Recent observations by active members of the Tesla community suggest that the electric car maker may have acquired a lithium-ion battery cell specialist startup from Louisville, Colorado. If these speculations prove accurate, Tesla may very well be on the cusp of extending its lead in the electric vehicle market further. 

It is no secret that Tesla is always in the process of improving its battery cells. The company has expressed its intentions to start producing its own cells, even if it has to dip its toes in the mining business to get there. Interestingly, Tesla currently has job listings for “cell technicians” in Louisville, Colorado. The job’s requirements include, among other things, a background in electrode coating and cell assembly, suggesting that Tesla may be looking into battery innovations and cell manufacturing. 

As observed by TSLA retail investor Galileo Russell of YouTube’s Hyperchange channel, Louisville, Colorado happens to be a hotbed for next-generation battery startups, and several of them are working on lithium-ion technology. Some of these, such as battery startup Forge Nano, have already received investments from automakers such as Volkswagen. But among these, a company called SilLion Inc. may very well be the perfect fit for Tesla. 

SilLion is a small company that is specifically working on battery high-loading silicon anode and electrode technology for commercial cylindrical cells. The company’s tech delivers a breakthrough in high-energy batteries by simultaneously incorporating high-loaded silicon anodes, nickel-rich NMC cathodes, and a non-flammable ionic liquid electrolyte. Doing so allows batteries to be more energy-dense and safer while being cheaper to produce. Tesla, of course, just happens to be one of the few automakers that use cylindrical cells for its vehicles.

SilLion Inc. has since taken down its official website, unlike some of the other battery startups in Louisville. Some of the company’s employees, such as Research Scientist Simon Hafner, now list Tesla as an employer in their LinkedIn pages as well. SilLion co-founders Daniela Molina Piper and Tyler Evans have also listed Tesla in their interests in the professional social media platform. Looking at these, one can be compelled to speculate that Tesla may have acquired (or perhaps acqui-hired) SilLion Inc, and the electric car maker may be working on including the startup’s technology in its next-generation of batteries.

Tesla is no stranger to acquiring small companies whose work can improve the electric car maker’s innovations. Last year, Tesla used this exact same strategy with its DeepScale acquisition. DeepScale is pretty small, with a headcount of just about 40 employees, but it is working on technology that allows deep neural networks to work on smaller devices. The company’s Carver21 product, for one, was specifically designed to optimize the processing data from a full self-driving car’s forward-facing cameras. These innovations are valuable for Tesla, especially amidst the company’s push for Full Self-Driving. 

Whether Tesla has indeed acquired SilLion remains to be seen. That being said, one will be hard-pressed to find a reason why technology developed by the Louisville-based battery startup will not benefit the electric car maker. Ultimately, these speculations will likely be addressed soon, when Tesla holds its highly-anticipated Battery Day.

Tesla Full Self-Driving gets sparkling review from South Korean politician

“Having already ridden in an unmanned robotaxi, the novelty wasn’t as strong for me, but it drives just as well as most people do. It already feels like a completed technology, which gives me a lot to think about.”

Tesla Full Self-Driving got its first sparkling review from South Korean politician Lee So-young, a member of the country’s National Assembly, earlier this week.

Lee is a member of the Strategy and Finance Committee in South Korea and is a proponent of sustainable technologies and their applications in both residential and commercial settings. For the first time, Lee was able to utilize Tesla’s Full Self-Driving technology as it launched in the country in late November.

Her thoughts on the suite were complimentary to the suite, stating that “it drives just as well as most people do,” and that “it already feels like a completed technology.”

Her translated post says:

“Finally, today I got to experience Tesla FSD in Seoul. Thanks to the Model S sponsored by JiDal Papa^^, I’m truly grateful to Papa. The route was from the National Assembly -> Mangwon Market -> Hongik University -> back to the National Assembly. Having already ridden in an unmanned robotaxi, the novelty wasn’t as strong for me, but it drives just as well as most people do. It already feels like a completed technology, which gives me a lot to think about. Once it actually spreads into widespread use, I feel like our daily lives are going to change a lot. Even I, with my license gathering dust in a drawer, don’t see much reason to learn to drive a manual anymore.”

Tesla Full Self-Driving officially landed in South Korea in late November, with the initial launch being one of Tesla’s most recent, v14.1.4.

It marked the seventh country in which Tesla was able to enable the driver assistance suite, following the United States, Puerto Rico, Canada, China, Mexico, Australia, and New Zealand.

It is important to see politicians and figures in power try new technologies, especially ones that are widely popular in other regions of the world and could potentially revolutionize how people travel globally.

Tesla dispels reports of ‘sales suspension’ in California

“This was a “consumer protection” order about the use of the term “Autopilot” in a case where not one single customer came forward to say there’s a problem.

Sales in California will continue uninterrupted.”

Tesla has dispelled reports that it is facing a thirty-day sales suspension in California after the state’s Department of Motor Vehicles (DMV) issued a penalty to the company after a judge ruled it “misled consumers about its driver-assistance technology.”

On Tuesday, Bloomberg reported that the California DMV was planning to adopt the penalty but decided to put it on ice for ninety days, giving Tesla an opportunity to “come into compliance.”

Tesla enters interesting situation with Full Self-Driving in California

Tesla responded to the report on Tuesday evening, after it came out, stating that this was a “consumer protection” order that was brought up over its use of the term “Autopilot.”

The company said “not one single customer came forward to say there’s a problem,” yet a judge and the DMV determined it was, so they want to apply the penalty if Tesla doesn’t oblige.

However, Tesla said that its sales operations in California “will continue uninterrupted.”

It confirmed this in an X post on Tuesday night:

The report and the decision by the DMV and Judge involved sparked outrage from the Tesla community, who stated that it should do its best to get out of California.

One X post said California “didn’t deserve” what Tesla had done for it in terms of employment, engineering, and innovation.

Tesla has used Autopilot and Full Self-Driving for years, but it did add the term “(Supervised)” to the end of the FSD suite earlier this year, potentially aiming to protect itself from instances like this one.

This is the first primary dispute over the terminology of Full Self-Driving, but it has undergone some scrutiny at the federal level, as some government officials have claimed the suite has “deceptive” naming. Previous Transportation Secretary Pete Buttigieg was vocally critical of the use of the name “Full Self-Driving,” as well as “Autopilot.”

New EV tax credit rule could impact many EV buyers

We confirmed with a Tesla Sales Advisor that any current orders that have the $7,500 tax credit applied to them must be completed by December 31, meaning delivery must take place by that date. However, it is unclear at this point whether someone could still claim the credit when filing their tax returns for 2025 as long as the order reflects an order date before September 30.

Tesla owners could be impacted by a new EV tax credit rule, which seems to be a new hoop to jump through for those who benefited from the “extension,” which allowed orderers to take delivery after the loss of the $7,500 discount.

After the Trump Administration initiated the phase-out of the $7,500 EV tax credit, many were happy to see the rules had been changed slightly, as deliveries could occur after the September 30 cutoff as long as orders were placed before the end of that month.

However, there appears to be a new threshold that EV buyers will have to go through, and it will impact their ability to get the credit, at least at the Point of Sale, for now.

Delivery must be completed by the end of the year, and buyers must take possession of the car by December 31, 2025, or they will lose the tax credit. The U.S. government will be closing the tax credit portal, which allows people to claim the credit at the Point of Sale.

We confirmed with a Tesla Sales Advisor that any current orders that have the $7,500 tax credit applied to them must be completed by December 31, meaning delivery must take place by that date.

However, it is unclear at this point whether someone could still claim the credit when filing their tax returns for 2025 as long as the order reflects an order date before September 30.

If not, the order can still go through, but the buyer will not be able to claim the tax credit, meaning they will pay full price for the vehicle.

This puts some buyers in a strange limbo, especially if they placed an order for the Model Y Performance. Some deliveries have already taken place, and some are scheduled before the end of the month, but many others are not expecting deliveries until January.
