Dürr to supply Cellforce with specialized electrode coating process

The Dürr Group will supply German battery manufacturer Cellforce Group, a joint venture between Porsche and battery company Customcells, with electrode coating for high-performance battery cells. Dürr says its process for coating electrodes is unique, because the two sides are not coated one after the other, but simultaneously. This accelerates the process, increases precision and… Read more »

Pickering Interfaces launches simulator for BMS validation

Signal switching and simulation company Pickering Interfaces has launched a new family of battery simulator modules for EV battery stack emulation in battery management system test applications. The 41-752A (PXI) and 43-752A (PXIe) modules enable direct voltage and current readback either through programming or using Pickering’s soft panel control. Accuracy of each cell simulator is… Read more »

HIU researchers develop high-energy-density lithium metal cell with good stability

Researchers at the Helmholtz Institute Ulm (HIU) have developed a new lithium metal battery that they say offers an extremely high specific energy of 560 watt-hours per kilogram (Wh/kg) based on the total weight of the active materials. The team used a nickel-rich cathode that allows a large amount of energy to be stored, and… Read more »
