  • Today‘s electromobility consumes large amounts of traction batteries, preferably high-performance lithium-ion batteries. These batteries contain valuable raw materials and should not be discarded as waste at the end of their life. Efficient recycling requires closed materials loops and a logistic solution capable of growing along with the increasing number of waste batteries from more and more electric vehicles. The research project »Automotive Battery Recycling 2020« which was launched earlier this year with EU-funding from EIT RawMaterials sets out to identify efficient recycling routines that are ecologically sound, economically viable and readily transferable to industrial scale. The overall aim is to improve the EU-wide recycling chain and add to a secure supply of raw materials through the recovery of valuable materials from waste streams.

  • Whether in use as starter battery in vehicles, as power back-up or for the storage of energy from renewable sources: Lead-acid batteries are among the oldest and most common battery systems in Germany. About 200 000 tons of them come to market each year. And their disposal is excellently organized: in Germany, waste batteries undergo a well-established recycling by manufacturers and processors. But the turnaround in German energy policy is posing new demands on electrochemical energy storage systems. Electric vehicles and stationary storage units for photovoltaic systems, for instance, look for long service lives and high power densities. The battery experts of the Fraunhofer R&D Center Electromobility Bavaria located at the Fraunhofer Institute for Silicate Research ISC now joined forces with a consortium of partners from industry and research to shape up this old system and make it fit for the future.

  • No chance without them: High-performance batteries are the key to electromobility. And the market is growing. Europe expects to see a lot more of electric vehicles by 2030. The EU commission is promoting the development of high-performance batteries accordingly. Among the researchers working to make the vision come true are those of the Fraunhofer Institute for Silicate Research ISC in Würzburg, Germany. They take part in the collaborative project SOLID that was recently launched to develop a simple low-cost method for battery mass production via the sol-gel route. The aim is to provide industry with the much needed large-scale production option for safe high-performance lithium-based solid state batteries.

  • Lithium-ion batteries are subject to a myriad of negative influences during their life span. The mere production process itself and subsequent transport from the production site impose mechanical stress. Whether in power tools, electrically driven forklift trucks, cars or trains – their life will always be full of vibration, sudden impact or shock whenever obstacles have to be crossed, when they are dropped or simply when charging or discharging induces volume changes in their electrodes. In late 2017, the project “ReViSEDBatt“ was launched to investigate the effects of mechanical stresses on the cycle life and safety of lithium-ion batteries. The overall project goal is to optimize batteries so they can better cope with everyday stress.

  • In the SoCUS project, the Fraunhofer R&D Center for Electromobility Bavaria is developing cost-effective sensor systems that can be integrated directly into the battery and can measure the state of charge more accurately than commercially available systems. The systems use ultrasound pulses to measure and evaluate the density of the negative anode which changes with the state of charge of the cell.

  • Cruising range is one of the greatest challenges for the rapid implementation of electromobility in Europe. Ten partners from industry and research organizations now join forces in the EU funded project ECO COM'BAT, coordinated by the Fraunhofer Project Group Materials Recycling and Resource Strategies, part of the Fraunhofer Institute for Silicate Research ISC, to develop the next generation of lithium-ion batteries – the high-voltage battery. Better performance is not the only goal for the new battery. Compared to conventional batteries the new type should be more powerful and with regard to the materials used even more sustainable. The main task here is the substitution of conventional, often expensive, rare or even critical materials.
