NOVEMBER 2024AUTOTECHOUTLOOK.COM9Our experimental capabilities are world-class. For example, we can perform forensics on different cells at the nanoscale using tools such as atomic layer deposition microscopes. This lets us analyze small, subtle changes within the structure of a cell without having to take the cell apart, allowing us to continue experiments without disruption. We are also applying state-of-the-art computational tools that enable us to manipulate the atomic structures of battery anode and cathode materials with computer algorithms that can suggest new nanomaterials that no one has previously thought of.My experimental and modeling teams are closely integrated, and this is part of our secret to success. Everything that my team does is motivated by our end goal: produce batteries that provide great value for our customers while also meeting our vehicle requirements.In addition to studying existing and future battery cell chemistries, we also search for ways to more effectively commercialize them. Within our R&D labs, we can even produce prototype battery cells, albeit at the small rate of less than 10 meters per minute (compared to more than 50 meters It's incredible to think that today's Ultium-powered EVs vehicles such as the GMC HUMMER EV and Cadillac LYRIQ are powered by something so small. While our Ultium propulsion technology can power an entire portfolio of EVs, we're not stopping thereper minute for a commercial cell operation). This fusion of our nanomaterial knowledge and LGES' cell-making capabilities will lead to even better results at our joint venture in the future as we scale this technology. The experience that we gain every day in both our R&D labs and production facilities is supplemented by knowledge we leverage from the external technical community through venture capital investments. Examples of GM Ventures' portfolio companies that specialize in nanomaterials include Mitra Chem, who will help us accelerate the work we're already doing on next-generation, iron-based cathodes for more affordable EVs through their AI-based platform and labs. GM and OneD Battery Sciences also executed a joint research development agreement focusing on the potential application of OneD's SINANODE nanotechnology, which adds more silicon to the anode battery cells by fusing silicon nanowires into EV-grade graphite.The EV space, in general, is still very much an emerging field, and to stay at the forefront of this dynamic space, we every day apply the might of our corporate and leveraged resources to the out-of-the-box thinking needed for future GM EVs. A testament to this is GM R&D's 2,000-plus electrification-related patents. Our inventive capabilities, combined with 116 years of manufacturing know-how and demonstrated experience in scaling technology, give me confidence that we're on the right track.
