Bosch and partners launch project to develop 250 Wh/kg EV batteries

Robert Bosch GmbH and other partners BASF, Wacker Chemie AG, SGL Group, Daimler AG and BMW AG have launched a joint project named Alpha Laion to develop high-energy traction batteries for electric vehicles

Electromobility is an important key to a low carbon and sustainable change mobility. This is the core of the National Platform for Electric Mobility, which is composed of the most important industrial and academic partners in Germany and follows the vision of making Germany in 2020 to lead provider and leading market for electric mobility.

Establishing technological leadership in the field of electrochemical cells and batteries and an integrated production in Germany, are of central importance. Yet, the electrical properties of the battery the most basic challenges, to which both the industry and the academic environment with high motivation to work. Thus the range of electric vehicles and the cost of energy storage are the most important market-dominating figures of helping to electric mobility breakthrough.

Established in 2012, launched joint project Alpha Laion is exactly effective at these points. The objective is the development of lithium-ion cells with particularly high energy density based on innovative materials for cathodes, anodes, separators and high-voltage stable electrolytes.

The combination of these components allows new future a whole new electrochemical system for use in a lithium-ion cell. Only with the right combination of materials, the appropriate cell design and adapted to the new materials, process technology, the storage properties of the new lithium-ion cell used optimally and high long-term stability can be achieved.

This joint project is one of the flagship projects of the National Platform for Electric Mobility and is over three years funded with 13 million euros from the Federal Ministry of Economics and Technology (BMWi).

The consortium partners provide equity in the amount of approximately EUR 19.5 million. goal of the joint activities is lithium-ion cells to achieve with an energy density of about 250 Wh / kg. Thus, the range of compact electric cars are significantly increased to 250 to 300 kilometers. The benefit for the customer is obvious - it is much longer mobile and independent of recharging stations.
