GM announced today that it is building a new battery plant in Michigan to develop lithium metal and solid state battery cells.
The new facility will be called the Wallace Battery Cell Innovation Center in honor of Bill Wallace, who led the team that designed and released GM’s advanced automotive battery systems in the Chevrolet Volt 1, Volt 2, Malibu Hybrid and Bolt EV before dying of cancer in 2018..
It will be located at GM’s Global Technical Center in Warren, Michigan:
Today, General Motors announced the Wallace Battery Cell Innovation Center, a brand new facility that will significantly expand the company’s battery technology operations and accelerate the development and commercialization of longer-range and longer electric vehicle batteries. affordable. The Wallace Center will be located on the campus of GM’s Global Technical Center in Warren, Michigan.
GM said the team will develop next-generation battery cells.
It will include “lithium metal and the solid state”:
The Wallace Center-based battery engineering team will be experimenting with many types of future battery chemistries in addition to lithium metal, including pure silicon and solid state, as well as different cell form factors. The Wallace Center is expected to build batteries that range in energy density from 600 to 1,200 watt hours per liter, along with essential ingredients for battery cells such as active cell materials.
However, the new plant will not produce large volumes of battery cells and will focus on prototypes:
The Wallace Center will be able to build prototypes of large format lithium-metal battery cells for use in vehicles beyond the small-scale lithium-metal cells typically used in portable devices or research applications. These cells could measure up to 1,000mm, nearly twice the size of the original Ultium pocket cells and will be based on GM’s proprietary formula.
But the new battery plant team will work to help roll out production of the new battery cells at GM and LG’s Ultium battery plants.
