Batteries

Today, Li-ion batteries provide the highest energy density of all existing systems.However, most car manufacturers agree that the Li-ion technology is still not satisfactory for long distance EV use (TNO Automotive, HTAS). Higher energy density, reduced costs and improved safety are needed (NXP, Philips). This also concerns rechargeables for medical applications (NXP, Philips). We will carry out research to (I) develop new generations Li-ion batteries delivering roughly twice the energy density and to satisfy the safety requirements of today’s systems, and (II) step in new or relatively unexplored directions if we are to significantly increasing energy storage beyond Li-ion, like, e.g. solid-state, Lithium-sulfur, or Lithium-air batteries. These post Li-ion cells offer higher energy storage than Li-ion, but none is a technology at the present time, and hence, are worthy of further study in order to establish their capabilities. Without such studies it will be impossible to determine which, if any, could become a viable commercial technology. 

Hence, our interdisciplinary research is characterized by four important features, fundamental science (NXP), modelling (NXP, Philips), materials development and fabrication (Euro Support, Tata Steel, Norit, Süd-Chemie, Roth&Rau, Tempress, Oxford Instruments, Sabic), and system testing and evaluation (Comibol, IMEC, HTAS).
