Tesla’s 4680 battery supply chain collapses as partner writes down deal by 99%

Tesla 4680 Battery cell

A major link in Tesla’s 4680 battery supply chain has just snapped. South Korean battery material supplier L&F Co. announced today that the value of its massive supply deal with Tesla has been slashed by over 99%, signaling a catastrophic drop in demand for the automaker’s in-house battery cells.

This is arguably the strongest evidence yet that Tesla’s 4680 program, and the vehicle that relies on it, the Cybertruck, is in serious trouble.

Last call: check out these EVs before they’re gone for good in 2026

RIP: These EVs Won't Make It to 2026

A lot of mainstream auto media coverage right now is pushing the idea that some EVs are “dying.” What we’re really seeing is a wave of end-of-cycle, first-generation vehicles making way for their next-gen replacements — and, historically, that’s when buyers get the best deals.

If that’s what you’re after, these are the EVs you should be looking at right now.

It’s time to start recommending some Tesla Powerwall alternatives [update]

What options are there beyond Tesla Powerwall for home batteries?

For years, Tesla Powerwall has been the go-to recommendation for “normals” looking for a painless, low-effort experience from their first home solar and battery backup solutions. But with a recent recall on more than 10,000 home batteries over fire safety concerns following a year (or more) of CEO Elon Musk’s political antics, more and more people are beginning to look for alternatives to the trailblazing Tesla tech. The good news: there are plenty of other great home solar battery solutions are there!

UPDATE 28DEC2025: a 2026 CES Innovation Award winner makes the list.

Elon Musk drops ‘sustainable’ from Tesla’s mission as he completes his villain arc

Elon Musk Tesla Money hero

It’s official. The word “sustainable” is gone from Tesla’s mission statement.

For over a decade, Tesla’s guiding star was arguably the most impactful corporate mission statement of the 21st century. But over the last few years, we have watched the company slowly drift away from its environmental roots.

Now, Elon Musk has confirmed the final step in that divorce, rebranding the company’s goal from “Sustainable Abundance” to simply “Amazing Abundance.”

We’ve been lied to – electric bike motors CAN do regen, at least with this genius trick

If you’ve covered e-bikes as long as I have, you’ll know two things about them: they’re an awesome way to get around, and the basic technology behind an e-bike motor hasn’t radically changed in a long, long time. However, based on the new e-bike motor design I just tested from a powertrain technology company called CHARGE, the e-bike world may be about to get turned on its head. These guys discovered that nearly any e-bike hub motor can perform regenerative braking, but everyone has just been building them wrong this whole time.
