With one charge from Hamburg to Vienna: General Motors promises super batteries for e-cars

General Motor wants to develop rechargeable batteries with a significantly higher energy density than today's batteries. This should allow an electric car to travel almost 1000 kilometers.


General Motor wants to develop rechargeable batteries with a significantly higher energy density than today's batteries.

Detroit - It's like looking for the Philosopher's Stone.

Electric cars * need batteries that are very powerful with little weight and volume, have a high power output and can be recharged quickly.

It also plays a role that they are protected from damage in the event of an accident.

And of course the batteries shouldn't cost too much.

General Motors wants to develop new batteries: Energy density of up to 1200 watt hours per liter

But while the Philosopher's Stone, which supposedly turns base metals into gold, is unlikely to be found, General Motors appears to be making advances in batteries with these properties.

The US automaker announced that it wanted to build a battery with a range of up to 1000 kilometers.

That would correspond almost exactly to the route from Hamburg to Vienna.

The new battery will be developed at the Wallace Battery Cell Innovation Center, which is currently under construction in Warren, Michigan.

The batteries should have an energy density of 600 to 1200 watt hours per liter of volume.

That would double to quadruple the energy density of today's batteries, which come to a value of around 300 watt hours per liter.

Applied to a VW ID.4 with a 77 kWh battery, General Motors' energy source would only take up around 65 liters of volume.

With an energy density of 300 watt hours, the battery has a volume of around 260 liters.

General Motors wants to develop new batteries: battery cells should be one meter wide

The Innovation Center will be "one of the first in North America that can use large-format prototype cells that are up to a meter wide or even wider," said Ken Morris, General Motors Vice President responsible for electric cars.

"And that means you can very easily build a vehicle that can do 500 or 600 miles on a single charge."

General Motors would not be the first car manufacturer whose Stromer can reach up to 1000 kilometers.

The Chinese manufacturer Nio has announced a range of over 1000 kilometers for its ET7 model with a 150 kWh battery pack.

However, the battery should only have an energy density of 360 watt hours per kilogram.

The energy source is correspondingly large.
