24M Technologies unveils Electrode-to-Pack technology

24M has unveiled its Electrode-to-Pack System (ETOP™), which integrates the electrodes directly into the battery pack, eliminating the need for separate cells and modules. According to 24M, the ETOP™ achieves pack efficiencies of more than 70 percent, one of the highest available pack-level volume efficiencies. In addition to the optimized process and reduced material consumption, the unit electrodes can be connected in series, parallel, or in combination. This makes it possible to create configurations that are no longer limited by the voltage and capacity of individual cells. Cell manufacturers, automotive OEMs, and ESS integrators produce battery packs and modules from single cells. However, battery packs contain a significant amount of inactive materials, such as supporting metals and plastics, in the cell housing. The 24M ETOP™ technology eliminates other cell materials within the battery pack. This enables manufacturers to achieve the highest energy density at the pack level while reducing costs.

BMW builds battery test center in Wackersdorf

The BMW Group plans to invest around 100 million euros in a battery test center in Wackersdorf by 2026. This center will be integrated into the existing building structures on site. The first areas of the center will begin regular operations as early as mid-2024. Covering an area of over 8,000 square meters, high-voltage batteries, and other electric drive components for future BMW Group models will be tested at an early stage of development. The main investments are focused on setting up the test bench technology and the necessary conversion work on the existing building infrastructure of Hall 80 on the plant site. Shell construction work is currently underway, including a new floor slab for the building. The first section of the center is scheduled to go into operation in mid-2024. In the first step, it will be possible to test hundreds of battery cells simultaneously. After the ramp-up, the test capacities will be expanded to several thousand battery cells. In the final expansion stage starting in 2025, it will also be possible to carry out vibration and shock tests.
