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.

Tesla Model Y on FSD saves couple after encountering King of edge cases
Experts have noted that if confirmed, this could be the world’s first recorded meteorite collision involving a Tesla.
A South Australian Tesla driver is thanking his Model Y’s Full Self-Driving system after a mysterious object, possibly a meteorite, slammed into his car’s windshield while it had FSD engaged.
The impact sent hot glass fragments flying through the cabin as the vehicle continued driving without human input through the darkness. Experts have noted that if confirmed, this could be the world’s first recorded meteorite collision involving a Tesla.
The Tesla owner was enjoying a quiet drive home when they hit the king of edge cases
Veterinarian Dr. Andrew Melville-Smith and his wife were traveling north on Augusta Highway on the night of October 19 when a sudden blast struck their newly delivered Model Y. At the time, it was clear, pitch black night, and Dr. Melville-Smith and his wife were just listening to a podcast while FSD was operating the vehicle, as noted in a Yahoo News report.
Suddenly, something hit the Tesla’s windshield. “Then there was, (what) I can only describe as a very, very violent explosion. The whole inside of the car was literally blasted with glass fragments. It was full of white smoke, and it smelled like the car was on fire,” Dr. Melville-Smith stated.
The vet stated that he and his wife were stunned for a good 10 seconds, and for a bit, he and his wife thought they had crashed. Images of the crash’s aftermath showed a massive crack on the Tesla’s windshield, which Dr. Melville-Smith noted was hot to the touch. The object that hit the Tesla’s windshield was so hot that part of the vehicle’s windshield was partly melted.
FSD kept driving despite the possible meteorite strike
Thankfully, the Tesla was operating with its FSD (Supervised) system engaged at the time. Thus, despite the vehicle being hit by what might be a literal meteorite, and despite Dr. Melville-Smith and his wife being stunned because of the impact, their Tesla just kept driving steadily.
“I thought we’d had an accident, but then I looked at the screen and went ‘Oh, we’re still driving. We were moving around, so it obviously thought we were paying attention, and it was happy to keep driving to Port Augusta. After we pulled over, we saw the big crater in the windscreen,” the vet said.
The South Australian Museum is now examining the case, with geologist Dr. Kieran Meaney stating the scorched glass and heat damage do suggest a potential meteorite strike. “The little detail that’s really selling it for me at the moment is that whatever it was that hit the windscreen seems to have been very hot,” Meaney explained. However, the object has yet to be recovered.

“Foundation:” Elon Musk wants to send a record of Grokipedia to space
The idea sounds outlandish, though it is also something that is in character for the CEO.
Elon Musk has announced one of his latest initiatives, and it is every bit as sci-fi as it is surprisingly grounded. In a post on X, Musk stated that Grokipedia, xAI’s new open-source encyclopedia, will be etched into stable oxide and launched into space.
The idea sounds outlandish, though it is also something that is in character for the CEO.
Preserving human knowledge among the stars
Musk posted his plan following the launch of Grokipedia’s V0.1’s iteration. The CEO congratulated the xAI team for the online encyclopedia’s launch, though he also stated that the goal for Grokipedia is to create an open-source collection of knowledge. This would then be distributed to the cosmos.
“Nice work by the xAI team on Grokipedia! The goal here is to create an open source, comprehensive collection of all knowledge. Then place copies of that etched in a stable oxide in orbit, the Moon, and Mars to preserve it for the future. Foundation,” Musk wrote in his post.
While seemingly outlandish, this is not the first time that a record of human knowledge of sorts was sent out to space. In 1977, the Voyager Golden Record was launched aboard NASA’s Voyager 1 and 2 spacecraft. The record contains sounds and images that ere aggregated to portray the diversity of the Earth’s culture. Of course, Musk’s plan with Grokipedia, is infinitely more ambitious.
Grokipedia and AI neutrality
Musk launched Grokipedia as an AI-driven alternative to Wikipedia, designed to eliminate the human biases that could affect conventional online knowledge platforms. The system is powered by xAI’s Grok, which scrape and summarize information from across the internet, offering balanced and nuanced coverage of topics ranging from science and technology to culture and politics.
Unlike Wikipedia’s human-edited format, Grokipedia would be able to evolve through machine learning, reading vastly more material than any editorial team could. Early testers, including Wikipedia co-founder Larry Sanger, praised its initial version as “very OK” and potentially more neutral than Wikipedia. Musk agreed, stating that even in its V0.1 form, Grokipedia is “already better than Wikipedia.”

Tesla Cybertrucks to save Las Vegas police thousands in fuel and maintenance
Sheriff Kevin McMahill unveiled the new vehicles on Monday, describing them as “the next evolution to keep our community safer than it’s ever been.”
The Las Vegas Metropolitan Police Department has officially unveiled its fleet of Tesla Cybertrucks as part of its push toward a more advanced, cost-efficient, and sustainable patrol system.
Sheriff Kevin McMahill unveiled the new vehicles on Monday, describing them as “the next evolution to keep our community safer than it’s ever been.” The trucks are expected to begin service across all area commands within two weeks.
High-tech patrol fleet
Each UP.FIT-modified Cybertruck has been customized with ladders, shields, and less-lethal equipment to support law enforcement operations. The vehicles will connect to a live drone response hub capable of facial recognition and gunshot detection, enabling drones to launch automatically when alerts trigger. The system streams real-time footage directly to responding officers, enhancing both speed and situational awareness during emergencies.
Officers have already completed training with the new fleet and offered feedback on its performance, according to Fox 5 Vegas. Sheriff McMahill noted that the trucks, along with robot dogs and SWAT vehicles, represent a coordinated effort to combine human expertise with emerging technologies. The Cybertruck rollout was made possible through a donation from the Horowitz family.
Cybertrucks’ major savings
The department’s ten UP.FIT patrol Cybertrucks are among the most American-made law enforcement vehicles available, featuring roughly twice the domestic parts content of comparable Ford and Chevrolet patrol trucks. Beyond their build quality, the electric fleet offers major cost benefits. Each Cybertruck is projected to save between $8,800 and $12,000 in annual fuel costs and roughly $3,540 in maintenance over a five-year service life.
With regenerative braking, factory ballistic-resistant doors, and no idling fuel burn, the Cybertruck platform provides higher uptime, lower total cost of ownership, and a quieter patrol experience, all while reducing the department’s carbon footprint. Sheriff McMahill confirmed each area command will receive one of the new patrol units.
