Dreame Launches All-Solid-State Battery Sedan With Energy Density Exceeding 450Wh/kg

Recently, Dreame Technology grandly held the "Dreame Next" global launch event at the Palace of Fine Arts in San Francisco, unveiling multiple key new products and core technologies.

On the first day of the launch event, Dreame unveiled the "Rocket Car"—the Nebula NEXT 01 JET Edition. Equipped with a custom-designed dual solid rocket booster system, this new vehicle delivers an instantaneous response in just 150 milliseconds, generating a maximum thrust of 100 kilonewtons and accelerating from 0 to 100 km/h in only 0.9 seconds, shattering the performance limits of conventional automotive powertrains and becoming one of the highlights of the event.

In addition to the highly impressive "rocket car," Deebot also introduced two pure electric vehicles with different positioning. Among them, the Nebula NEXT 01X pure electric SUV is equipped with a 60Ah-level all-solid-state battery system for the first time. The official data shows its energy density exceeds 450Wh/kg. The core positioning of this vehicle is to verify the application feasibility of high-energy-density batteries in the vehicle platform, and to accumulate key data and experience for the technical implementation in subsequent mass-produced models. The Nebula NEXT 01 flagship coupe adopts a sulfide-based solid-state battery, and is also equipped with electro-hydraulic braking, electromagnetic active suspension, and a laser radar system.

Regarding solid-state batteries, Dreame has launched the “StarCore Power Battery,” a fully solid-state battery adopting the sulfide-based approach. This 60Ah ultra-high-capacity cell achieves a single-cell energy density exceeding 450 Wh/kg in laboratory tests—more than double that of conventional lithium-ion batteries—nearly doubling energy storage capacity at the same volume, and supports 1–2C fast charging, offering significant technological advantages.

ZhuiMi stated that the "Starry Sky Crystal Core Power Battery" has entered the mass production preparation stage, and will start small-scale delivery in 2026, with plans for large-scale mass production in 2027. This timeline is at least one year earlier than the 2028-2030 mass production schedules announced by industry giants such as Toyota, CATL, and BYD, fully demonstrating ZhuiMi's R&D speed and production commitment in the solid-state battery field. Notably, in 2026, ZhuiMi will also start small-scale delivery of hybrid solid-liquid batteries with energy density above 380Wh/kg and range exceeding 900km, focusing on ultra-fast charging and long-range performance, targeting the premium experience market.

The crossover by Dreame was not a spur-of-the-moment decision. As early as last August, Dreame officially announced its car-making plans, with the internal code name "Project Starry Sky." However, since the announcement, skepticism has never ceased: "What qualifies a company that makes vacuum cleaners to make cars?" "A price tag over one million, aiming to rival Bugatti, isn't this just PPT car-making?" "A solid-state battery with 450Wh/kg, mass-produced by 2027? Even CATL and BYD wouldn't dare to boast like that." Behind all these doubts, there is a general public concern about companies venturing into unfamiliar territories.

However, these doubts may underestimate ZD's technological expertise and cross-industry determination. In the field of solid-state batteries, ZD has specifically established a solid-state battery company, Jinghe Energy, which has focused on the research, development, and mass production of sulfide-based solid-state batteries since its inception, continuously increasing investment—its related technological initiatives are far from being confined to PowerPoint presentations.

In the automotive manufacturing sector, Dreame’s vehicle development team was officially launched as early as 2023. The team currently comprises 1,000 employees and is expected to approach 2,000 by the second half of this year, with approximately 70% being R&D personnel covering all domains including chassis, “three-electric” systems (battery, motor, and electronic control), and intelligent driving.

Therefore, whether Dreame’s foray into cross-industry ventures is merely an eye-catching stunt or a groundbreaking industry disruption remains too early to conclude. What is certain, however, is that at a time when the new-energy vehicle industry is rapidly evolving and global technological competition is intensifying, Dreame’s bold experimentation not only injects fresh vitality into the industry but also provides new insights for innovative development by Chinese technology enterprises.
