One of the key challenges of the energy transition is the rising demand for lithium. In the future, there will be a supply gap, even taking into account recycling and the development of new mining areas. In addition to the limited availability, safety risks such as fire hazards make lithium-ion batteries less suitable for the long-term requirements of the energy transition.
Here, we present the aluminium-polymer battery as a novel technology adressing these issues. Aluminium is the most abundant metal in the Earth’s crust and therefore inexpensive. It is available in Europe and is highly recyclable. The battery cells are free of toxic or critical raw materials and eliminate the risk of fire.
Pouch cells consisting of a simple 3-layer setup have been developed: aluminium anode, polymer electrolyte (consisting of AlCl3, Et3NHCl and PAN) and graphite cathode. Capacity, safety and recycling tests show promising results. Remaining challenges are tackling the self-discharge and scaling up the cell fabrication. The future goal is making large-scale storage systems cost-effective, efficient and safe.
