Reducing costs of electric vehicle batteries

Costs of manufacture of batteries and power trains of electric vehicles can be halved by 2018, if the gaps in the innovation chain can be closed. For reaching this objective, Karlsruhe Institute of Technology (KIT) scientists are developing concrete, close-to-industry solutions for energy stores and power trains and combine them on the system level. A close-to-industry ''research factory'' is planned to be constructed on the premises of KIT.

 KIT will present its concept of the 200-million-Euro project in the coming week at the IAA International Motor Show.
 
''It is no longer focused on studying individual molecules or components, but on developing solutions on the system level, which meet industrial requirements,'' explains the project head Andreas Gutsch. Under the ''Competence E'' umbrella project at Karlsruhe Institute of Technology (KIT), 250 scientists from 25 institutes cooperate in an interdisciplinary manner in order to commercialise innovations from research.
 
The list of developments made by KIT is long - Nanomaterials based on iron-carbon already have twice the specific capacity compared to conventional batteries. A new process reduces the filling time of batteries with electrolytes to one tenth. The corresponding patent has been applied for. Modular battery and power train concepts will allow for a massive cost reduction in mass production.

''To make use of the large innovation potential resulting from the high number of partial improvements, we will consistently pursue further development on the system level,'' announces Gutsch. For this purpose, a so-called ''research factory'' is being planned at KIT.

Here, the gap in the chain of innovation and added value between research and industry will be closed by the construction of demonstrators and prototype fabrication lines for novel batteries and electric motors based on KIT's know-how.
 
The project costs for construction and development are calculated to amount to about EUR 200 million until 2018. Similar to other publicly funded big research facilities, such as accelerators and clean-room laboratories, the ''research factory'' will be opened to all partners from industry and research and, thus, contribute to a rapid and wide dissemination of new technologies in Germany.

''It is a central objective of Competence E to rapidly commercialise innovations from Karlsruhe,'' emphasises Gutsch. Apart from teaching and research, innovation is one of the three pillars of KIT. ''We are actively approaching industry and will even intensify these efforts. We are conducting excellent research for application, not for the drawer.''
 
Under the Competence E project of KIT, about 150 new positions are to be occupied by engineers. The first 50 engineers will be employed in 2012 already. In an extra-occupational qualification program at KIT, they will be trained to become specialists in the field of electromobility. Applications for the positions will be invited in Germany and Spain.
 
Karlsruhe Institute of Technology (KIT) is a public corporation according to the legislation of the state of Baden-Württemberg. It fulfills the mission of a university and the mission of a national research center of the Helmholtz Association. KIT focuses on a knowledge triangle that links the tasks of research, teaching, and innovation.
