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.

Tesla’s little-known secret about its Diner might be the best feature of all
Tesla is not letting its servers go untipped, it’s taking care of that for its employees on its own.

Tesla’s Supercharger Diner in Los Angeles has a little-known secret, and in all honesty, it might be the best part of the entire thing.
Tesla opened its Supercharger Diner earlier in June, and in its first week of operation, it has done nothing but garner attention from fans, food critics, and general onlookers who are surprised to see the company gaining traction in the culinary space.

However, there is a little-known secret about the Diner that many people have not shared, and it has to do with the staff and customers.
Traditionally, restaurants in the United States do not pay their servers a normal wage. They are paid a lower hourly rate because they make most of their money through tips or gratuity. While it is sort of strange and has recently become a more controversial topic, tipping culture in the U.S. has garnered plenty of attention lately.
Many people outside the U.S. have trouble grasping the idea of tipping servers, as many believe the restaurant should pay them a livable wage and stop relying on customers to keep the employees to a point where they can live reasonably well.
In the U.S., people seem to be on board with one side or the other: tip them because the restaurant doesn’t pay them a wage, or “I’m not tipping them for doing their jobs.”
Whichever side of the argument you’re on, I think it seems reasonable to want servers to make enough money to live comfortably and expect the restaurant to take care of that.
Tesla has done just that for the staff at the Supercharger Diner, as it has been revealed that the company covers tipping. There is no option to tip the servers or wait staff; Tesla will do it for you.

This is a great gesture by Tesla because more and more people every day seem to be against tipping in an effort to force restaurants to pay employees more money. While it seems like a good strategy at first, it only impacts the servers, while this decision does not impact the restaurant and its owners.
Tesla is taking that risk out of the equation by providing gratuity to employees through its own means.

xAI, Musk Foundation helps schools near Memphis supercomputer site
Reports of xAI and the Musk Foundation’s work were recently posted by local news media.

Elon Musk’s artificial intelligence startup xAI and the Musk Foundation have been supporting Memphis-Shelby County Schools with HVAC repairs and facility upgrades, while also funding youth programs for students in the area.
Reports of xAI and the Musk Foundation’s work were recently posted by local news media.
xAI’s school visits lead to facility repairs
Representatives from xAI visited John P. Freeman Optional School, Fairley High School, and Westwood High School, all of which are located near its Colossus supercomputer site, to assess HVAC systems, plumbing, gym facilities, and athletic fields. The visits resulted in a list of priority repairs, some of which were completed in April and May.
In addition to the repairs, xAI also shared a number of initiatives that are planned for students in the area, as stated in a Commercial Appeal report.
“xAI is working on providing STEM workshops for local students, donating equipment to technical training programs, and supporting job fairs to boost employment opportunities. These initiatives reflect xAl’s commitment to fostering education and economic growth in Memphis,” xAI noted in a statement.
Musk Foundation donation
Apart from xAI, the Musk Foundation also donated $350,000 to the Boys & Girls Clubs of Greater Memphis, enabling the reopening of two club sites located at Booker T. Washington High School and Westwood High School. Both locations had closed earlier this year due to lapses in funding. As per xAI, the Musk Foundation’s donation allows clubs to reopen for almost 1,000 students.
The donation will fund staffing, supplies, and transportation, among others. “Kids are the future of humanity,” Elon Musk said in a statement, adding that students need “every chance to shoot for the stars.”
“We’re honored to support the Boys & Girls Clubs of Greater Memphis in reopening these sites, giving kids in underserved communities the tools to build brighter futures,” Musk said.
The gift was praised by local officials, including Boys & Girls Clubs board chair Michael Garriga, who stated that the “commitment will ensure the youth of our community have the opportunities they need to develop their skills and talents to become successful students and future citizens.”

What to expect from Tesla CEO Elon Musk’s new Master Plan
While Musk only shared a few tidbits about his next plan, he did hint at its theme.

Tesla CEO Elon Musk is working on another Master Plan. The executive mentioned this during the company’s second quarter earnings call earlier this week. While Musk only shared a few tidbits about his next plan, he did hint at its theme.
Master Plan Part Four
Elon Musk’s Master Plans have been a huge guiding hand for Tesla over the past couple of decades. His first Master Plan, which was published in 2006, featured a pathway towards the production of the Model 3 and energy storage systems. Master Plan, Part Deux, which was published ten years later in 2016, featured a pathway towards a Robotaxi network.
Master Plan Part 3 was more ambitious, as it presented a case towards a world where there is sustainable energy for the entire planet. Considering the scale and ambitious nature of Master Plan Part 3, it was widely speculated that Elon Musk’s next Master Plan would not be around for some time. During the second quarter earnings call, however, Musk confirmed that he is indeed creating his next big plan.
Master Plan Part 4
Elon Musk mentioned his next Master Plan when a question was asked about the work that goes on inside the Tesla Design Studio during the Q2 2025 earnings call. In response to the inquiry, Tesla Chief Designer Franz von Holzhausen emphasized that while earnings calls are not the venue for disclosing new product-related information, Tesla is working to ensure that the future remains exciting. Musk agreed, stating that there are lots of exciting things happening in the Tesla Design Studio.
“What’s going to happen over the next several years is a fundamental transformation of the company from a pre-autonomy world to a post-autonomy. And I’m working on a new Master Plan to articulate that to the Tesla team. And there will be some teething pains as you transition from a pre- autonomy to post-autonomy world, but I think the future vision for Tesla is incredibly exciting and will profoundly change the world in a good way,” Musk said.
A Post-Autonomy World
Considering Musk’s comments, it would appear that Master Plan Part 4 will be focused on a path towards what the CEO has been describing as “sustainable abundance.” If Master Plan Part 3 was focused on fostering sustainable energy for the entire planet, Master Plan Part 4 will likely present a path towards abundance in a world populated by self-driving vehicles like the Cybercab and humanoid robots like Optimus.
Master Plan Part 4 will likely have been farfetched just a couple years ago. Yet with Tesla now operating its Robotaxi service in Austin and Optimus V3 expected to enter production next year, the idea of a world filled with “sustainable abundance” does seem quite feasible. It will be ambitious like Elon Musk’s other Master Plans, of course, but it will be attainable.
