'Holy grail' solid-state batteries have started to move from the lab to reality in the US

Racing China to release the first ‘Holy grail’ solid-state batteries, the US manufacturer Karma Automotive and technical gurus Factorial Energy are set to begin rolling out the new power units to a 1,000hp ultra-luxury EV.

Battery technology is the bread and butter of EV manufacturing.

So far, lithium-ion batteries have powered our cars, but with ranges on some new EVs reaching over 700 miles, it looks like we’ve reached the ceiling for what they are capable of.

Now, in the race to get solid-state batteries on the market, the US has taken a major step into the fast lane.

Karma Automotive targets solid-state EV launch in 2027

Founded in 2014, Karma Automotive has had a turbulent tenure as a manufacturer, with a few top-range models to its name but with very limited sales.

However, the company recently revealed the Kaveya ‘super-coupe’, revealing that it will be one of the most powerful cars made in the United States.

Now, it’s claimed that the new model will be arriving in 2027 and will be powered by solid-state batteries.

In a statement, the company revealed that its partnership with Factorial Energy ‘brings this transformative technology from the laboratory to the road,’ and the Kaveya will be supported by this breakthrough.

The super-coupe promises over 1,000hp and a 0-60mph time of under three seconds.

How will the battery work?

Interestingly, the Kaveya only claims to have a range of around 270 miles, which is extremely short for a new lithium-ion car, never mind a solid-state.

However, in the case of a performance car like this, it’s all about greater efficiency.

Being able to support quicker charging times, reducing thermal management issues, and using its lighter weight to support aerodynamics, the car will use these solid-state batteries in a different way than a luxury SUV would.

But that’s the point of these new power banks. Improved versatility.

It will also mark the first American car to use these units in a passenger car – however, one company claims to have motorbikes ready to go by April this year, after taking to CES 2026 to showcase the Verge TS Pro.

Solid-State batteries are the future

Solid-state batteries have been mostly pioneered in China so far.

Despite not producing them in cars yet, the powerunits entered production in November 2025.

The first car, the MG4, is set to release later this year for over six figures, while several manufacturers are closely following behind.

But the Karma Automotive partner, Factorial Energy, is also set to power European cars from BMW and Porsche, too.

It will be a landmark moment for the US, and you can bet your bottom dollar the likes of Tesla, Hennessey, and Ford are all taking note.
