Mercedes-Benz has begun highway testing of an electrical automobile outfitted with a next-generation solid-state battery, the corporate introduced this week.
Its lithium-based solid-state battery, constructed with battery associate Factorial, “boosts vary by 25% (concentrating 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?
In the present day’s electrical automobiles (EVs) almost all depend on lithium-ion batteries, like these in cell telephones and laptops. These batteries have pushed EVs to 9.1% of all automobiles offered within the U.S., however they’ve severe limitations.
The majority of all batteries is an vitality storage medium referred to as an electrolyte. In lithium-ion cells, this electrolyte is a heavy gel.

Researchers have developed various electrolytes which can be largely stable, and far lighter. They’re much less inclined to fireside when broken, retailer extra vitality in the identical area, and cost sooner. Utilized in automobiles, their lighter weight may 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 can be troublesome to copy on the dimensions of a giant manufacturing unit.

Ought to an automaker clear up that downside, they might theoretically produce lighter EVs with longer ranges that cost sooner and are safer in accidents. With longer vary attainable between charging periods, widespread use of solid-state batteries may 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 check the solid-state battery and its general efficiency in an electrical automobile with intensive laboratory and highway exams,” the pair have introduced.
That places them in competitors with…just about your complete automotive business. Most not too long ago, Hyundai teased the reveal of a solid-state battery, possible in March.
BMW, Toyota, and Stellantis all have prototypes which can be in varied phases of testing. Nissan had positioned itself because the front-runner, teasing a solid-state battery that might debut within the subsequent GT-R as quickly as 2028.
Nevertheless, a lot about Nissan’s future is doubtful because it reconfigures after calling off a deliberate merger with rival Honda.
