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 is offering a crazy choice on the Model 3 to help with its end-of-quarter push, but it is only available in Canada.

Tesla has been offering some pretty crazy incentives to help move vehicles in various markets, including discounts, Supercharging, and other offers.

In Canada, it is offering something pretty crazy: a $5,000 discount or Free Supercharging for life:

This would bring the price of the two Tesla Model 3 configurations:

  • Tesla Model 3 RWD – $49,990
  • Tesla Model 3 LRAWD – $56,990
  • Tesla Model 3 Performance – $64,990

The offer only stands if delivery is taken by September 30. The company describes the terms and conditions:

“Orders will default to $5,000 off total purchase price, deducted pre-tax. Requires you to contact Tesla to switch promotion to free Supercharging if desired. Supercharging promotion is tied to your Tesla Account and cannot be transferred to another vehicle, person or order, even in the case of ownership transfer. Used vehicles and vehicles used for commercial purposes (like taxi, rideshare and delivery services) are excluded from this promotion. You are still responsible for Supercharger fees, like idle and congestion fees, when applicable. Redeemable only at Tesla-owned Superchargers. Tesla reserves the right in its sole discretion to remove the free Supercharging from your vehicle in the event of excessive charging. “

The $5,000 discount in Canada, or the unlimited Free Supercharging, is a massive deal, as it benefits those looking for a deal or those who plan to use the car as a daily driver.

Tesla offers new deal on used inventory that you won’t want to pass up

Tesla has used a lot of different deals this quarter to help push cars out and bolster Q3 delivery figures.

  • Lifetime Free Supercharging or $5,000 discount on Model 3 in Canada
  • 1 Year Free Supercharging on Inventory Cybertruck, Model S, Model X in the U.S.
  • 18 Months free Supercharging on Model 3 in the U.S.
  • Lifetime Free Supercharging with Luxe Package on Model S and Model X in the U.S.
  • Up to $2,000 off Model 3 and Model Y Inventory in the U.S.

These deals have all contributed to an increase in demand and minimal vehicle inventory in various markets.

Wall Street firm makes shock move for Tesla Q3 delivery prediction

“[The company should have] strong deliveries in the US as Tesla pushes, and consumers take advantage of, the $7,500 IRA EV tax credit before its expiry at the end of September 2025.”

A Wall Street firm is making a shocking move ahead of Tesla’s Q3 delivery report, increasing its forecast for the quarter.

Tesla is set to report its deliveries for the third quarter sometime next week at the beginning of October. There has been quite a bit of speculation about Tesla’s performance in terms of deliveries for the quarter, as many firms and investors are curious about how strong it could be.

There have been a few things working in Tesla’s favor, including the removal of the $7,500 EV tax credit, which stimulated demand as consumers wanted to take advantage of the discount before it was no longer available.

Tesla also has launched an attractive revamp to the Model Y this year, which was the best-selling car in the world for the past two years. These two points have helped Tesla with demand specifically this year, but this quarter has been especially strong because of the tax credit phase-out.

With that being said, one Wall Street firm chose to push its delivery prediction for the third quarter up about ten percent.

Tesla makes a big change to reflect new IRS EV tax credit rules

UBS analysts said they adjusted their delivery targets for Tesla from 431,000 to 475,000, stating it was “more in line with buyside expectations in the 470-475k range.”

The firm continued:

“[The company should have] strong deliveries in the US as Tesla pushes, and consumers take advantage of, the $7,500 IRA EV tax credit before its expiry at the end of September 2025.” 

If it manages to reach what UBS thinks it will, deliveries would be the highest for Tesla since late 2024, and the firm believes it could “potentially [be] the highest ever” for the company in a single quarter.

Tesla delivered over 495,000 cars in Q4 2024, so it would truly need an anomaly to capture that crown in Q3.

For the full year, UBS believes Tesla will deliver 1.62 million cars in 2025.

Tesla’s ‘Unboxed Process’ patent highlights affordability through efficiency

The process includes utilizing past methods that Tesla has brought into automotive manufacturing, including Gigacasting and structural battery integration, with more efficient “post-manufacturing” processes, like pre-painting.

Tesla has been granted a new patent for its “Unboxed Process” of manufacturing, which aims to enhance affordability for customers by increasing efficiency at the manufacturing stage.

This is one way the company aims to create a larger impact from start to finish, especially with upcoming vehicles. For those who are not familiar, the Unboxed Process was first unveiled by Tesla back in 2023 during its “Investor Day.”

The company brought forth the idea that vehicle manufacturing could shift from traditional assembly lines, making production more efficient, more cost-effective, and more scalable for the future, especially with mass-market models like Cybercab.

The process includes utilizing past methods that Tesla has brought into automotive manufacturing, including Gigacasting and structural battery integration, with more efficient “post-manufacturing” processes, like pre-painting.

Tesla describes the main advantages in the patent:

“The present disclosure relates to an automated system and method for assembling exterior vehicle parts to a vehicle assembly structure. The system utilizes an automated assembly cell with fixtures corresponding to each exterior vehicle part and references a global datum for precise alignment…The method improves assembly efficiency by compensating for substructure irregularities with an engineered adhesive gap and allows for continued assembly during adhesive curing through tacking operations.”

Instead of traditional welding strategies, the company plans to use a different bonding method, through adhesives.

The patent goes on:

“In described examples, a modular vehicle architecture allows for the assembly of a vehicle in sections, which are then joined in a final assembly operation. This approach eliminates the traditional need for welding stamped panels and applying secondary coatings or painting at the full vehicle assembly level. Instead, the vehicle can be constructed in parts, with metal surface treatments like e-coating and painting applied beforehand.”

The goal behind this manufacturing process is that Tesla will be able to build more vehicles at a faster rate for a lower price, something it believes it will need to accomplish as it addresses autonomy and Robotaxis, which are in higher demand.

With this rate of speed of manufacturing, Tesla says traditional manufacturing methods have the potential consequence of “compounding errors,” as “any slight misalignment or variance can add up.”

There is a refined focus on efficiency, while also recognizing the importance of build quality. This should eliminate most of the issues Tesla would confront with its current, more traditional, linear manufacturing processes.
