The race to build next-gen solid-state EV batteries just got a major boost, as Samsung, BMW, and Solid Power have officially teamed up to bring it to the masses.
The trio has signed an agreement to collaborate on an all-solid-state battery (ASSB) project.
This could redefine the performance, safety, and range of future electric vehicles.
Together, the companies are combining brainpower from Korea, Germany, and the United States to tackle one of the toughest challenges in EV innovation.

Solid-state EV batteries provide much longer ranges
Under the partnership, Samsung SDI will supply the cutting-edge ASSB cells, using the solid electrolyte developed by US-based Solid Power.
BMW, meanwhile, will take on the task of turning those cells into real-world battery modules and packs, ultimately integrating them into its next generation of test vehicles.
The German carmaker’s involvement is crucial here, as it provides a practical path for making solid-state batteries commercially viable.
In fact, BMW recently used an i7 to test the technology on the streets of Munich, showing its real-world capabilities.
So what makes solid-state EV batteries such a big deal?

Unlike conventional lithium-ion cells that use flammable liquid electrolytes, ASSBs use a solid electrolyte, dramatically reducing fire risks while allowing for higher energy storage.
That means lighter batteries, longer ranges, and potentially faster charging, but without the thermal drama that sometimes plagues current EV tech.
For drivers, it could mean the difference between a 300-mile and a 500-mile range, and a lot more peace of mind.
Many companies are racing to integrate this technology
Of course, these companies aren’t the only ones pursuing solid-state EV battery technology.

Toyota recently announced that it intends to launch solid-state EVs as early as 2027 to 2028.
Volkswagen also showed off its first vehicle to be powered by a solid-state battery, although it may not be what you expect.
And naturally, you can’t talk about EV technology without mentioning the Chinese carmakers, which made even Ford CEO Jim Farley feel ‘humbled’.
For instance, Huawei’s new solid-state EV battery could charge in five minutes, and deliver over 1,300 miles of range.
If this technology becomes mainstream, the days of range anxiety for EVs may finally be over.
