithium ion batteries at an acceptable price. In order to fulfil this requirement, a drastic improvement of the production technology used is necessary. Above all, the reject rate in cell assembly must be reduced and plant productivity  increased at the same time.

Goals and approach

The aim of the project OptiFeLio is to optimise the cost intensive production processes. In the planned research topics relating to casing manufacture for lithium ion cells, the three criteria of quality, security and costs are at odds with each other and must be reconciled. The procedure of the second promotion phase of the leading edge cluster electric mobility South West targets both prismatic and pouch cells.

Innovations and prospects

On the one hand, this target is to be achieved through the ongoing development of the existing production processes, such as deep drawing aluminium compound foil into half shell housing for pouch cells. On the other hand, a simplification of the manufacturing process through new product designs, with the integration of additional functions at cell level, is aimed for at the same time. The planned innovations will contribute to strengthening trust in lithium ion technology and to establishing Germany as a leading provider of electric mobility.
