Tesla’s cobalt-free efforts are being closely watched by LG Chem, Samsung ahead of Battery Day
It appears that it is not only the electric vehicle community that is eagerly anticipating Tesla’s upcoming Battery Day event. Considering the company’s place in the EV movement, as well as its efforts in pursuing a cobalt-free solution for batteries, industry leaders like Samsung and LG Chem are reportedly watching Tesla and its battery announcements closely.
Battery Day has been mentioned by Elon Musk multiple times in the past, and last month, the company noted that the highly-anticipated event will be held on September 22. The CEO has informed analysts that Battery Day will include a “big reveal” of developments in Tesla’s battery efforts. The effects of such developments on the battery supply chain are also expected to be discussed.
Tesla has kept details of Battery Day secret, though industry officials have noted that details on new cobalt-free batteries will be revealed at the upcoming event. Tesla has been working on reducing its batteries’ cobalt content for years, as evidenced by a study from a German firm that determined that Model 3 batteries have 75% less cobalt than the cells used by companies like Volkswagen. In the second-quarter earnings call, Elon Musk noted that eventually, cobalt will be phased out completely.
EV battery makers such as LG Chem and Samsung have mostly favored nickel manganese cobalt (NMC) or nickel cobalt aluminum (NCA) batteries over cobalt-free lithium iron phosphate (LFP) chemistry due to their higher energy density, which allows vehicles to travel longer distances. LFP batteries are more environmentally-friendly and cost-effective, but they tend to be limited when it comes to range. This status quo seems poised to change with Battery Day, at least if speculations prove accurate.
Reports have emerged stating that CATL, one of Tesla’s battery partners in China, has begun supplying LPF batteries for the electric car maker’s locally-produced Model 3. Elon Musk emphasized this in the Q2 2020 earnings call, when he stated that Tesla will be boosting volume production in China of LFP battery packs for the Model 3. By the end of July, Panasonic, Tesla’s longtime battery partner, informed Reuters that it will be commercializing a cobalt-free battery in two to three years for the electric car maker.
Amidst these reports, industry leaders like LG Chem and Samsung are now facing what could very well be a crossroads with their battery strategy. If Tesla has come up with a way to solve the shortcomings of LFP batteries, there is a good chance that the battery industry could also start moving away from cobalt. Tesla, after all, is one of the world’s leading electric car maker, and its EV and energy storage business are both undergoing an aggressive expansion. Cobalt is also a controversial material to begin with, thanks to questionable mining practices in areas such as the Congo.
That being said, LG Chem has stated that it still believes that NMC chemistry will remain the mainstream in the global market due to its energy density advantages. “Though we are producing LFP batteries too, these have their shortcomings in energy density and weight. We believe NCM will remain the mainstream in the global EV battery market,” the company stated during its second-quarter conference call.
Samsung SDI was on the same page, stating that it will be focusing on NCA technology. Citing an industry official who requested anonymity, The Korea Times noted that Samsung is paying close attention to what Tesla will be announcing and unveiling on Battery Day.
“Many battery firms have tried to upgrade the energy density of LFP chemistry, but they have yet to have meaningful outcomes. Tesla is now saying it is increasing its reliance on LFP batteries and is anticipated to come up with information on new cobalt-free batteries during Battery Day. This can either mean that Tesla and CATL have come up with technology to improve the efficiency of LFP batteries or unprecedented technology in removing cobalt,” he said. “Since either way will likely affect the industrial trend, domestic companies are paying attention to what Tesla will reveal during the event,” the industry insider stated.
Tesla’s Battery Day event is expected to be held on September 22, 2020. A live audience is expected to be present, though the event will also be live-streamed.

Tesla FSD V14.2 starts rolling out to initial batch of vehicles
It would likely only be a matter of time before FSD V14.2 videos are posted and shared on social media.
Tesla has begun pushing Full Self-Driving (Supervised) v14.2 to its initial batch of vehicles. The update was initially observed by Tesla owners and veteran FSD users on social media platform X on Friday.
So far, reports of the update have been shared by Model Y owners in California whose vehicles are equipped with the company’s AI4 hardware, though it would not be surprising if more Tesla owners across the country receive the update as well.
Based on the release notes of the update, key improvements in FSD V14.2 include a revamped neural network for better detection of emergency vehicles, obstacles, and human gestures, as well as options to select arrival spots.

The Tesla Model X has always been one of the company’s most loved vehicles, despite its low sales figures, which can be attributed to its high price tag.
However, the Model X has been a signature item on Tesla’s menu of cars, most notably recognized by its Falcon Wing Doors, which are aware of its surroundings and open according to what’s around it.
But recent improvements to the Model X were looking slim to none, but it appears most of the fixes actually happened under the body, at least according to Tesla’s Vice President of Powertrain, Lars Moravy.
In a recent interview with Car and Driver, Moravy detailed all of the changes to the 2026 iteration of the vehicle, which was about 400 pounds lighter than it was originally. The biggest change is a modification with the rear motor, switching from an induction-type motor to a permanent-magnet design and optimizing the half-shafts, which shed about 100 pounds.
Tesla also got “almost 80 pounds out of the interior bits and pieces,” which “included making parts thinner, different manufacturing process choices, and incorporating airbag-deployment requirements into the headliner fabric,” the report said.
Additionally, the standard five-passenger, bench seat configuration saved 50 pounds by ditching pedestal mounting. This also helped with practicality, as it helped the seat fold flat. Engineers at Tesla also saved 44 pounds from the high-voltage wiring through optimizing the wiring from the charge-port DC/DC converter and switching from copper to aluminum wiring.

Tesla also simplified the cooling system by reducing the number of radiators. It also incorporated Nürburgring cooling requirements for the Plaid variant, which saved nearly 30 pounds.
Many Tesla fans will be familiar with the megacastings, manufactured in-house by presses from IDRA, which also saves more than 20 pounds and boosts torsional stiffness by around 10 percent. Tweaks to the suspension also saved 10 pounds.
People were truly disappointed with what Tesla did with the Model S and Model X, arguing that the cars needed a more severe exterior overhaul, which might be true. However, Tesla really did a lot to reduce the weight of the vehicle, which helps increase range and efficiency. According to Grok, every 200 pounds removed adds between 7 and 15 percent to range estimations.
This makes sense considering the range estimations both increased by 7 percent from the Model X’s 2025 configuration to the 2026 builds. Range increased on the All-Wheel-Drive trim from 329 miles to 352 miles, while the Plaid went from 314 miles to 335 miles.
Tesla has officially launched its first branded Supercharger just months after initiating a new program that allows third-party companies to brand their own charging piles.
The site opened in Land O’ Lakes, Florida, and features eight V4 Supercharging stalls offering up to 325 kW of charging speed. It appears it was purchased by a company called Suncoast Credit Union. This particular branch is located Northeast of Tampa, which is on the Gulf of Mexico.
It features graphics of Florida animals, like alligators:

Tesla launched this program back in September, and it basically was a way to expand its Supercharger presence and also allow companies to pay for the infrastructure. Tesla maintains it. When it announced the “Supercharger for Business,” it said:
“Purchase and install Superchargers at your business. Superchargers are compatible with all electric vehicles, bringing EV drivers to your business by offering convenient, reliable charging.”
The program does a few things. Initially, it expands EV charging infrastructure and makes charging solutions more readily available for drivers. It can also attract people to those businesses specifically.

The chargers can also be branded with any logo that the business chooses, which makes them more personalized and also acts as an advertisement.
The best part is that the customers do not have to maintain anything about the Supercharger. Tesla still takes care of it and resolves any issues:
“We treat your site like we treat our sites. By providing you with a full-service package that includes network operations, preventative maintenance, and driver support, we’re able to guarantee 97% uptime–the highest in the industry.”
It appears the Superchargers will also appear within the in-car nav during routing, so they’ll be publicly available to anyone who needs to use them. They are still available to all EVs that have worked with Tesla to utilize its infrastructure, and they are not restricted to people who are only visiting the business.
