General Motors announced a new joint venture with SolidEnergy Systems, a spinoff of the Massachusetts Institute of Technology that is focused on improving the energy density in lithium-ion batteries. The two companies plan on building a test facility in Woburn, Massachusetts, for a high-capacity preproduction battery by 2023.
The company is sticking with its estimate of 450 miles of range for now, declining to speculate as to how many more miles it anticipates adding through its battery venture with SolidEnergy Systems.
