Solid-state EV batteries with +1,800 miles range? It sounds too good to be true
Another company claims to have solid-state EV batteries in the works that will unlock well over 1,000 miles (3,000 km) of range and fast charging in just five minutes. And it’s not BYD this time. Is it too good to be true?
Can solid-state EV batteries unlock +1,000 miles range?
Last week, a local report surfaced, claiming BYD was already testing solid-state batteries in its Tesla Model 3-rivalling Seal sedan.
BYD addressed the rumors in a statement released on Monday (via CLS), saying, “Currently it is unknown, and the first model and parameters are not officially reported.”
In a new patent, discovered by CarNewsChina, Chinese tech giant Huawei filed for a sulfide-based all-solid-state battery. The new battery reportedly unlocks a driving range of up to 3,000 km, or over 1,800 miles, and supports ultra-fast charging in just five minutes.
Is it really possible, though? To put that into perspective, the current longest-range electric vehicle you can buy, the 2025 Lucid Air Grand Touring, is rated with a WLTP driving range of up to 839 km (521 miles).
On the EPA scale, Lucid’s electric sedan is rated for a driving range of up to 512 miles and features fast charging (up to 200 miles) in 12 minutes.
That would mean Huawei’s new battery would unlock over three times the driving range while cutting charging times by over half. It would also have energy density that’s two to three times higher, between 400 and 500 kWh.
According to industry experts in Korea, the claims might be too good to be true. Yang Min-ho, professor of energy engineering at Dankook University, explained that “Even the most advanced lithium-ion batteries, which generally have higher capacity than solid-state prototypes, fall far short of that kind of range.”
Yang said that “Such performance might be possible in lab conditions,” adding “but real-world factors like energy loss and thermal management make mass production extremely difficult.”
The patent describes a new approach, doping sulfide electrolytes with nitrogen, to improve stability. According to a researcher for one of Korea’s major battery makers, the nitrogen doping approach is “a standard technique with limited scalability.”
“While nitrogen doping can help with interface stability, it’s usually done under vacuum and with great precision,” the researcher pointed out, adding “It’s not something you can scale for commercial production without major cost and time penalties.” They described it as “like trying to sprinkle pepper on a sandwich using tweezers.”
Although it sounds promising, Huawei’s patent needs additional third-party validation or other data to suggest it’s production-ready. “That’s the nature of patents. They grant rights, not credibility.”
According to the researcher, Korean battery giants, LG Energy, Samsung SDI, and SK On, don’t seem too worried. “We monitor developments in China closely, but this doesn’t look like a game-changer yet,” they said.
Samsung SDI has already sent solid-state battery samples to clients and aims to begin mass production by 2027: LG Energy and SK On both plan to introduce solid-state battery tech by 2030.
Are solid-state EV batteries capable of delivering ultra-long driving range as promised? It may, but it could be a few years before it hits the market. As Yang said, “Battery science doesn’t move in leaps. It moves in increments, and those increments take years to scale.”
Meanwhile, several automakers and others are also advancing solid-state EV batteries, promising longer driving range and faster charging.
Mercedes-Benz announced it had tested “the first car powered by a lithium-metal solid-state battery on the road” with Factorial Energy earlier this year using a modified EQS. Last month, BMW completed its first on-road tests using Solid Power’s all-solid-state battery (ASSB) cells. CATL, Stellantis, Nissan, Volkswagen, and Nissan have also announced plans to launch EVs with solid-state batteries in the next few years.
Will the “holy grail” of EV batteries live up to its hype? Let us know your thoughts in the comments below.

BYD Yangwang launches ultra-swanky U8L SUV with 24k gold emblems (don’t worry, this one floats too)
BYD’s ultra-luxury sub-brand, Yangwang, launched its fourth all-electric model in China, and it’s another design marvel. Like its U8 predecessor, the Yangwang U8L SUV has “Emergency Float Mode.” Plus, this one can tank turn, is powered by four motors, and has 24-karat emblems. Check out one of the most expensive new BEVs in China.
Yangwang, which directly translates to “looking up” or “admire,” is an ultra-premium brand under the BYD umbrella introduced in 2023. The luxury-centric marque turned some heads out of the gate at the 2023 Shanghai Auto Show, where it unveiled the U8 SUV, which can go amphibious in emergencies and crabwalk.
Since then, Yangwang has followed up with a 1,200-horsepower electric supercar called the U9, hands down the most beautiful vehicle I saw during my visit to the 2025 Shanghai Auto Show.
In early 2024, Yangwang unveiled its first sedan, the 500-mile range U7, to complete an initial trio of flagship models. By August, we learned Yangwang was hard at work on a fourth model – a third-row variant of the U8 SUV called the U8L – which promised to be longer and even more luxurious.
Today, Yangwang officially launched the U8L in China, beginning in a single “Dingshi Edition” trim that starts at RMB 1.28 million ($179,800) – debuting as one of the most expensive models amongst all Chinese automakers.
Yangwang U8L offers Rolls-Royce-style luxury
Today’s launch marks Yangwang’s deeper push into the luxury SUV market in China, looking to compete against brands like Mercedes-Benz and Range Rover. Yangwang’s new U8L takes the U8 to another level, offering more space and other comforts.
For example, the Yangwang U8 measures 5,319 mm long, 2,050 mm wide, and 1,930 mm tall, with a wheelbase of 3,050 mm. In comparison, the new U8L measures 5,400 mm long, 2,049 mm wide, and 1,921 mm tall, with a wheelbase of 3,250 mm.
The longer length and wheelbase allow for a new third row atop BYD’s e4 platform, which also houses four electric motors. That powertrain configuration combines for 880 kW (1,180 horsepower) and peak torque of 1,280 Nm, accelerating from 0 to 100 km/h (0-62 mph) in 3.5 seconds. Not bad for an SUV.
Per Yangwang, the U8L also comes equipped with BYD’s DiSus-P body control system—the Chinese automaker’s most advanced version, enabling premium comfort and stability on any terrain. The U8L also features BYD’s most advanced ADAS, “God’s Eye A.” In the images above, multiple sensors are visible above the windshield.
Other features include emergency flotation mode, blown tire stability, tank turns, and a crabwalk. Plus, fully reclining seats, window privacy curtains, and a rear storage fridge for your Cristal. Due to its size, the Yangwang U8L’s all-electric CLTC range is only 200 km (124 miles), but it features a hybrid range extender that boosts its overall range to 1,160 km (700 miles).

The bZ7 is about the size of a Tesla Model S and way nicer than you’d expect. Toyota’s new flagship EV is not only stunning-looking, it’s also loaded with advanced tech.
Meet the bZ7, Toyota’s new flagship EV
Toyota’s joint venture in China, GAC-Toyota, unveiled official images of the bZ7 this week, its new flagship all-electric sedan.
The bZ7 is 5,130 mm long, which is slightly longer than the Tesla Model S and BYD Han L. Although it has Toyota’s updated “hammerhead” front end design, like the new Camry and Crown, the flagship EV is a big step up from the Toyota vehicles we see on the road today.
Toyota said its new EV has “a luxurious and elegant figure,” and we’d have to agree. From the side, it has a sleek, fastback design that blends sporty and elegant. The long, triangular side windows open up the interior.
The bZ7 is also Toyota’s most advanced EV yet. It will be the first vehicle to feature Xiaomi’s “Human x Car x Home” smart ecosystem, which unlocks new functions such as controlling smart home appliances directly from the vehicle’s infotainment system or your smartphone.
Forgot to set the air? Xiaomi’s smart tech allows you to control it on the go. During its tech day event in June, Toyota announced new partnerships with Xiaomi, Momenta, and Huawei, or what it called the “car industry bigwigs,” for the latest tech and software.
The bZ7 has a Lidar installed on the roof, which will be used to support Momenta’s latest smart driving system, Momenta 6.0. It’s expected to be offered on higher trim options.
On the inside, the cabin is a step change from most Toyota models with a minimalist, elegant layout. It features a floating central touchscreen, a driver display screen, and a wireless phone charger.
Toyota’s flagship EV will also use Huawei’s electric motors and its new HarmonyOS cockpit system. According to Li Hui, the General Manager of Toyota China, “To deliver cars that people want in China, we need Chinese brains and hands involved in development.
We will learn prices, battery specs, and range closer to the bZ7’s official debut, which is expected later this year. Toyota’s new flagship EV will join the bZ3X and bZ4X as it fights for its spot in China’s competitive electric vehicle market.
