Although there is a rapidly growing market for rechargeable batteries, the essential raw materials are limited. Sodium-ion batteries, for example, could be a substitute. A collaborative research team from Helmholtz-Zentrum Berlin (HZB) and Humboldt-Universität zu Berlin has explored new groupings of electrode materials and electrolyte solutions for this purpose.
With operando techniques, it is possible to observe how solvated ions embed themselves in batterie electrodes. This might help to develop alternative batteries. Image Credit: © G. A. Ferrero
In contrast to lithium-ion batteries, which are based on the storage of lithium ions in the positive and negative electrodes of the battery, we are working on the one hand with sodium ions, as they also occur in cheap table salt. On the other hand, we store the sodium ions together with their…
