Stuttgart – The Alpha-Laion project to develop high-energy traction batteries for electric vehicles has begun with a kick-off meeting. The project lead partner is Robert Bosch GmbH, with BASF SE, Wacker Chemie AG, SGL Group, Daimler AG, and BMW AG as additional partners.

Electromobility is central to making eco-friendly, sustainable mobility possible. This is the basis of the National Platform for Electric Mobility, which brings important industrial and academic partners together with the vision to make Germany the leading supplier and market for electromobility by 2020. Establishing technology leadership in the area of electrochemical cells and batteries as well as integrated manufacturing in Germany are key to achieving this.

The electrical properties of batteries are still a major hurdle, which both the industrial and scientific communities are working hard to surmount. In terms of market acceptance, electric vehicles' range and the cost of their energy storage devices are the two factors that will have the greatest impact, and improvements in these areas will help electromobility achieve a breakthrough.

Formed in 2012, the Alpha-Laion joint project is working on these aspects. The goal is to develop lithium-ion cells with an especially high energy density, and which use innovative materials for cathodes, anodes, separators, and electrolytes that are stable at high voltages. The combination of these new elements will enable a completely new electrochemical system for use in lithium-ion cells. Only by combining the right materials with the appropriate cell design, and by adapting process technology to the new materials will it be possible to maximize lithium-ion cells' storage capacity and long-term durability.

The joint project is one of the National Platform for Electric Mobility's lighthouse projects, and over three years will receive 13 million euros in funding from the Federal Ministry of Economics and Technology (BMWi). In addition, the consortium partners are contributing a total of 19.5 million euros of their own capital.

The goal of their joint efforts is to achieve lithium-ion cells with an energy density of more than 250 watt-hours per kilogram. This would allow the range of compact electric vehicles to be significantly extended to 250-300 kilometers. The benefit to customers from this is clear – they would be able to drive considerably longer without recharging, and they would be less restricted by the availability of charge spots.
