Energy storage systems are already used in many instances today: in batteries for the electric car, in fuel cells, for energy stores in private and commercial buildings (e.g. in connection with photovoltaic units), as well as in electronic products for end users (e.g. battery-operated vacuum cleaner, battery-operated drill). The need for energy-storage systems is increasing in all these areas. IST METZ sees itself not only as a supplier of UV systems for manufacturers of battery systems and for equipment manufacturers, but also as a development partner. Our laboratory and our applications technology department are happy to assist with developing new processes and UV solutions.
