Tesla's Dry Cathode 4680 Battery Cells Will Mean Cheaper, Better EVs

Not a Tesla App

During the 2024 Shareholder Meeting, Elon Musk announced that Tesla has made new innovations on the 4680 cell standard. Tesla has been working hard for several years to get a functional 4680 cell in production that either matches or beats the performance of the existing 2170 cell. The official Cybertruck account also shared an image (below) of the first 4680 dry-cathode process Cybertruck with its production crew on X.

We’re going to take a bit of a dive into the 4680, what exactly this new process and cell is, and then some of its possible advantages. So, grab your charging cable!

What is the Dry Process?

Dry Battery Electrode (DBE) is a different process overall from the current Wet Battery Electrode (WBE) that is common today. This dry process removes the highly toxic solvents and furnace baking processes from the equation, saving both time and space, while also being environmentally friendly.

The Dry Cathode we’re talking about specifically means that the electrode – the conducting terminal at the edges of the battery – is produced in a dry process. In the previous process, it was produced with a wet process.

Tesla’s 4680 cell suppliers – LG and Panasonic – have both been working hard to cut down on costs and ramp up their own 4680 cell production while Tesla works on their own internal improvements as well. If Tesla has found a means to easily scale the Dry Cathode method, it’ll make 4680 cells and the batteries that they are a part of - cheaper to produce.

Tesla has used the 4680 cells to make structural battery packs for the Model Y. However, these vehicles had poor charging performance and lower energy density, and they were quickly removed from sales. The sheer size of the 4680 cell made it difficult to cool, limiting its performance.

The updated 4680 cell was announced at the November 2023 Earnings Call as Cybercell, making a comeback for the Cybertruck. This new version was going to have better energy density, as well as improved charging performance.

Sandy Munro of Teardown Titan fame showed that this improved version has about a 12% energy density increase, a pretty significant improvement. You can watch his teardown of the Cybertruck below.

Tabless Design

The tabless design of the 4680 cell also has an impact on its production, and how easy it is to manufacture. Think of the tabs as the little nubs on the top of a regular small battery. The lack of tabs means that production of the cell body doesn’t have to pause to add the tabs, reducing the chance for defects with the elimination of a process, and making it faster to boot.

Removing the tab also helps in cutting down the distance that electrons have to travel to get in and out of the cell – this means less resistance, and less energy lost in the process, increasing overall vehicle efficiency.

Advantages

This new 4680 cell process has a few advantages – including an overall cost reduction of up to 50% compared to the current wet process. That’s in addition to the dry process being more environmentally friendly, which will also allow for manufacturing of the cell to scale quicker.

Tesla wants to move from the standard 2170 cell to the 4680 cell for several reasons. The biggest, by far, is cost savings. The 4680 cell is physically a bigger cell and can be used to structurally support the vehicle, meaning cost savings on both, the production of the 4680 cell and the structure of the vehicle.

Easy and Cheap

There’s more too – the 4680 cell will be easier to manufacture because of its bigger size. The 2170 cell is tall and thin, while the 4680 cell is wide and stout. In addition, its unique tab-less design is supposed to generate less resistance, improving charging speeds and cell performance.

Essentially, Tesla can fill the space taken up by 4,400 2170 cells with only 960 4680 cells. This results in a significant reduction in the material used to encase each individual cell, thereby saving space and maximizing energy density for the space the battery pack takes up.

All in all, that could mean a future price drop for the Cybertruck as well as increase the rate of production. Tesla has envisioned producing approximately 250,000 Cybertrucks per year, and they’ll need a lot of 4680 battery packs to do so.

In the future, we can see Tesla bringing the 4680 cell with all these improvements - and more - to the rest of its vehicle lineup, as they will eventually surpass the 2170 cell technology.

Tesla FSD in Europe: June Update

Not a Tesla App

The road to bringing FSD to Europe has been a long and complex one and filled with regulatory and bureaucratic hurdles. Elon Musk, as well as other members of Tesla’s AI team, have previously voiced their grievances with the regulatory approval process on X.

However, it appears that there is finally some progress in getting things moving with recent changes to upcoming autonomy regulations, but the process still seems slow.

Waiting on the Dutch

Elon commented on X recently, stating that Tesla is waiting for approval from Dutch authorities and then the EU to start rolling out FSD in Europe. Tesla is focusing on acquiring approvals from the Dutch transportation authority, which will provide them with the platform they need to gain broader acceptance in Europe. Outside of the Netherlands, Tesla is also conducting testing in Norway, which provides a couple of avenues for them to obtain national-level approval.

The frustration has been ongoing, with multiple committee meetings bringing up autonomy regulation but always pulling back at the last second before approving anything. The last meeting on Regulation 157, which governs Automated Lane Keeping Systems, concluded with authorities from the UK and Spain requesting additional time to analyze the data before reaching a conclusion.

Tesla, as well as Elon, have motioned several times for owners to reach out to their elected representatives to move the process forward, as it seems that Tesla’s own efforts are being stymied. 

This can seem odd, especially since Tesla has previously demoed FSD working exceptionally smoothly on European roads - and just did it again in Rome when they shared the video below on X.

DCAS Phase 3

While the approval process has been slow, Kees Roelandschap pointed out that there may be a different regulatory step that could allow FSD to gain a foothold in Europe.

According to Kees, the European Commission is now taking a new approach to approving ADAS systems under the new DCAS Phase 3 regulations. The Commission is now seeking data from systems currently operational in the United States that can perform System-Initiated Maneuvers and don’t require hands-on intervention for every request.

This is key because those are two of the core functionalities that make FSD so usable, and it also means that there may not be a need to wait years for proper regulations to be written from scratch. Now, the Commission will be looking at real-world data based on existing, deployed technology, which could speed up the process immensely.

What This Means

This new, data-driven regulatory approach could be the path for Tesla to reach its previous target of September for European FSD. While the cogs of bureaucracy are ever slow, sometimes all it takes is a little data to have them turn a bit faster in this case.

Alongside specific countries granting approval for limited field testing with employees, there is some light at the end of the tunnel for FSD in Europe, and hopes are that a release will occur by the end of 2025. With Europe now looking to North America for how FSD is performing, Tesla’s Robotaxi results could also play a role.

The Contest

The core of the contest is simple. Create a video that shows how your Tesla gives you more in life. Tesla is looking for submissions that highlight themes of freedom, safety, fun, and convenience.

Prizes

The prizes definitely make this contest worth entering if you’re good with a camera and have some basic video editing abilities.

For North America, the prizes include a brand new Model Y AWD Long Range, alongside an all-expenses-paid trip to Austin for a tour of Giga Texas. The grand prize winner will also be able to custom order their Model Y, allowing them to select their preferred wheels and color.

The two runners-up won’t get a Model Y, but they’ll also enjoy an all-expenses-paid trip to Giga Texas for a tour of the factory.

The travel and tour include lodging in Austin for 2 nights, as well as economy-class round-trip tickets from anywhere in North America. Tesla will also provide a vehicle for use during the trip.

Hopefully, these winners will also have the opportunity to experience the Robotaxi network while they’re in Austin, as it’s expected to be opened to the public later this month.

Project Loveday

For long-time followers of Tesla, this contest may feel familiar. The contest is a direct throwback to the 2017 Project Loveday contest, which was inspired by a letter to Tesla from a 10-year-old aspiring marketer. That contest was won by MKBHD, with his submission below:
