Tesla’s Battery Day is coming tomorrow after the electric car maker’s 2020 Annual Shareholder Meeting. During the event, Tesla is expected to discuss the details of its next-generation battery cells, as well as their role in the world’s acceleration in sustainable energy. Actual details about Battery Day have been pretty scarce save for a few potential leaks, but that has not stopped the Tesla community from speculating about what the highly-anticipated event would involve.
A concise summary of the current expectations for Battery Day was recently shared by Tesla Daily’s Rob Maurer, who compiled a list of topics that the electric car maker could cover during the event. Following then is a list of expectations about what Tesla could discuss tomorrow, as the company finally shows the world what it has been working on with regards to its battery technology.
A New Cell Design
Tesla has been teasing that it would be going into the production of battery cells. So far, leaks suggest that the company is about to adopt a larger form factor for its batteries, similar to how Tesla introduced the 2170 cells for the Model 3, which were larger than the 18650 cells used in the Model S and Model X. Leaks have pointed to Tesla’s new cells possibly adopting a 54×98 form factor, which has about 10x the volume of a 2170 cell.
With larger form factors, the electrons and the ions travel larger distances as they move around in the cell, generating more friction and heat. This is a huge downside to larger cells, but Tesla’s tabless battery patent may hold the key to solving this issue. With a tabless battery cell design, the distance traveled by electrons and ions is largely reduced, limiting the disadvantages inherent among large cells. Such a design has several advantages, including better energy density and a more efficient manufacturing process.
Battery Chemistry
Speculations are abounding that Tesla may discuss the amount of silicon that it is using in the anode of its next-generation cells. The more silicon that is used, the better the energy density. However, the utilization of silicon usually results in cracked anodes over time, reducing battery performance and life. Introducing more silicon into the anode is something that battery researchers have been attempting to accomplish for a while now, so it would be quite interesting if the electric car maker would announce some headway into its silicon use as well.
Tesla may also discuss Maxwell’s technology and how it is being used for the company’s electric cars and energy storage devices. Maxwell has developed numerous innovations prior to its acquisition by Tesla, though the most relevant part of the company’s work in relation to the electric car maker is arguably its dry battery electrode tech. Considering that traditional lithium-ion batteries produce their electrodes in a wet slurry format (a rather lengthy process), dry electrode technology could vastly improve not only the energy density of Tesla’s cells, they could improve the production output of the batteries themselves as well.
Cell-to-Pack Innovations
Tesla’s battery packs today feature cells that are packed into modules that are then packed into a battery pack. Back in the days of the original Roadster, battery modules were used as a means for the company to take out parts of the battery that may need to be replaced without taking out the entire pack. That was 12 years ago, however, and much has happened since then. Tesla has transitioned from a budding niche electric car maker to the manufacturer of the market’s best-selling EVs.
As Elon Musk noted in the past, battery modules today are pretty much just an extra step, taking up weight without really serving a legitimate purpose. Musk then stated that the future is cell to pack without modules, suggesting that the company’s next-generation batteries will be using a cell-to-pack design. Such an innovation gives numerous benefits to Tesla, from lower production costs to possibly even better energy density.
Battery Manufacturing and the Roadrunner Line
Elon Musk has always been pretty transparent about Tesla’s mission, which is to accelerate the advent of sustainable energy. Having enough batteries to enable such a transition is key to this goal. With this in mind, the potential innovations that Tesla will be discussing in Battery Day — a larger form factor that would allow the company to produce fewer cells to get the same amount of energy; a tabless cell design that could make production easier; dry electrode tech that could greatly increase the production capacity density of each battery; and a cell-to-pack design that should allow the production of batteries with less equipment at less cost — could ultimately pave the way for electric vehicles and energy storage products that are significantly better than the industry standard today.
The Roadrunner project in Fremont is expected to be a central component of Tesla’s battery manufacturing plans, with attendees to the event being shown just how fast the company could produce its battery cells using its in-house production process. Elon Musk seems to be hyping the Roadrunner line recently on Twitter as well, when he made references to a game called “Factorio,” which happens to be a title focused on growing and maintaining advanced, efficient factories.
The Million-Mile Battery
The million-mile battery has been heavily speculated for Battery Day. Tesla’s electric cars are already capable of lasting long despite heavy use, but with batteries and powertrains that could last a million miles, the company could create a generation of vehicles that are designed to be always operational for an extended period of time. Million-mile batteries are then crucial for Tesla’s plans to roll out a Robotaxi service, which involves vehicles traveling long distances every year.
The Plaid Powertrain
With Tesla’s battery innovations in mind, speculations are high that the company would unveil its first vehicles that would carry its next-generation cells on Battery Day. Among Tesla’s ongoing projects, the Roadrunner cells seem to be a perfect match for cars like the Plaid Model S, Plaid Model X, and next-generation Roadster. All three vehicles have been confirmed by Elon Musk to feature the company’s upcoming “Plaid Powertrain,” which is something that has been heavily teased for some time now. Interestingly enough, updates on Tesla’s Plaid vehicles have been pretty scarce lately, making an announcement on Battery Day somewhat likely.

Xiaomi CEO congratulates Tesla on first FSD delivery: “We have to continue learning!”
Xiaomi has become one of Tesla’s strongest rivals in China.

Just days after unveiling the Xiaomi YU7, a vehicle that is considered as the Model Y’s strongest competitor yet, Xiaomi CEO Lei Jun gave a nod of respect to Tesla and its Full Self-Driving (FSD) program.
In a post on Weibo, Lei Jun highlighted the remarkable nature of Tesla’s first autonomous delivery. He also acknowledged that Xiaomi still has much to learn in the electric vehicle industry.
Xiaomi CEO’s Nod of Respect
Lei Jun’s comments about Tesla’s FSD delivery were shared as a response to Tesla VP Grace Tao’s post about the recent feat. The Tesla VP shared several key aspects of the delivery, from the fact that there was no driver in the Model Y to the vehicle reaching over 70 mph as it drove to its owner.
“For the first time in history, the vehicle was delivered to the owner by itself. There was no driver or remote control throughout the journey, and the maximum speed reached 115 kilometers per hour, and it arrived safely at the customer’s door. This is a brand new Model Y. Tesla always surpasses imagination with disruptive innovation. A new era, exciting!” Tao wrote in her post.
In his response, the Xiaomi CEO acknowledged Tesla’s incredible feat. “Tesla is indeed amazing, leading the industry trends in many areas, especially FSD. We still have to continue learning!” he wrote.


Xiaomi’s Recent Tesla Competitor
The Xiaomi CEO’s comments show that Tesla’s projects and leadership garner a lot of respect in the global electric vehicle sector. While Tesla and Elon Musk tend to be media punching bags in the United States and Europe, the company and its CEO seem to be taken very seriously in China. This was despite China being the world’s most competitive electric vehicle market.
Xiaomi itself has become one of Tesla’s strongest rivals in China, with its first car, the SU7, bringing the fight to the Tesla Model 3. Its most recent vehicle, the YU7, could very well be the Model Y’s most legitimate rival yet, as it is more affordable, bigger, and more feature-laden than Tesla’s best-selling crossover. The YU7 has garnered quite a lot of attention, with Xiaomi receiving 200,000 firm orders for the vehicle within the first three minutes of its launch.

Tesla silences FSD critics by posting full video of Model Y delivering itself to customer
When Elon Musk posted that the first Tesla had delivered itself to its owner, critics were quick to question his statement.

It is no secret that Tesla still has ardent critics today, many of whom remain convinced that the company and its leadership are lying about Full Self-Driving (FSD) and its capabilities. It was then no surprise that when Elon Musk announced that the first Tesla had successfully delivered itself to its owner, critics were quick to question the CEO’s statement.
Videos of the all-electric crossover’s solo drive to its owner soon silenced Tesla critics and their claims.
Tesla Posts FSD Video Proof—Twice
While Musk’s post on X about a Tesla delivering itself to a consumer was a notable update, his claims were not accompanied by any video. This was taken by some Tesla critics as a hint that the CEO’s claims were false, and that the feat probably did not happen. Musk, for his part, noted that Tesla would soon be posting a video of the self-driving car’s drive to its owner.
The electric vehicle community did not have to wait very long. Tesla later posted a video of its first autonomous vehicle delivery ever on X, much to the shock of social media users. As could be seen in the video, a Tesla Model Y was able to travel about 30 minutes on its own, from the end of Giga Texas’ production line to the home of its owner, several miles away. Tesla even posted the vehicle’s full 30-minute drive on its official X account later on.
Critics Are Still Skeptical, But It’s Cope at this Point
Of course, Tesla skeptics remained unconvinced that the feat was legitimate, with some pointing out that the Model Y customer seems to have had an X account for years but never posted, at least until his car was delivered. Others also claimed that the whole setup seemed suspicious since the Model Y looked like it had manufacturer plates as it navigated Austin’s streets.
These concerns, however, do not seem like very strong arguments, especially at this point. Based on the evidence, it seems like Tesla really has figured out autonomous driving, and its cars are now able to operate safely on real-world roads on their own. Many have also become silent in their criticisms of Tesla’s FSD feat, especially after the company posted the full video of the Model Y’s autonomous drive. Overall, Tesla critics may remain doubtful about the company and Musk’s claims, but these concerns seem to have become forced at best.

Ford CEO favors Waymo’s LiDAR approach over Tesla’s vision-only self-driving
Farley stated that Waymo’s LiDAR-based approach made “more sense.”

Ford CEO Jim Farley shared some skepticism about Tesla’s camera-only approach to self-driving during a recent appearance at the Aspen Ideas Festival. When asked to compare Waymo and Tesla’s autonomous driving systems, Farley stated that Waymo’s LiDAR-based approach made “more sense,” citing safety, consumer trust, and the limitations of camera-based models.
Waymo’s LiDAR vs. Tesla’s Vision-Only Approach
Farley was speaking with author Walter Isaacson when he made his comments about Tesla and Waymo’s self-driving systems. As they were conversing about autonomous cars, Isaacson asked Farley which approach to self-driving he preferred.
“To us, Waymo,” Farley said, though he also stated that both Tesla and Waymo have “ made a lot of of progress” on self-driving, as noted in a Fortune report. He also confirmed that he has had conversations about the matter with Tesla CEO Elon Musk. Despite this, he said that Ford still considers LiDAR as a pivotal part of autonomous driving.
“When you have a brand like Ford, when there’s a new technology, you have to be really careful. We really believe that LiDAR is mission critical… Where the camera will be completely blinded, the LiDAR system will see exactly what’s in front of you,” the Ford CEO stated.
Tesla and Ford’s self-driving plans
Tesla recently launched a limited Robotaxi service in Austin, which uses autonomous cars with safety monitors in the front passenger seat. While controversial, Musk has maintained that Tesla’s vision-only approach will ultimately prove safer and more cost-effective in the long term. Tesla seems to be making headway towards this goal, with Musk stating recently that the first Model Y has been delivered autonomously to a customer in Austin.
Ford, for his part, is not pursuing its own fully autonomous, urban-driving system anymore. Instead, the company is focusing on “high-speed, eyes-off” experiences like BlueCruise. Ford does plan to partner with a company that has achieved true autonomous driving in the future, as soon as the technology is available.
