Tesla battery supplier Panasonic aims for 20% cell density improvement by 2030
Longtime Tesla battery supplier Panasonic is working on new innovations that could increase its cells’ density by 20% by 2030. If achieved, the improvements could boost the driving range of electric vehicles even if the cars use the same battery packs they are equipped with today.
In the case of the Tesla Model Y, the improved energy density could result in the vehicle getting an extra 62 miles of range without changing its battery size. More energy-dense batteries could also allow manufacturers to design and produce electric cars that are lighter and more spacious while still offering long range.
Panasonic’s battery density targets were related to Reuters by the company’s chief technology officer, Shoichiro Watanabe, during an interview. According to Watanabe, Panasonic is looking to achieve its battery density gains through the use of new additives that would allow individual cells to run at a higher voltage without damaging performance.
“The race among battery makers has been to come up with more potent and effective additives,” the Panasonic CTO said.
A 20% increase in energy density could translate to an energy density of 900 watt-hours per liter, a substantial improvement over Panasonic’s most advanced cells today, which feature 750 watt-hours per liter. Watanabe mentioned that Panasonic is planning on achieving its battery density gains over several years, though he did not mention when the improved cells would begin their rollout.
Panasonic is extremely busy with its battery supply deal with Tesla, with the Japanese company expected to start the mass-production of the American electric car maker’s 4680 batteries during the financial year starting April 2023. Panasonic is also reportedly reviewing sites for new battery production activities in the United States.
So far, a Panasonic spokesperson has declined to provide a comment on whether the company’s new battery technologies would be incorporated in Tesla’s 2170 or 4680 cells. Tesla, for its part, has also remained silent about the matter.

Tesla all but confirms that affordable Model Y is coming Tuesday
It does appear that October 7 would be the date when the world sees Tesla’s actual idea of what an affordable vehicle would be like.

Tesla has released a cryptic teaser of a product that would be announced on Tuesday, October 7, 2025. Based on the company’s hint, it does appear that the product would be the affordable Model Y that has been spotted doing road tests across the country over the past months.
Affordable Model Y sightings
Last week, news emerged that a number of key Tesla influencers visited Gigafactory Texas for a private event. These included veteran Tesla YouTubers, car reviewers, influencers on X, and even a teardown expert who provided the initial insights on how to improve the original Model 3 sedan. At the same time, an uncovered unit of the apparent affordable Model Y was posted online. The vehicle was reportedly sighted close to Giga Texas.
The new Model Y variant had some notable changes from the standard Model Y. Its fascia seemed inspired by the Model 3 sedan instead of the Cybertruck, and its roof seemed blacked out. Overall, it looked like a simpler Model Y designed to be offered at an affordable price.
The weekend teasers
Teasers about an upcoming product were posted by Tesla’s official account on social media platform X, though the electric vehicle maker made it a point to keep things very vague. Initially, a closeup video of what appeared to be an aero wheel was posted, though it was vague enough that some speculated that it could be Elon Musk’s long-announced HVAC system instead.
On Sunday, another teaser video was posted featuring the headlights of a new car. This brought speculations that the new Roadster might finally be announced. Inasmuch as a new Roadster unveiling would be exciting, however, it was evident that the headlights in the new teaser were a match to the uncovered affordable Model Y unit that was spotted close to Giga Texas a few days ago. With this in mind, it does appear that October 7 would be the date when the world sees Tesla’s actual idea of what an affordable vehicle would be like.

Tesla releases cryptic teaser for something massive and it’s coming this week
On Sunday morning, Tesla released a nine-second teaser video of what appears to be either a vehicle wheel, fan, or some sort of propeller, but there are no real clues as to what it could be exactly.

Tesla has released a cryptic teaser for something massive, and it will release details on it this week. With many different projects in the works, there is a lot of speculation going on about what it could potentially be, but we have a few ideas.
On Sunday morning, Tesla released a nine-second teaser video of what appears to be either a vehicle wheel, fan, or some sort of propeller, but there are no real clues as to what it could be exactly.
It then ends with “10/7,” meaning it will announce something on October 7, which is this Tuesday:

Given that Tesla has been working on a handful of pretty notable projects that are set for unveiling at the end of this year, and there are some clues that seem to point in their direction with this short teaser video.
There are two projects that come to mind almost immediately: the Tesla Roadster is one, and the “E41” or affordable model is the other. Here’s what we know about both:
Tesla Roadster Demo Event
Tesla said earlier this year that it would have a demo event for the Roadster to unveil some new technologies and show off what it has been working on over the past few years.
There have been a lot of crazy things in the works for the Roadster, including a SpaceX package that would use cold-gas thrusters for an insane 1.1-second 0-60 MPH acceleration rate. This package was also supposed to help it hover, something CEO Elon Musk has teased for the past few years.
The Roadster was ready for release earlier this year, but after Chief Designer Franz von Holzhausen and VP of Powertrain Lars Moravy showed Musk what they had come up with, he wanted more.
Moravy said on the Ride the Lightning podcast earlier this year:
“What we had come up with exceeded what we originally planned. So, Elon was like, ‘Wow, great. Let’s do more!'”
The Roadster event was coined as “the most epic demo,” and since it was planned for the end of 2025, it is totally feasible to believe this could be it.
Tesla ‘E41’ Affordable Model
Some believe the teaser could be the official launch of Tesla’s affordable model, which Musk said earlier this year is simply a stripped down Model Y.
There have been some sightings of this vehicle in the past few weeks, including one on Friday that showed the vehicle completely uncovered for the first time:
🚨 It looks like the new affordable Tesla Model Y was spotted near Giga Texas

The launch of the affordable model makes sense, especially from a timing perspective. With the $7,500 EV tax credit officially coming to a close on September 30, many are wondering how Tesla will spark growth in its deliveries. A more affordable EV would be the perfect response, and it is something that Tesla has been working on for some time.
Other Potential Ideas
There are some pretty interesting ideas as to what the teaser could be apart from the Roadster or affordable model. Some believe it could be a cooling fan for a GPU cluster, which would make sense considering Tesla’s prowess in data.
Grok also made an interesting guess, stating it could be a propeller for a secret air taxi Tesla is developing. This seems sort of our of left field.
We do know Tesla hosted a handful of influencers at Gigafactory Texas this past week, so whatever the company showed them is likely what will be unveiled on Tuesday.

Tesla Optimus is learning martial arts in new video teasing capabilities
For the past few months, Tesla has been refining its capabilities and making some serious progress on what Optimus is capable of. This morning, Musk released a new video showing Optimus learning Kung Fu, perhaps its most impressive feat yet.

Tesla Optimus is learning martial arts, a new video released by CEO Elon Musk shows, a crazy development and advancement in the robotics project the company has been working on for a few years.
Optimus has been a major focus of Tesla for the past several years, especially as Musk has said he believes it will be the biggest product of all time and could be the biggest contributor to the company’s valuation.
For the past few months, Tesla has been refining its capabilities and making some serious progress on what Optimus is capable of. This morning, Musk released a new video showing Optimus learning Kung Fu, perhaps its most impressive feat yet:

The video shows Optimus working with a Kung Fu teacher, known as a Shifu, going through what appears to be some sort of routine of combinations. It’s quite impressive to see the fluidity of the movements and Optimus’s ability to keep up with Shifu.
Tesla has been “working hard” to scale Optimus production, Musk said last week, a project that has obviously confronted both AI and manufacturing teams with a variety of challenges.
The plan is to have an annual production run-rate of one million units by 2030, and there were plans to build 5,000 units this year.
Musk still believes Optimus will make up roughly 80 percent of Tesla’s value. In January, he said it would be “overwhelmingly the value of the company.”
Tesla plans to launch the Gen 3 version of Optimus soon, and although a video of a new-look prototype was released by Marc Benioff, the CEO of Salesforce, the company’s frontman stated that this was not what the next-generation prototype would look like.
Elon Musk confirms Tesla has never shown Optimus V3 design yet
This video seems to show there is still significant progress being made on the Optimus project, and it will be perhaps one of the most impressive humanoid robots available to consumers in the coming years.
