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 Model Y L gets disappointingly far production date in the United States
Fans of the extended wheelbase six-seater in the United States are in for a long wait.

The Tesla Model Y L is making a lot of waves in the electric vehicle community, but fans of the extended wheelbase six-seater in the United States are in for a long wait.
This was, at least, according to Tesla CEO Elon Musk, who provided a disappointingly long timeline for the Model Y L’s production in the United States.
The Model Y L
The Model Y L has received near universal acclaim from electric vehicle enthusiasts and auto reviewers in China alike. Priced at just RMB 339,000 ($47,180) and fitted with a spacious and comfortable cabin, the Model Y L seemed destined to become a segment killer. And since the vehicle is also produced in Tesla’s existing Model Y lines, it seemed like the vehicle would be released worldwide soon.
It was then no surprise that many Tesla community members were keen on asking if the Model Y L will be released in the United States anytime soon. Others also wondered why CEO Elon Musk was very quiet about the vehicle despite all the buzz it was generating. Eventually, Musk did share an update about the Model Y L, but it was not what many expected.
Elon Musk’s update
Amidst the conversations on X about the Model Y L, longtime FSD tester Whole Mars Catalog noted that Elon Musk would not be saying anything about the vehicle until its international release, likely because he would like to avoid an Osbourne Effect on the standard Model Y. Tesla’s sales today are still highly dependent on the standard Model Y, after all, as it is the company’s best-selling vehicle.
Musk responded to the FSD tester, stating that the Model Y L will not start production in the United States until the end of 2026. He also noted that the vehicle might not even make it in America at all, considering Tesla’s focus on self-driving. “This variant of the Model Y doesn’t start production in the US until the end of next year. Might not ever, given the advent of self-driving in America,” Musk wrote in his post.
Musk’s post was received with much disappointment from many X users, some of whom joked that the CEO was risking alienating families with three kids with his comments. The Model Y L, after all, is a legitimate family car that can comfortably seat six, and it seemed like a vehicle that Musk would prioritize considering his stance on people having bigger families. Of course, the CEO might still just be preventing an Osbourne Effect with his comments, but it’s difficult to deny that a 2026 U.S. production date for the Model Y L is still disappointing.

Tesla’s Elon Musk considers insane Cybertruck mod: ‘Maybe we should make this’
The Cybertruck won’t do what the video shows (at least not in our lifetime), but a very entry-level version of it could be developed.

Tesla CEO Elon Musk has teased what could potentially be the company’s next big project, and while it is likely many, many years away, it shows the company truly has its sights set on the craziest things the world has seen.
Musk shared a video created by Grok Imagine, the AI tool that is able to take images and turn them into videos, showing a Cybertruck flying above the clouds and buildings of what appears to be a very futuristic city.
There are also massive robots roaming around in the video, so it is obviously an illustration of what life could look like in several generations.
However, Musk, who does not shy away from some really optimistic projects and goals, shared the video on X and said, “Maybe Tesla should make this.”

What is depicted in the video is not what we’d see Tesla create anytime soon. However, the company could potentially engineer something to make the Cybertruck hover, as it plans to do with the Roadster.
Of course, this is likely a huge “if” considering the current state of the car industry. Vehicles are becoming more advanced with every passing day as companies like Tesla, Waymo, and others are working to sort out things like autonomous and driverless travel.
Tesla has been working on somewhat of a similar idea with the Roadster, a vehicle that has been delayed on several occasions because of Musk’s spectacular imagination. Earlier this year, Tesla’s Chief Designer, Franz von Holzhausen, revealed Musk wanted to push the limits of that vehicle even more.
It seems it could be on the way soon, considering Tesla has teased an “epic” demo for the car, which could come before the end of the year.
Tesla has been working to make the Roadster hover, using SpaceX cold gas thrusters. It will also utilize these for what could be an incredibly fast 1.1-second 0-60 MPH acceleration rate that has been teased countless times.
This project that Musk is teasing with the Cybertruck is likely one that we will not see in our lifetimes. However, this is just one example of the outlandish ideas Musk continues to tease for Tesla in the future.

Tesla Model Y L addresses one huge complaint from many owners
If you have ever used a wireless charger inside a Tesla or almost any vehicle, for that matter, you will notice that your phone will charge slowly, and it will get extremely hot. This is mostly due to the inherent inefficiency of electromagnetic induction, which is the process that wireless chargers use to transfer energy to the phone.

The new Tesla Model Y L is officially launching in China at a great price and with all of the awesome features of the original model, but with more space. The vehicle is also addressing one huge complaint that many owners have discussed.
The new Model Y L features a more spacious interior, new front seats with adjustable headrests, captains chairs, and mechanical armrests in the second row, and B Pillar air vents for improved circulation.
Tesla Model Y L officially launched: price, features, and more
However, there are some other features that are flying under the radar, including one that addresses a common complaint of many Tesla owners: wireless charging.
If you have ever used a wireless charger inside a Tesla or almost any vehicle, for that matter, you will notice that your phone will charge slowly, and it will get extremely hot. This is mostly due to the inherent inefficiency of electromagnetic induction, which is the process that wireless chargers use to transfer energy to the phone.
The inefficiency is evident in the heat, as that is the lost energy that should be going to the phone, but does not.
To combat this problem, Tesla has rolled out a new feature with the wireless charging mat in the Model Y L.
Tesla has used small slit air vents in the center of the wireless charger, which separates the two pads, to blow cool air on the phones to prevent overheating:
In a first for @Tesla, the new Model Y L has air cooled wireless phone chargers. The charging base has small slit air vents in the center that blows cool air onto your phone to prevent overheating.
The left driver’s side wireless charger now supports up to 50W charging speeds… pic.twitter.com/g6o4XgkYYE

This will keep the temperature of your phone down and could prevent the dreaded “iPhone too hot” message that deems your device unusable until it reaches a more stable temperature.
Additionally, Tesla has upgraded the driver’s side wireless charger to support 50W charging speeds. The passenger charger remains at 30W.
This is a small but valuable improvement to the wireless charging apparatus could be a game changer, as there have been so many complaints about this feature in other Tesla vehicles.
