Tesla debuts new 4680 battery cell: 500% more energy, 6X power, range increase

Published

on

Tesla CEO Elon Musk and Vice President of Technology Drew Baglino have unveiled a new 4680 battery cell. The cell, which is already being produced at the company’s Kato Road pilot facility in Fremont, is the automaker’s big breakthrough in the company’s quest to create a more affordable electric car.

The two Tesla executives detailed the company’s new cell, which aims to not only decrease production costs, but also increase energy density, power, and range for its electric vehicles. The new tabless battery design will increase manufacturing efficiency, leading to decreased cost per kilowatt-hour.

Tesla’s new cell will decrease the amount of time needed to charge. This challenge was confronted by a balance of the cells’ outer diameter in millimeters described by the first two digits of the new cell.

Tesla showed where the tabless battery design was more efficient in terms of charging and size. The 46-millimeter tabless system showed to be most efficient in terms of charging efficiency. It was apparent by Tesla’s several graphics during the Battery Day event that a tabless cell was the best design as it would decrease the time of charging.

The 46 millimeters wide, 80-millimeter long battery cell will increase energy density by five times, increase range by sixteen percent, and improve power output by six times.

Additionally, Musk and Baglino indicated that the company is already working on producing the cell at the Kato Road facility. Tesla is “starting to ramp up production at our pilot 10 GWh factory just around the corner,” Musk said.

It will take around one year for the Kato Road facility to reach its 10 GWh production capacity.

The efficiency in the manufacturing process of the new cell will also reduce the price per kWh by 14%. This price reduction ultimately helps Tesla move closer toward the goal of price parity with gas-powered cars. To create a more affordable electric vehicle, battery cells must become cheaper to produce. Manufacturing cells in mass amounts and having them become readily available for vehicle production will decrease the cost of the car, and will lead to Tesla’s EVs being as affordable, or even more affordable, than gas-powered competitors.

The widely accepted number for price parity with gas vehicles is $100 per kWh. While it is unknown what the current cost is, a 14% reduction in cost would likely make Tesla’s cars as affordable as gas cars. The most recent estimates from Forbes have narrowed down Tesla’s most likely cost at $127 per kWh.

This is just the beginning. Tesla’s cell efficiency could reduce the cost per kWh by 14%, but the ultimate goal is to reduce it by 50%. This goal can be accomplished by increasing the manufacturing of cells through company factories, increasing the efficiency of anode and cathode materials, and cell vehicle integration.

Tesla China’s domestic sales fell 4.8% in 2025, but it’s not doom and gloom

Despite the full-year dip, Tesla finished the year with record domestic sales in December.

Tesla posted 625,698 retail vehicle sales in China in 2025, marking a 4.8% year-on-year decline as the EV maker navigated an increasingly competitive EV market and a major production transition for its best-selling vehicle. 

Despite the full-year dip, Tesla finished the year with record domestic sales in December.

Retail sales slip amid Model Y transition

Tesla’s 2025 retail sales in China were down from 657,102 units in 2024, when the company ranked third in the country’s new energy vehicle (NEV) market with a 6.0% share. In 2025, Tesla’s share slipped to 4.9%, placing it fifth overall, as noted in a CNEV Post report.

Part of the decline seemed tied to operational disruptions early in the year. Tesla implemented a changeover to the new Tesla Model Y in the first quarter of 2025, which required temporary production pauses at Giga Shanghai. That downtime reduced vehicle availability early during the year, weighing on the company’s retail volumes in China and in areas supplied by Giga Shanghai’s exports.

China remained one of Tesla’s largest markets, accounting for 38.24% of its global deliveries of 1.64 million vehicles in 2025. However, the company also saw exports from Giga Shanghai fall to 226,034 units, down nearly 13% year-on-year. It remains to be seen how much of this could be attributed to the Model Y changeover and how much could be attributed to other factors.

Strong December 2025 finish

While the full-year picture showed some contraction, Tesla closed 2025 on a high note. According to data from the China Passenger Car Association (CPCA), Tesla China delivered a record 93,843 vehicles domestically in China in December, its highest monthly total ever. That figure was up 13.2% from a year earlier and 28.3% higher than November.

The surge was driven in part by Tesla prioritizing domestic deliveries late in the year, allowing buyers to lock in favorable purchase tax policies. In December alone, Tesla captured 7.0% of China’s NEV market and a notable 12.0% share of the country’s battery-electric segment.

On a wholesale basis, Tesla China sold 851,732 vehicles in 2025, down 7.1% year-on-year. From this number, 97,171 were from December 2025 alone. Tesla Model 3 wholesale figures reached 312,738 units, a year-over-year decrease of 13.12%. The Tesla Model Y’s wholesale figures for 2025 were 538,994 units, down 3.18% year-over-year.

Tesla Robovan’s likely first real-world use teased by Boring Company President

As per the executive, the vehicle will be used to move large crowds through Las Vegas during major events.

The Boring Company President Steve Davis has shared the most likely first real-world use for Tesla’s Robovan.

As per the executive, the vehicle will be used to move large crowds through Las Vegas during major events. 

Tesla Robovan for high-demand events

During a feature with the Las Vegas Review-Journal, Boring Company President Steve Davis stated that the Tesla Robovan will be used in Sin City once the Vegas Loop expands across the Strip and downtown and the fleet grows to about 1,200 Teslas. 

At that scale, Robovans would primarily be deployed during predictable surges, such as game days and large shows, when many riders are traveling to the same destination at the same time.

“The second you have four (passengers) and you have to start stopping, the best thing you can do is put your smallest vehicle in, which is a car. But if you know people are going to the stadium because of a game, you’ll know an hour before, two hours before, that a lot of people are going to a game or a Sphere show, if you are smart about it, that’s when you put a high occupancy vehicle in, that’s when you put the Robovan in,” Davis said.

Vegas Loop expansion

Steve Davis’s Robovan comment comes amid The Boring Company’s efforts to expand the Vegas Loop’s airport service. Phase 1 of rides to Harry Reid International Airport began last month, allowing passengers to travel from existing Loop stations such as Resorts World, Encore, Westgate, and the Las Vegas Convention Center.

Phase 2 will add a 2.2-mile dual-direction tunnel from Westgate to Paradise Road. That section is expected to open within months and will allow speeds of up to 60 mph on parts of the route, while expanding the fleet to around 160 vehicles.

Future phases are expected to extend tunnels closer to airport terminals and add multiple stations along University Center Drive. At this point, the system’s fleet is expected to grow close to 300 Teslas. The final phase, an underground airport station, was described by Davis as the system’s “holy grail.” This, however, has no definite timeframe as of yet.

Tesla is hiring an iOS Engineer for its Robotaxi app team, with the job posting emphasizing the creation of polished experiences that make the service not just functional, but “magical.”

Needless to say, it appears that Tesla is hard at work in ensuring that users of its Robotaxi service are provided with the best user experience possible.

Robotaxi App features

As observed by Tesla community members, Tesla has gone live with a job listing for an iOS Engineer for its Robotaxi App. The job listing mentions the development of a “core mobile experience that enables customers to summon, track, and interact with a driverless vehicle. From requesting a ride to enabling frictionless entry, from trip planning to real-time vehicle status and media control.”

Interestingly enough, the job listing also mentioned the creation of polished experiences that make the Robotaxi more than just functional. “You will take full ownership of features—from architecture design to robust implementation—delivering delightful and polished experiences that make Robotaxi not just functional, but magical,” Tesla noted in its job listing.

Apple’s “magical” marketing

Tesla’s use of the word “magical” when referring to the Robotaxi app mirrors the marketing used by Apple for some of its key products. Apple typically uses the word when referring to products or solutions that transform complex technology into something that feels effortless, simple, and natural to daily life. Products such as the AirPods’ seamless pairing with the iPhone and FaceID’s complex yet simple-to-use security system have received Apple’s “magical” branding.

With this in mind, Tesla seems intent on developing a Robotaxi app that is sophisticated, but still very easy to use. Tesla already has extensive experience in this area, with the Tesla App consistently being hailed by users as one of the best in its segment. If Tesla succeeds in making the Robotaxi app worthy of its “magical” branding, then it wouldn’t be a surprise if the service sees rapid adoption even among mainstream consumers.
