On the 27th and 28th of May, the ALION consortium had its final meeting in Brussels. After four entire years of project execution, the ALION project demonstrated the high power and high cycling performance of the Aluminium-ion battery technology and enabled the emergence of a new serious candidate to substitute Pb-acid batteries in Uninterrupted Power Supply (UPS) and telecommunication applications for stationary applications. 3D printed battery packs were manufactured with nominal voltages of 6, 12, 48 and 72 V, while the cells were connected in series via corner tabs. These packs were the largest ever developed with Aluminium-ion cells. A big step forward for this promising technology! The Aluminium-ion battery shows various advantages compared to current commercial products: it does not contain any critical raw material and it is highly safe as it is water-based and made with non-inflammable materials.
