Abstract: ‘Fresh Air’ for a sustainable Energy Future – Metal Air Batteries Rüdiger-A. Eichel Chair for Energy Conversion & Storage RWTH Aachen University Director Institute of Energy & Climate Research IEK-9: Fundamental Electrochemistry Forschungszentrum Juelich D-52425 Jülich, Germany Abstract Electrochemical Energy Storage systems are being thought as the solution for the vast demand for high power (ultra-capacitors) and high energy (batteries) density. Such systems hold a great promise, while pressure on researchers grows as the need for more energy in mobile devices (from small hand held electronic to large mobile systems as electric vehicles) and static energy storage for grid applications, dramatically increase with evolving technology. Metal-air batteries offer high energy density due to their unique structure as most of the battery volume consists of the anode (fuel), while the air at the cathode (and more specifically oxygen), is being consumed from the atmosphere via a thin air cathode membrane. Metal-air technologies (Zn and Al air batteries) are already commercialized, and by using Li and Si as fuels even more advanced metal-air batteries may be formed. The introduction of a new class of electrolytes, based on room temperature ionic liquids (RTIL’s) may enable the establishment and commercialization of these advanced metal air batteries for electric vehicles (EV).
