Thanks to the boom in renewables, these days the limiting factor of the energy revolution is not power supply as much as power storage. Cleaner, greener batteries are needed to charge our cars, e-bikes, and devices for longer.
A big ongoing issue is that even the best batteries have problems. For example, one big sticking point with lithium-ion cells is that they use lithium as a key component. This is mined as salt. Since Europe does not presently have any large reserves, it relies on imports from only a small number of places, such as Australia and Chile. Other problems with lithium batteries are that they are expensive, have a limited storage capacity, and lose performance after repeated charging.
She and her team of partners have been working on perfecting a recipe for a better solid-state lithium battery. The job involves looking at all sorts of candidate components for the battery and working out which ones work best together. Dr. Mailley says they have now identified suitable components and are working out ways to scale up the manufacturing of the batteries.
The project’s coordinator is chemist Dr. Eduardo Sanchez at CIC energiGUNE, a research center near Bilbao in Spain. He explains that plenty of large-scale redox flow batteries are already in operation around the world and they are designed to be stable, lasting about 20 years. But these existing batteries use vanadium dissolved in sulfuric, which is a toxic and corrosive process. Safety requirements mean these batteries must be manufactured at great expense.Dr.
