GM builds new research center for e-auto batteries-e-auto

The US manufacturer General Motors has announced to build a new center for the development and marketing of more durable and affordable electric car batteries. The system calls the manufacturer Wallace Battery Cell Innovation Center, it is located on the campus of the GLOL Technical Center of GM in Warren, Michigan, is already under construction and should be completed in mid-2022. The Wallace Center aims for improved cell chemistry, better cell architecture and more efficient manufacturing processes for future cell generations.

According to GM, the system will play a crucial role in further developing the vision of a fully electric future and help pave the way for a broad introduction of electric cars. In this case, GM can build up battery development at GM Research and Development for more than a decade. One goal is to reduce costs compared to current batteries by at least 60 percent in the next generation of its ultium-mentioned battery cells.

In mid 2022, the first construction phase of the Wallace Center should initially open up and already built the first prototype cells at the end of 2022. With increasing demand, the system can also be expanded to do well the threefold of the initially planned construction. “The launch of the Wallace Center will represent a massive expansion of our battery development and will be an important part of our plan to build cells that will be the basis for more affordable, longer-range electric vehicles in the future,” said Doug Parks, GM executive vice president, Global Product Development, Purchasing and Supply Chain.

GM does not want to commit itself to a specific battery technology, but wants to develop and test different battery types and formats. Among other things, the manufacturer wants to work on lithium-metal, silicon and solid-state batteries and their production methods, which can be integrated and produced relatively easily in existing production facilities. The Wallace Center is also said to be able to build large-scale prototypes of in-vehicle lithium-metal battery cells that go beyond the small lithium-metal cells typically used in mobile devices or research applications. According to the manufacturer, these cells could be up to one meter in size, almost twice the size of the current Ultium pouch cells, and are said to be based on a proprietary formula from GM.

The team at the Wallace Center is expected to experiment with many other types of future battery chemistries in addition to the lithium-metal, silicon, and solid-state batteries already mentioned. The manufacturer expects to be able to produce batteries with an energy density of 600 to 1200 watt hours per liter. For comparison: According to Fraunhofer ISI, current lithium-ion batteries have an energy density of around 400 watt hours per liter. GM also wants to use artificial intelligence for the development, with all battery-related processes inside and outside the laboratory connected in a huge cloud.

The facility is named for Bill Wallace, a GM director who played a key role in the development of GM’s battery technology and trained many of the manufacturer’s current battery researchers. As Director of Battery Systems and Electrification, Wallace led the team that designed and brought into production the battery systems in the Chevrolet Volt 1, Volt 2, Malibu Hybrid and Bolt EV. Wallace worked at GM until his untimely death from cancer in 2018. His legacy lives on through both the Wallace Battery Cell Innovation Center and the team he has influenced.
