A new partnership could help General Motors produce electric vehicles with far more range than what’s possible with current technology.

According to the Detroit Free Press, lithium metal battery tech that GM is developing with Singapore-based SolidEnergy Systems could allow future vehicles to travel 500 to 600 miles on a single charge — at a price point that makes them accessible to more buyers.

Big news for GM EV range and costs

This technology, which GM refers to as “Li-Metal,” allows for much greater energy density. That means vehicles that use it could either achieve a much longer driving range without increasing in weight, or keep their current range while getting lighter and more affordable.

“Affordability and range are two major barriers to mass EV adoption,” said GM President Mark Reuss. “With this next-generation Ultium chemistry, we believe we’re on the cusp of a once-in-a-generation improvement in energy density and cost. There’s even more room to improve in both categories, and we intend to innovate even faster than any other company in this space.”

GM’s new Li-Metal tech partnership would represent a major advanced beyond the first generation of Ultium-powered vehicles, which will start hitting the market later this year. These EVs will offer estimated driving ranges that could reach 350 or 400 miles. Cadillac and GMC models on this platform are already planned. Reuss said new Chevrolet EVs could be announced soon as well.

GM began investing in SolidEnergy’s technologies six years ago. Now the two companies are connected even more closely via a joint development agreement. They’ll start by building a new manufacturing prototyping line in Massachusetts. Its goal: turning out a high-capacity, pre-production battery by 2023.

The last year has already seen a flurry of new EV investments from GM. With this latest announcement, the automaker appears poised to make even more significant EV production strides in the coming decade.
