NIO’s latest filing hints at EVs powered by solid-state batteries coming as early as this summer
According to a recent filing with China’s Ministry of Industry and Information Technology, NIO intends to sell three existing EV models with expanded battery capabilities provided by solid-state battery developer WeLion. The filing matches with previous statements from NIO’s founder that consumers could see solid-state powered EVs this summer.
Although many promised EV technologies have been delivered and continue to evolve, solid-state batteries remain an aspiration by many. Although they are closer than ever, no one has yet to reach scaled production of solid-state cells… at least not to the magnitude or, more importantly, at cost parity with traditional lithium-ion batteries used by most automakers.
We at Electrek have covered the progress of several solid-state battery developers that are closer than ever to delivering commercial-grade EV-specific cells. This includes Quantumscape in the US and WeLion in China. Overseas last November, the latter company rolled its first solid-state cells off its assembly line before first deliveries to EV manufacturer NIO.
NIO’s relationship with WeLion dates back years, even before the automaker unveiled its ET7 sedan in early 2021 during a presentation that also included plans for a 150-kWh solid-state pack. We’ve seen deliveries of the NIO ET7 commence in both China and Europe, but no models with the energy-dense packs just yet.
We haven’t forgotten, and neither has NIO, as its latest filing with the Chinese government says those new battery packs may be closer to reaching the market than ever. Here’s the latest.
NIO filing hints at solid-state battery upgrades from WeLion
On May 9, China’s Ministry of Industry and Information Technology released its latest list of vehicle models slotted to be sold in the country, which also included hundreds of additional filings for specification changes on existing vehicles for public feedback – a key regulatory process in China.
As CnEVPost points out, NIO filed for an expansion of the specification information pertaining to three existing models – more specifically, the battery information section. The new filing does not mention solid-state batteries specifically but states that NIO models are receiving battery upgrades using cells from Huzhou WeLion Technology Co Ltd. – a wholly-owned subsidiary of NIO’s current semi-solid-state battery supplier, Beijing WeLion New Energy Technology.
The filing states that two NIO SUVs and one sedan will receive the battery upgrades. Recognizable vehicle names were not used. Instead, the model numbers were coded as HFC6502ECSEV9-W, HFC6502ECSEV5-W, and HFC7002CSEV1-W.
The aforementioned ET7 may not necessarily be the NIO EV to see the new energy-dense pack, but the sedan remains attached to the technology as the automaker announced plans for a 150-kWh solid-state pack during the same presentation in early 2021.
NIO hasn’t mentioned much progress since then, at least not until this past February, when the company’s founder and president, Qin Lihong, publicly stated that NIO owners will be able to start experiencing the 150-kWh pack this summer. One huge asterisk is that the 150-kWh pack could cost as much as an entire ET5 sedan, meaning cost parity with current battery chemistry remains lightyears away.
Now that the official filings have been made, it appears that at least three NIO models powered by solid-state cells are imminent and could, in fact, reach the market this summer. We won’t know for sure until we hear it directly from NIO, but this is an exciting prospect nonetheless.
Electrek’s take
Solid-state technology remains the carrot perpetually dangled in front of the EV industry and enthusiasts alike, even as it progresses. I would not be surprised at all if China is the first market to truly deliver commercially scaled solid-state cells in passenger EVs, but I’m curious about what sort of performance they will deliver in the beginning.
A 150-kWh battery pack is quite large, but with more energy-dense cells, I’d imagine NIO can deliver a similar weight (or likely less) for even more efficient power. That means lighter, less volatile EVs that will likely be able to travel further and charge faster. Or perhaps that’s optimistic reverie.
We really won’t know the scope of this battery transition and how significant it is (or isn’t) until NIO shows its cards, but it feels like it could happen in the next few months. We do know that it won’t be cheap, so I’d expect only a limited number of passenger vehicles to actually hit the roads in China.
I’m certainly getting ahead of myself, but it’s an interesting thought that if NIO does, in fact, deliver solid-state EVs in China, we could see them shipped to Europe thereafter, meaning both Chinese and EU markets could see solid-state-powered EVs driving around before the US.
Let’s wait and see what sort of heat WeLion and NIO are actually packing. I’ll keep an eye on this.

The Hyundai IONIQ 6 N is finally here, and it delivers. Hyundai’s electric sports car is loaded with fun new features, a sleek design (including a massive rear wing), 641 horsepower, and much more.
Meet the Hyundai IONIQ 6 N
After teasing the new model for the first time last month, Hyundai created quite a buzz. Now, we are finally getting our first look at the upgraded high-performance EV.
Hyundai unveiled the new IONIQ 6 N at the famed Goodwood Festival of Speed on Thursday in West Sussex, England. The upgraded model follows Hyundai’s first high-performance EV, the IONIQ 5 N.
At the event, the company boasted that its new electric sports car marks “a pivotal milestone in Hyundai N’s electrification journey,” adding “Hyundai N is once again redefining the boundaries of high-performance electrification with the debut of the IONIQ 6 N.”
The IONIQ 6 N delivers an impressive 641 horsepower (478 kW) and 77 Nm of torque, enabling a 0 to 100 km/h (0 to 62 mph) sprint in just 3.2 seconds. Its top speed is about 160 mph (257 km/h).
That’s when using Hyundai’s Launch Control, one of the many performance features the new EV offers. Like its other N models, the IONIQ 6 is based on three pillars: Corner Rascal, Racetrack Capability, and, of course, an Everyday Sportscar.
Powered by two electric motors, a 223 hp (166 kW) at the front and another 378 hp (282 kW) motor at the rear, for a combined 600 hp (448 kW).
Redefining the EV driving experience
The upgraded IONIQ 6 “redefines the EV driving experience,” according to Hyundai, thanks to its advanced in-house vehicle control software.
Central to this is Hyundai’s N Active Sound + system, which mimics the feel and sound of a traditional engine. An added N e-Shift simulates shifting gears.
And that’s just the start. Other performance features, such as N Drift Optimizer, N Grin Boost, and N Torque Distribution, give you even more control over the vehicle while delivering increased power.
The IONIQ 6 N is powered by an 84 kWh battery, providing a WLTP range of up to 291 miles (469 km). However, EPA figures will be revealed closer to launch. Given the IONIQ 5 N has an EPA-estimated range of up to 221 miles, you can expect it to be slightly higher when it arrives.
With a 350 kW DC fast charger, Hyundai’s new performance EV can recharge from 10% to 80% in about 18 minutes.
With a length of 4,935 mm, a width of 1,940 mm, and a height of 1,495 mm, the IONIQ 6 N is about the size of the Porsche Taycan.
Hyundai will showcase the new high-performance EV during the hillclimb event alongside other models like the IONIQ 5 N, IONIQ 6 N Drift Spec, and IONIQ 6 N with N Performance parts. Hyundai promises each vehicle brings unique capabilities to the event, “guaranteeing a dynamic and thrilling on-track experience for all attendees.” Check back soon for more info.
What do you think of Hyundai’s new electric sports car? Would you buy one over the Porsche Taycan? Let us know in the comments.

Elon Musk said that Tesla owners will “soon” have access to Grok, a large language developed by Musk’s xAI startup, days after the AI started calling itself ‘MechaHitler’.
Yesterday, xAI launched Grok 4, the latest version of its large language model.
The new model is benchmarking very well, but that’s generally the case with the latest model to come out. It edges the latest models from Google and OpenAI on intelligence by a few points, but it falls behind on speed:
At the launch event, Musk announced that Grok will “soon” be integrated into Tesla vehicles.
This is something that the CEO has been discussing since founding xAI, which has been controversial because Musk has also positioned Tesla to compete in the AI space. He even stepped down from his role at OpenAI due to a “conflict of interest with Tesla.”
The announcement of the imminent integration of Grok into Tesla vehicles comes just days after the language model went haywire on X and started praising Hitler, referring to itself as ‘MechaHitler’, and made several antisemitic comments.
xAI acknowledge the issue and put Grok on timeout while they fixed it:
We are aware of recent posts made by Grok and are actively working to remove the inappropriate posts. Since being made aware of the content, xAI has taken action to ban hate speech before Grok posts on X. xAI is training only truth-seeking and thanks to the millions of users on X, we are able to quickly identify and update the model where training could be improved.
The “bug” came just a few weeks after Musk stated that he was displeased with Grok supporting left-wing narratives, even though it didn’t say anything inncurate, and that he would update Grok to “fix” it.
Now, the large language model (LLM) is expected to power the new voice assistant inside Tesla vehicles.
LLMs are becoming quite common in cars, especially premium vehicles. Ford, Mercedes-Benz, Stellantis, and a few others have all integrated Chat-GPT in some models.
Many Chinese automakers have also developed their own and deployed them in cars, even entry-level ones.
Tesla is playing catch up on that front.
Electrek’s Take
As I have previously stated, I think Musk is setting up Tesla to invest or even merge with xAI at a ridiculous valuation – making Tesla shareholders virtually pay twice for Twitter, which is now part of xAI.
This is how he will be able to gain wider control over the company’s share.
Of course, it will be widely challenged in court. In fact, shareholders have already filed a lawsuit alleging that Musk was in breach of fiduciary duties to Tesla shareholders when he started xAI.

Pipeline Winding in Summer Mountain Landscape

From the first discovery in Prudhoe Bay in 1968, Alaskans have had a love-hate relationship with oil.
On one hand, it allowed Alaska to abolish its state income tax, fund most government operations and provide every Alaskan with a dividend that continues to this day. On the other hand, it has left the state at the near total mercy of the global oil market.
In recent years, that has proven to be a bad bet. And it is the major reason Alaska finishes at the bottom of the CNBC America’s Top States for Business rankings in 2025.
With the price of Alaska North Slope crude oil down by double digits from a year ago, according to the Alaska Department of Revenue, Alaska has America’s worst economy as measured by the CNBC study. Economy is the heaviest-weighted category under this year’s methodology.
Alaska’s gross domestic product growth is in the bottom ten nationally. The state’s economy grew by just 1.5% last year, compared to 2.8% nationally.
More crucially, the state’s fiscal year 2026 budget is based on a forecast of $68 per barrel for crude oil, and it is unclear if that will hold. Alaska North Slope crude traded as low as $63.49 on May 5 before rebounding above $70 in recent weeks. State forecasters are counting on oil for around 70% of the state’s revenue over the next ten years, or nearly half the state’s operating budget. And some localities are far more dependent.
“When you look at the economic engine by default,” North Slope Borough Mayor Josiah Patkotak told CNBC last month, “That happens to be oil and gas by about 98% of our operating budget.”
$40 billion bet on natural gas as diversifier
For decades, Alaska has sought ways to diversify its economy, but it has had limited success. Proposals have involved alternative energy, agriculture, and the state’s tourism sector.

In 2023, Gov. Mike Dunleavy, a Republican, signed legislation to put Alaska into the carbon market, using the state’s vast public lands for carbon storage, and to generate carbon offset credits for high carbon emitters in other states. But the program is still in the study phase. A report to the legislature in January said the program is not expected to generate any revenue until at least 2027.
More recently, the Trump administration is backing a proposal to build a natural gas pipeline alongside the Trans-Alaska oil pipeline, allowing the U.S. to ship liquid natural gas — a byproduct of North Slope oil production — to Asia.
The idea has been around for years, but the price tag, estimated at around $40 billion, was impossible for the industry to swallow even when petroleum prices were high.
Now, however, administration officials think that trade tensions might change the economics.
“There [are] countries around the world looking to shrink their trade deficit with the United States, and of course, a very easy way to do that is to buy more American energy,” U.S. Energy Secretary Chris Wright told CNBC’s Brian Sullivan in Prudhoe Bay last month.
“If you get the commercial offtakers for the gas, financing is pretty straightforward,” Wright said.
If the project gets off the ground, it could provide a huge boost to Alaska’s economy, though it would still be at the mercy of commodity prices.
Lack of tech infrastructure, high costs
Alaska’s struggling economy is a major reason for its poor competitive performance, but it is not the only one.
The state ranks No. 49 in Infrastructure. While the state’s roads and bridges are in better shape than in many states in the Lower 48, its virtual infrastructure leaves much to be desired. Fewer than 2% of Alaskans have access to affordable broadband service, according to BroadbandNow Research. The data center boom has passed Alaska by thus far, with only four in the entire state.
Alaska is a notoriously expensive place to live, especially in the many remote parts of the state.
“When you’re paying 16 bucks a gallon for milk, we’ve got to figure out how to make sure that you can afford to buy the milk so you can live here. We’ve got to make sure you can afford to buy the gas so you can hunt here,” said Patkotak.
But one aspect of life is a bargain in Alaska. At a time of soaring homeowner premiums, online insurance marketplace Insurify projects Alaska homeowners insurance premiums will average $1,543 this year, the second lowest in the nation.
Join the conversation. Didn’t see your state mentioned? You can see where it ranked overall, and in all 10 categories of competitiveness, in the full rankings of the 2025 America’s Top States for Business.
