In the joint project ‘BALU - Production technology for battery cell concepts based on aluminium-ion technology’, a consortium of research institutions and specialised industrial companies is further developing the aluminium-graphite dual-ion battery (AGDIB). Due to its high power density, AGDIB technology has great potential in the area of highly dynamic load requirements and could be an alternative to cost- and material-intensive lithium batteries. The project is pursuing the ambitious goal of transferring the production of AGDIB cells from laboratory scale to industry-compatible production conditions. In addition to the transfer of the new battery technology, ecological considerations, such as the avoidance of critical raw materials, environmentally friendly production or subsequent recycling, play an explicit role. The BALU project is funded by the Federal Ministry of Education and Research (BMBF) as part of the ‘Batterie2020Transfer’ programme.
