Tesla’s metal-air battery patent: Carpe ‘Battery’ Diem or yesterday’s news?

Published

on

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.

Analyst: Elon Musk’s $1 trillion Tesla pay deal modest against robot market potential

Jonas highlighted Tesla’s longer-term ambitions in robotics as a key factor in his assessment.

Morgan Stanley analyst Adam Jonas, one of Wall Street’s most ardent Tesla (NASDAQ:TSLA) bulls today, has described Elon Musk’s newly proposed $1 trillion performance-based compensation package as a “good deal” for investors. 

In a note shared this week, Jonas argued that the package helps align the interests of Musk and Tesla’s minority shareholders, despite its shockingly high headline number.

Future market opportunities

Jonas highlighted Tesla’s longer-term ambitions in robotics as a key factor in his assessment. “Yes, a trillion bucks is a big number, but (it) is rather modest compared to the size of the market opportunity,” Jonas wrote. He added that the humanoid robot market could ultimately surpass the size of today’s global labor market “by a significant multiple.”

“We have entertained scenarios where the humanoid robot market can exceed the size of today’s global labor market… by a significant multiple,” Jonas wrote, as shared on X by Tesla watcher Sawyer Merritt.

The analyst likened the arrival of AI-powered robotics to the transformative effect of electricity, noting that “contemplating future global GDP before AI robots is like contemplating global GDP before electricity.” The Morgan Stanley analyst’s insights align with the idea that as much as 80% of Tesla’s future valuation could be tied to its Optimus humanoid robot program.

Elon Musk’s pay package

Tesla’s board has tied Elon Musk’s proposed compensation package to some of the most ambitious targets in corporate history. The 2025 CEO Performance Award requires the automaker’s valuation to soar from roughly $1.1 trillion today to $8.5 trillion over the next decade, a level that would make Tesla the most valuable company in existence.

The plan also demands a leap in Tesla’s operating profit, from $17 billion in 2024 to $400 billion annually. It also ties the CEO’s compensation to a number of product milestones, including the delivery of 20 million vehicles in total, 10 million active Full Self-Driving subscriptions, 1 million Tesla Bots, and 1 million Robotaxis in operation. Tesla’s board emphasized that Musk’s leadership was fundamental to achieving such ambitious goals, with Chair Robyn Denholm noting the award would align the CEO’s incentives with long-term shareholder value.

Tesla posted 14,300 insurance registrations in China during the week of September 1–7, a 14.4% increase from the previous week’s 12,500 units. 

The figure marks Tesla’s highest weekly performance so far this quarter so far, despite the company’s year-over-year figures still being below 2024’s numbers.

Weekly registrations

The week’s registrations broke down to 5,000 Model 3s and 8,400 Model Ys, including the first 900 units of the newly launched Model Y L variant, as per estimates from industry watchers. On a quarterly basis, Tesla China is tracking 41.3% growth compared to the previous quarter, which bodes well for the company’s results this Q3 2025.

For the month of August, Tesla sold 57,152 vehicles in China, down 9.93% from the same period in 2024 but up 40.7% from July’s 40,617 units, according to the China Passenger Car Association (CPCA). Year-to-date, Tesla’s China sales are 7.2% lower compared to the previous year.

Model Y L first deliveries

The week ending September 7 was the first week that included the newly released Model Y L, a six-seat extended wheelbase version of the company’s best-selling all-electric crossover. Industry watchers estimate that last week, the first 900 units of the Model Y L have been registered, though this number is expected to increase in the coming weeks as deliveries of the vehicle hit their pace.

Citing information from a Tesla store in Beijing, Chinese media outlet Cailianshe stated that the Model Y L has been seeing a lot of interest among car buyers. “(The Model Y L) is selling very well. Since its launch, 120,000 orders have been received, with nearly 10,000 orders placed every day. The first batch of customers began receiving deliveries in the past two days,” a Tesla representative stated.

Tesla has introduced MultiPass, a new feature that allows owners to use their Tesla account to charge at non-Tesla charging stations. 

The service launched this week in the Netherlands, giving drivers the ability to find chargers, start sessions, and view charging history directly within the Tesla app.

Streamlining third-party charging

With MultiPass, Tesla owners can activate charging either through the Tesla app or by using their existing Tesla key card. This eliminates the need for separate accounts or additional cards from third-party networks. Tesla Charging highlighted the convenience of managing charging sessions in one location in a post on X, while Max de Zegher, Tesla’s Director of Charging for North America, emphasized that the update removes unnecessary friction.

“Nobody likes creating more accounts with payment details and passwords. For charging, this can even mean needing a third-party charging card mailed to your house. Starting in the Netherlands today, your Tesla App and your existing (!) Tesla keycard can start charging at third-party chargers. We’ll expand this to more countries quickly if customers love it. To make ownership effortless, the Tesla App should really be the only thing you need,” the Tesla executive wrote in a post on X.

Third-party payments and a familiar name

Tesla owners could pay for their third-party charging session with their Tesla accounts, as per the electric vehicle maker on its official website. Payments are drafted from users’ default payment method in the Tesla App, though charging costs will still vary depending on the third-party charger that is used.

Interestingly, the MultiPass name also echoes a pop culture reference. In the 1997 sci-fi film The Fifth Element, Leeloo Dallas-505 carried a futuristic “Multipass” smart card that functioned as her ID, passport, and ticket to space travel. Her accented repetition of “Multipass!” became one of the film’s most memorable lines, and it highlighted the card’s all-in-one convenience.

Tesla has not provided a timeline for Multipass’ U.S. rollout, though the service could become an important addition to the growing but often fragmented landscape of DC fast charging.
