The device developed by TU Bergakademie Freiberg researchers uses aluminum as an anode, graphite as a cathode, and a polymer-based solid electrolyte. It is being validated and further developed for industrial production. The goal is storage capacity of 10 kWh.
Technical university TU Bergakademie Freiberg has reported significant progress in the development of an aluminum battery, which is based on materials that are both readily available and recyclable.
Their battery features aluminum as the anode, graphite as cathode, and a polymer-based electrolyte developed at the university. The first prototype will consist of a “stack” with 10 cells and will be able to store around 1 Wh of electricity.
Validation of the prototype for industrial production will be funded by the Saxony state ministry of economic affairs and the European Regional Development Fund (ERDF), until the end of 2025.
“The aim of the further development is a storage capacity of 10 kWh, which corresponds to the average daily production of a photovoltaic system on the roof of a single-family home,” said Amir Mohammad, research associate at TU Bergakademie Freiberg’s Institute of Experimental Physics.
A 10 kWh capacity would make the aluminum polymer battery suitable for use as a stationary power storage device, especially in private photovoltaic systems.
“The aluminum polymer battery is a promising alternative to lithium-ion batteries which my team has been researching intensively for around 10 years and which is now being tested for industrial production and application,” said Dirk C. Meyer, director of the university’s Institute of Experimental Physics and spokesman for the institution’s Center for Efficient High-Temperature Material Conversion. |
