4 Degussa s LION Power Concept LION Power combines the Li-ion battery material activities of Degussa with all core competencies in the field of inorganic particles as well as Fine-Chemicals LION Power Increased Safety & Performance Intern. Start-up SEPARION Advanced Separator increased safety and performance commercially available JV Degussa-ENAX* Anodes commercially available Cathodes commercially available higher safety * Closing pending Product-Pipeline Anode materials more capacity Cathode materials improved safety Electrolytes low flammability Core Competencies of Degussa

5 Degussa s Market Approach to the Lithium-Ion Battery Industry SEPARION Separators

7 The Problem: Nail Penetration Test Often Failed in Cells with PO Separators video Temperature [ C] Temp1- top side Temp2-bottom side Penetration depth U cell Penetration depth [mm], Cell voltage [V] Time [sec] 0 Monitored test data and pictures of the cell during and after the test; Weight loss: 56.1%

8 The Solution: SEPARION Separators Improve Nail Penetration Tolerance Temp1- top side Temp2-bottom side Penetration depth U cell video Temperature [ C] Penetration depth [mm], Cell voltage [V] Time [sec] Test data monitored during the test and picture of the cell during and after the test; Weight loss: 0.4%

9 SEPARION Benefits for Li Ion Batteries SEPARION Product Features flexible continuous ceramic with a ultra thin non woven made of oxides of alumina, zirconia and silica SEPARION Benefits for the Battery demonstrates an excellent temperature stability shows a superior chemical resistance stabilizes active materials has an exceptional wettability especially at low temperatures SEPARION Benefits for the End User helps to improve battery safety increases rate capability helps to improve calendar and cycle lifetime

12 Summary: Threats and Opportunities Degussa would like to become a reliable supplier for Li battery materials. New jobs will be established in Germany. However, some regulations are a threat for our strategy, e.g. transportation regulations for Lithium Batteries: Transportation regulations are based on old technology New improved materials can improve safety Transport Regulations have to be adapted to current state of the art, new standards and test methods have to be defined.
