Scientists have created a battery from vanillin

Researchers have developed a technology for the manufacture of a redox electrolyte for running batteries from vanillin.

Usually vanillin is used asaromatic substance. However, a team from the Graz University of Technology was able to create a liquid electrolyte from it, which is now mainly made from environmentally harmful heavy metals or rare earth elements.

To obtain the aromatic compound, the scientists recycled lignin from waste paper production, usingThese are "gentle" chemical processes without the use of toxic substances and expensive catalysts.All operations are highly scalable, suitable for continuous production, and canIt is carried out at room temperature, so the team is already discussing cooperation with pulp mills.

Using the vanillin obtained in this way, the researchers created a prototype of a 3 kWh flow battery and experimentally confirmed its efficiency, long life, safety, and recyclability.According to the developers, the device can be used to store large amounts of energy fromwind and solar power plants or as backup storage for hospitals, mobile communication systems, gas stations.

Previously, we also reported on the development of a battery made from radioactive nanodiamonds with a service life of more than 90 years.
