Project Sense is researching next generation batteries

The European battery research project Sense is looking for next-generation lithium-ion batteries. They should show significant improvements in energy density, cell chemistry and battery management.

The Sense project is part of the "European Battery Alliance" initiative and the EU research funding program Horizon 2020. The eleven partners, including the Swedish company Northvolt, are researching lithium-ion batteries of "Generation 3b". These are said to have a higher energy density, improved cell chemistry and optimized battery management. Anodes made of silicon-graphite composites should contribute to this, as well as new additives in the electrolyte fluid. Protective layers are also said to age the battery more slowly and enable more charging cycles, and new sensors to improve thermal management.

The sustainability of the new battery generation is also considered in the research project. In this way, the cathode acts without the use of flammable and toxic solvents. Furthermore, the further use of aged vehicle batteries as stationary storage (Second Life) and the recycling of the batteries are seriously looked at in the research activities. The Sense research project is coordinated by the Swiss Federal Laboratories for Materials Testing and Research (Empa) and will end in spring 2024.
