The development of innovative and sustainable lithium-ion cells for battery systems of future battery-electric vehicles is the subject of the now-launched European project ‘IntelLiGent’. The project aims to realise these battery technologies on an industrial scale and bring them to market maturity.

InteLiGent bundles the know-how of European partners to enable high-performance and low-cost batteries for battery-electric vehicles of the future, according to a statement by the AIT Austrian Institute of Technology. Challenges such as energy density, service life and fast-charging capability combined with low manufacturing costs are the focus of the various project goals.

Because: “The increasing demand of batteries for electric passenger cars in the EU requires striving for low cost and sustainable battery technologies,” say the researchers.

The key data targeted for innovative and sustainable cells sound quite ambitious. For example, “optimised high-voltage electrodes” should enable high energy densities of more than 350 Wh/kg at high charging currents of more than 2C. A complete charge from 0 to 100 per cent should be possible in less than 30 minutes.

By stabilising the boundary layers, the service life is to be increased to more than 2,000 cycles. “Transfer of sustainable and low-cost manufacturing to industry scale will impact manufacturing costs and environmental impact of future EV batteries,” it continues, adding: “Reduction of critical raw material is achieved by applying cobalt-free cathode material.”

Combining these goals in one cell is likely to be particularly challenging – the end result of the project is apparently to be a multi-layer pouch cell. “The increasing demand for battery electric vehicles poses major challenges for the industry on different levels,” says David Dirnbauer, battery researcher at the AIT Center for Low-Emission Transport. “Within the framework of IntelLiGent, we aim for a significant contribution to sustainable, resource-saving and at the same time cost-efficient battery cell production in Europe.”

Partners in the project include Customcells, E-lyte Innovations, Vianode, SINTEF, Empa, Oxford University and the AIT Austrian Institute of Technology.
