Mercedes-Benz has begun highway testing of an electrical automobile geared up with a next-generation solid-state battery, the corporate introduced this week.
Its lithium-based solid-state battery, constructed with battery companion Factorial, “boosts vary by 25% (focusing on ~1,000 km/620 miles) with the potential to extend vary by as much as 40%,” the corporate says.
What Is a Stable-State Battery?
As we speak’s electrical automobiles (EVs) practically all depend on lithium-ion batteries, like these in cell telephones and laptops. These batteries have pushed EVs to 9.1% of all vehicles offered within the U.S., however they’ve critical limitations.
The majority of all batteries is an power storage medium known as an electrolyte. In lithium-ion cells, this electrolyte is a heavy gel.

Researchers have developed various electrolytes which are largely stable, and far lighter. They’re much less susceptible to fireplace when broken, retailer extra power in the identical house, and cost sooner. Utilized in vehicles, their lighter weight might additionally serve to drastically enhance vary.
No automaker has but developed a solid-state battery that’s straightforward to mass-produce. Most require laboratory-like dry situations which are troublesome to copy on the dimensions of a big manufacturing facility.

Ought to an automaker resolve that drawback, they may theoretically produce lighter EVs with longer ranges that cost sooner and are safer in accidents. With longer vary doable between charging classes, widespread use of solid-state batteries might lighten the load a nation stuffed with EVs would place on electrical energy grids.
Mercedes One in every of Many Racing To Be First
Mercedes and Factorial say they now have a working prototype battery in a modified EQS sedan. “Over the following few months, Mercedes-Benz will additional take a look at the solid-state battery and its general efficiency in an electrical car with intensive laboratory and highway checks,” the pair have introduced.
That places them in competitors with…just about all the automotive trade. Most just lately, Hyundai teased the reveal of a solid-state battery, doubtless in March.
BMW, Toyota, and Stellantis all have prototypes which are in varied levels of testing. Nissan had positioned itself because the front-runner, teasing a solid-state battery that would debut within the subsequent GT-R as quickly as 2028.
Nonetheless, a lot about Nissan’s future is doubtful because it reconfigures after calling off a deliberate merger with rival Honda.
