US National Lab Unveils Innovative Battery Line for Grid Storage

The United States Department of Energy's Pacific Northwest National Laboratory (PNNL) has inaugurated a cutting-edge battery production facility aimed at advancing energy storage technology. Located in Richland, Washington, the new line is part of the Grid Storage Launchpad (GSL), a 93,000-square-foot research center dedicated to developing safer and more cost-effective batteries for electric grid applications. This marks the first prismatic battery cell production line established at a U.S. national laboratory.

The facility includes state-of-the-art equipment that enables researchers to manufacture, test, and validate advanced battery designs on an industrial scale. Adam Jivelekas, GSL operations manager, highlighted the importance of bridging the gap between scientific research and commercial applications through this initiative. The production line is housed within a specialized dry laboratory where humidity levels are meticulously controlled to prevent degradation of sensitive battery components.

Prismatic batteries, which are rectangular in shape and larger than cylindrical cells, offer several advantages for grid storage. They can store more energy per cell due to their size and design, making them less prone to overheating because of their metal casing that facilitates better heat dissipation. Additionally, the rectangular form allows these batteries to be stacked efficiently, reducing wasted space compared to cylindrical alternatives.

The PNNL team plans to demonstrate the facility's capabilities by producing and evaluating two promising battery chemistries: sodium-ion and lithium-iron-phosphate (LFP). These tests will help validate the scalability of these technologies from coin-cell prototypes to full-scale prismatic cells, paving the way for their commercialization.
