Sustainable Batteries
The extensive use of batteries for the storage of electric power from wind or solar farms, calls for new types that are more efficient, cheaper and more environmentally friendly. Scientists at the UG work on these new batteries, but also on recycling the ones that have been discarded.
Rechargeable lithium batteries are vital for the green energy transition, but how environmentally friendly are they? UG researchers examine their life cycle, from raw material extraction to end-of-life disposal, and investigate how recycling can be made more effective and greener.
How do batteries work, and can they be improved?
Batteries can convert electricity into chemical power, which can then be released to supply electric power. These batteries are in your phone, a torch, or in your car, as an accumulator is a battery too. The extensive use of batteries for the storage of electric power from wind or solar farms, calls for new types that are more efficient, cheaper and more environmentally friendly.
A lot of research is needed to develop the best or cleanest batteries. For example, the method with which the lithium in your phone battery, electric bike, or car is obtained is not very environmentally friendly. That is why researchers at the FSE are working on alternatives, in which lithium is replaced by sodium for example, which is much easier to extract. They are also looking for alternatives to rare materials, mainly to avoid being dependent on the few countries in the world where they are mined.
Creating sustainable batteries to power the energy transition
An €800 million programme funded by the Dutch National Growth Fund aims to stimulate the Dutch battery ecosystem and make a global impact. Moniek Tromp, Professor of Materials Chemistry, is the ‘front woman’ of this programme and designs and builds the batteries of the future.
It includes the development of new batteries produced through sustainable processes, using materials that are abundant and can be sourced locally. The focus is primarily on batteries that are important for the Dutch economy, such as batteries for heavy-duty vehicles, and large-scale stationary storage. In different programme lines, the consortium will also work on battery re-use and recycling.
A battery’s life: From the cradle to the grave
Rechargeable lithium batteries power equipment, vehicles, and store energy generated by wind or solar power for later use. These batteries are vital for the green energy transition, but how environmentally friendly are they?
