 The market for Li-Ion Batteries is strongly increasing
 Strong demand for automotive, stationary storage as well as for power tool applications
 New Factories are required in the neighborhood of the end markets
 Within the funded project GigaLIB, M+W developed, together with the project partners VARTA,
Manz, TK Engineering and ZSW a smart size Battery Factory Concept
 6-8 GWh/a capacity is an economic size for such a Factory
 Safety aspects are considered
 Advanced logistic concept
Summary
Smart Size Battery Cell Factory
We are committed to developing a reliable, long-term partnership with our clients
