The main objective of the project is the development of a bimodal lithium-air cell that is to work in a normal environment (air). Significant challenges are the microstructure of the oxygen electrode, a bi-functional multi-component catalyst system that allows both reactions in discharge (ORR) and charge (OER) processes. In addition, there is a new electrolyte system. An innovative design concept of the cell is realised and demonstrated by a functional pattern. In order to ensure the sustainability of the developed lithium-air battery, an eco-design and assessment of environmental effects of the battery materials are carried out as well.
