Tesla’s metal-air battery patent: Carpe ‘Battery’ Diem or yesterday’s news?
Tesla was recently granted a US patent titled, “Hazard mitigation through gas flow communication between battery packs,” and with the company’s Battery Day event around the corner, anything that may foretell what the revelations will be is seeing some serious consideration. Given that this invention describes a cooling process between a combined metal-air battery pack and non-metal-air battery pack, a first glance suggests that the patent is a Roadrunner-related hint. On this particular patent, though, there’s a bit of background to consider that might not indicate what the application title plus the patent’s publication date implies.
First, U.S. Patent No. 10,763,477 was issued on September 1, 2020, and Tesla’s Battery Day is September 22, 2020; however, the patent’s filing date goes back to January 16, 2017. When it comes to inventions at the US Patent and Trademark Office (USPTO), it’s not uncommon for the legal side of the patent process to take several years to complete, and there are few options available to speed up the process. But even these simple dates don’t tell the whole story on this patent’s timeline.
In addition to being several years in the making, this patent is a continuation of another patent (U.S. Patent No. 9,548,616) which was filed in 2011 with a provisional priority date in 2010. Considering the Model S’s debut took place in June 2012, it would seem that hopes of metal-air batteries getting a Battery Day feature become a bit less bright. Of course, it might be possible that Tesla has been working on the incredible tech that CEO Elon Musk has promised for next week’s event, as he is often full of surprises. Unfortunately, that doesn’t really seem to match either the USPTO’s record of the patent’s history nor the battery-related events that have been reported over the last year for Tesla.

The core of Tesla’s most recently issued patent involves mitigating thermal runaway events that battery packs can be prone to experiencing. By introducing a metal-air battery to the overall lithium-ion vehicle battery system, a cooling method is made possible. As described in the application:
“The present invention provides a system and method for mitigating the effects of a thermal event within a non-metal-air battery pack. In accordance with the invention, the hot gas and material generated during the event is directed through the metal-air cells of a metal-air battery pack, the metal-air cells providing a large thermal mass for absorbing at least a portion of the generated thermal energy before it is released to the ambient environment, thereby lowering the risk to vehicle passengers, bystanders and first responders as well as limiting collateral property damage.”
This same description of the invention’s purpose is also included in its parent patent which has a priority filing date in 2010. While the specific claims (legal descriptions of what’s actually invented) in the recently published patent look to be a bit broader in scope than the older patent, thus indicating Tesla has either continued to develop and improve on the thermal runaway mitigation system or is trying to gain more extensive patent rights, another notable point is in the legal prosecution history at the USPTO.
The patent examiner in the case did not deem the two patents to be unique enough to have different expiration dates, and what’s called a Terminal Disclaimer was required for Tesla to be granted the patent rights. In other words, Tesla’s described battery technology in this particular case hasn’t changed significantly (according to the examiner) since it was first filed back in 2010. It may already be incorporated into the company’s current vehicles in some capacity.
Even without this patent’s promise of metal-ion battery tech as an inclusion in Battery Day revelations, there’s still plenty to look forward to. As some have dubbed the event “Master Plan Part 3,” Tesla is expected to detail its in-house production strategy and give a first look at its company-branded battery cells.

Elon Musk slams Bloomberg’s shocking xAI cash burn claims
Musk stated that “Bloomberg is talking nonsense.”

Elon Musk has forcefully rejected Bloomberg News’ claims that his artificial intelligence startup, xAI, is hemorrhaging $1 billion monthly.
In a post on X, Musk stated that “Bloomberg is talking nonsense.” He also acknowledged an X user’s comment that people “really have no idea what’s at stake” with AI.
Bloomberg‘s Allegations and Musk’s Rebuttal
The Bloomberg News report painted a dire picture of xAI’s finances. Citing people reportedly familiar with the matter, the news outlet claimed that xAI burns $1 billion a month as costs for building advanced AI models outpaced the company’s limited revenues.
Bloomberg alleged that xAI is planning to spend over half of a proposed $9.3 billion fundraising haul in three months, with a projected $13 billion loss in 2025. The report also claimed that of the $14 billion that xAI has raised since 2023, only $4 billion remained by Q1 2025. Even this amount, the news outlet alleged, will be nearly depleted in Q2.
xAI did not comment on Bloomberg‘s claims, though Elon Musk shared his thoughts on the matter on social media platform X. In response to an X user who quoted the publication’s article, Musk noted that “Bloomberg is talking nonsense.” Musk, however, did not provide further details as to why the publication’s report was fallacious.
xAI’s Bright Horizon
Despite Bloomberg‘s claims, even the publication noted that xAI’s prospects are promising. The company, now merged with X, aims to leverage the platform’s vast data archives for model training, which could reduce costs compared to rivals like OpenAI. Tapping into X also allows xAI to access real-time information from users across the globe.
xAI’s valuation reportedly soared to $80 billion by Q1 2025, up from $51 billion in 2024. The AI startup has attracted heavyweight investors such as Andreessen Horowitz, Sequoia Capital, and VY Capital so far, and optimistic projections point to profitability possibly being attained by 2027. This would be quite a feat for xAI as OpenAI, the AI startup’s biggest rival, is still looking at 2029 as the year it could become cash flow positive.

xAI supercomputer faces lawsuit over air pollution concerns
NAACP & environmental groups are suing Elon Musk’s xAI over turbine emissions at its Colossus supercomputer site.

The xAI supercomputer, Colossus, faces a potential lawsuit from the NAACP and the Southern Environmental Law Center over pollution concerns tied to its gas-powered turbines. The facility has sparked debate over its environmental impact versus economic benefits.
The xAI data center has been operational since last year. The company used pollution-emitting turbines without an air permit, citing a 364-day exemption. Southern Environmental Law Center attorney Patrick Anderson disputed xAI’s exemption, stating: “there is no such exemption for turbines — and that regardless, it has now been more than 364 days.”
The groups issued a 60-day notice of intent to sue under the Clean Air Act, challenging xAI’s permit application under review by the Shelby County Health Department.
According to AP, critics argue the turbines emit smog, carbon dioxide, nitrogen oxides, and formaldehyde, worsening health risks in an area with cancer rates four times the national average.
“The permit itself says emissions from the site ‘will be an area source for hazardous air pollutants,’” the Southern Environmental Law Center noted, alleging Clean Air Act violations.
Opponents claim xAI installed up to 35 turbines—exceeding the 15 requested—without community oversight, straining Memphis’s power grid.
xAI responded: “The temporary power generation units are operating in compliance with all applicable laws.”
The company highlighted its economic contributions, including billions in investments, millions in taxes, and hundreds of jobs. At an April community meeting, xAI’s Brent Mayo underscored that the “tax revenue will support vital programs like public safety, health, human services, education, firefighters, police, parks, and so much more.” He projected that xAI would generate over $100 million in tax revenue by next year. The company is also investing $35 million in a power substation and $80 million in a water recycling plant.
Additionally, xAI is transitioning to sustainable power, particularly Tesla Megapacks. It is actively working on demobilizing the gas turbines.
“The temporary natural gas turbines that were being used to power the [xAI’s] Phase I GPUs prior to grid connection are now being demobilized and will be removed from the site over the next two months,” shared the Greater Memphis Chamber. xAI brought Tesla Megapack batteries and a 150-megawatt substation online earlier this year.
Despite xAI’s expansion to a second 1-million-square-foot site, the lawsuit threat underscores tensions between innovation and environmental justice.

Tesla CEO Elon Musk hits back at drug use claims, calls publications ‘hypocrites’
Elon Musk showed a clean drug test, dispelling any rumors of drug use that came from unfounded reports from two large media outlets.

Tesla CEO Elon Musk has responded to a report from the Wall Street Journal and the New York Times, as both publications claimed he was abusing drugs while being involved with President Trump on both the campaign trail and while he was active within the administration after the election.
A bombshell report from the New York Times, published in late May, stated that Musk was regularly using things like ketamine, ecstasy, and psychedelic mushrooms, and also stimulants like Adderall, during his time within the Trump administration.
The reports cited inside sources who claimed the Tesla and SpaceX frontman was using substances during his time with the government.
However, Musk published the results of a recent drug test performed at Fastest Labs of South Austin. They showed ‘Negative’ results across the board:

Musk was not done there.
He went on to say the New York Times “lies as easy as breathing. It’s normal for them.” He also said both the Times and Wall Street Journal reporters should also publish their own drug test results, stating, “They won’t, because those hypocrites are guilty as sin.”
Great idea. I hereby challenge the NYT and WSJ to take drug tests and publish the results!
They won’t, because those hypocrites are guilty as sin. https://t.co/Z6kf6sj2mS

Musk said years ago that he received ketamine prescriptions from doctors to treat depression. He said he had it “years ago and said so on X, so this is not even news.” He also said that ketamine “helps for getting out of dark mental holes, but haven’t taken it since then.”
Tesla fans and Musk enthusiasts have joked for days now that, if Musk were to be on drugs, other CEOs should also do them, considering his persistence on work-related projects, long hours, and commitment to his job.
If Elon is on any drugs, I want what he’s having 🤣 pic.twitter.com/dRIuikDyym

Musk has now proven that there has been no drug use with this test, and it seems as if the reports could have some sort of legal impact, although he has not said he will take any action.
