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 China breaks 8-month slump by selling 71,599 vehicles wholesale in June
Tesla China’s June numbers were released by the China Passenger Car Association (CPCA) on Tuesday.

Tesla China was able to sell 71,599 vehicles wholesale in June 2025, reversing eight consecutive months of year-over-year declines. The figure marks a 0.83% increase from the 71,599 vehicles sold wholesale in June 2024 and a 16.1% jump compared to the 61,662 vehicles sold wholesale in May.
Tesla China’s June numbers were released by the China Passenger Car Association (CPCA) on Tuesday.
Tesla China’s June results in focus
Tesla produces both the Model 3 and Model Y at its Shanghai Gigafactory, which serves as the company’s primary vehicle export hub. Earlier this year, Tesla initiated a changeover for its best-selling vehicle, the Model Y, resulting in a drop in vehicle sales during the first and second quarters.
Tesla’s second-quarter China sales totaled 191,720 units including exports. While these numbers represent a 6.8% year-over-year decline for Tesla China, Q2 did show sequential improvement, rising about 11% from Q1 2025, as noted in a CNEV Post report.
For the first half of the year, Tesla sold 364,474 vehicles wholesale. This represents a 14.6% drop compared to the 426,623 units sold wholesale in the first half of 2024.
China’s competitive local EV market
Tesla’s position in China is notable, especially as the new Model Y is gaining ground in the country’s BEV segment. That being said, Tesla is also facing competition from impressive local brands such as Xiaomi, whose new YU7 electric SUV is larger and more affordable than the Model Y.
The momentum of the YU7 is impressive, as the vehicle was able to secure 200,000 firm orders within three minutes and over 240,000 locked-in orders within 18 hours. Xiaomi’s previous model, the SU7 electric sedan, which is aimed at the Tesla Model 3, also remains popular, with June deliveries surpassing 25,000 units for the ninth straight month.
While China’s EV market is getting more competitive, Tesla’s new Model Y is also ramping its production and deliveries. Needless to say, Tesla China’s results for the remaining two quarters of 2025 will be very interesting.

Tesla reveals it is using AI to make factories more sustainable: here’s how
Tesla is using AI in its Gigafactory Nevada factory to improve HVAC efficiency.

Tesla has revealed in its Extended Impact Report for 2024 that it is using Artificial Intelligence (AI) to enable its factories to be more sustainable. One example it used was its achievement of managing “the majority of the HVAC infrastructure at Gigafactory Nevada is now AI-controlled” last year.
In a commitment to becoming more efficient and making its production as eco-friendly as possible, Tesla has been working for years to find solutions to reduce energy consumption in its factories.
For example, in 2023, Tesla implemented optimization controls in the plastics and paint shops located at Gigafactory Texas, which increased the efficiency of natural gas consumption. Tesla plans to phase out natural gas use across its factories eventually, but for now, it prioritizes work to reduce emissions from that energy source specifically.
It also uses Hygrometric Control Logic for Air Handling Units at Giafactory Berlin, resulting in 17,000 MWh in energy savings each year. At Gigafactory Nevada, Tesla saves 9.5 GWh of energy through the use of N-Methylpyrrolidone refineries when extracting critical raw material.
Perhaps the most interesting way Tesla is conserving energy is through the use of AI at Gigafactory Nevada, as it describes its use of AI to reduce energy demand:
“In 2023, AI Control for HVAC was expanded from Nevada and Texas to now include our Berlin-Brandenburg and Fremont factories. AI Control policy enables HVAC systems within each factory to work together to process sensor data, model factory dynamics, and apply control actions that safely minimize the energy required to support production. In 2024, this system achieved two milestones: the majority of HVAC infrastructure at Gigafactory Nevada is now AI-controlled, reducing fan and thermal energy demand; and the AI algorithm was extended to manage entire chiller plants, creating a closed-loop control system that optimizes both chilled water consumption and the energy required for its generation, all while maintaining factory conditions.”
Tesla utilizes AI Control “primarily on systems that heat or cool critical factory production spaces and equipment.” AI Control communicates with the preexisting standard control logic of each system, and any issues can be resolved by quickly reverting back to standard control. There were none in 2024.
Tesla says that it is utilizing AI to drive impact at its factories, and it has proven to be a valuable tool in reducing energy consumption at one of its facilities.

Tesla analysts believe Musk and Trump feud will pass
Tesla CEO Elon Musk and U.S. President Donald Trump’s feud shall pass, several bulls say.

Tesla analysts are breaking down the current feud between CEO Elon Musk and U.S. President Donald Trump, as the two continue to disagree on the “Big Beautiful Bill” and its impact on the country’s national debt.
Musk, who headed the Department of Government Efficiency (DOGE) under the Trump Administration, left his post in May. Soon thereafter, he and President Trump entered a very public and verbal disagreement, where things turned sour. They reconciled to an extent, and things seemed to be in the past.
However, the second disagreement between the two started on Monday, as Musk continued to push back on the “Big Beautiful Bill” that the Trump administration is attempting to sign into law. It would, by Musk’s estimation, increase spending and reverse the work DOGE did to trim the deficit.
Every member of Congress who campaigned on reducing government spending and then immediately voted for the biggest debt increase in history should hang their head in shame!
And they will lose their primary next year if it is the last thing I do on this Earth.
— Elon Musk (@elonmusk) June 30, 2025
President Trump has hinted that DOGE could be “the monster” that “eats Elon,” threatening to end the subsidies that SpaceX and Tesla receive. Musk has not been opposed to ending government subsidies for companies, including his own, as long as they are all abolished.
How Tesla could benefit from the ‘Big Beautiful Bill’ that axes EV subsidies
Despite this contentious back-and-forth between the two, analysts are sharing their opinions now, and a few of the more bullish Tesla observers are convinced that this feud will pass, Trump and Musk will resolve their differences as they have before, and things will return to normal.
ARK Invest’s Cathie Wood said this morning that the feud between Musk and Trump is another example of “this too shall pass:”

Additionally, Wedbush’s Dan Ives, in a note to investors this morning, said that the situation “will settle:”
“We believe this situation will settle and at the end of the day Musk needs Trump and Trump needs Musk given the AI Arms Race going on between the US and China. The jabs between Musk and Trump will continue as the Budget rolls through Congress but Tesla investors want Musk to focus on driving Tesla and stop this political angle…which has turned into a life of its own in a roller coaster ride since the November elections.”
Tesla shares are down about 5 percent at 3:10 p.m. on the East Coast.
