Team develops organic redox polymer for aluminum-ion batteries with improved storage capacity

Aluminum-ion batteries are seen as a promising alternative to conventional batteries that use scarce and difficult-to-recycle raw materials such as lithium. This is because aluminum is one of the most common elements in the Earth's crust, is easier to recycle and is also safer and less expensive than lithium. However, the development of such aluminum-ion batteries is still in its infancy, as suitable electrode materials that provide sufficient storage capacity are still lacking.
