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.

OpenAI cites distrust of SpaceX in decision to drop Cursor partnership
OpenAI will cut SpaceX-owned Cursor’s model access in November, citing Musk’s history of broken contracts.
OpenAI, the company behind ChatGPT, announced late Friday that it is ending its partnership with Cursor, cutting off the coding tool’s access to its models on November 12. The move comes two weeks after SpaceX completed its $60 billion acquisition of Cursor’s parent company, Anysphere, folding the popular AI coding assistant into Elon Musk’s growing SpaceXAI division.
In a post on its website, OpenAI said the decision came down to trust, not technology. “We cannot be confident that SpaceX will use our technology within our terms of service, based on our experience with Elon Musk’s companies violating contracts,” the company wrote. OpenAI pointed to two specific incidents: X, now part of SpaceX, allegedly breaking the terms of an existing OpenAI contract after Musk bought Twitter.
That lawsuit is the backdrop for all of this. Musk cofounded OpenAI in 2015, left the board in 2018, and sued Sam Altman and Greg Brockman in 2024, arguing they abandoned the company’s nonprofit mission for profit. A federal jury sided with OpenAI in May, finding Musk waited too long to sue rather than ruling on the merits of his claims. Musk said at the time he would appeal to the Ninth Circuit, calling the outcome a “calendar technicality” rather than a real judgment.
SpaceX’s interest in Cursor predates that verdict by weeks. The company first struck a deal with Cursor in April, securing an option to acquire it for $60 billion or pay $10 billion for joint development work instead. As Teslarati reported at the time, the logic was straightforward: Cursor was paying retail prices to Anthropic and OpenAI, two of its most direct competitors, every time a developer used its product, while SpaceX had idle capacity on its Colossus supercomputer, roughly the equivalent of a million Nvidia H100 GPUs, that Cursor could use to train its own models instead. SpaceX exercised the option in June, days after its own IPO, and the deal closed in mid-August.
Once it closed, Musk moved fast. On an all-hands call with more than 1,000 Cursor employees, he reportedly told staff that SpaceXAI’s Grok was playing catchup in the AI race, unlike Tesla and SpaceX in their own markets, and singled out Anthropic as the company to catch. Cursor CEO Michael Truell now reports directly to Musk inside SpaceXAI.
Losing OpenAI’s models leaves Cursor leaning harder on Anthropic’s Claude, which has its own compute agreement with SpaceX, and on Cursor’s in-house Composer model, the one SpaceX’s compute was supposed to accelerate in the first place. OpenAI framed the November deadline as maximum notice under its contract, and said it wants to “go above and beyond” to help developers through the transition. Whether Anthropic makes the same call is now the open question in AI coding.
The in-car Tesla Theater is among the most unique features available within the cars. When charging, parked, camping, or just hanging out, vehicle occupants can access a variety of streaming platforms on the large center screen, helping keep them entertained during downtime.
However, the Theater might be getting plenty more streaming platforms, something that owners have requested for some time.
Tesla owners recently discovered that visiting Apple TV in the vehicle browser can launch a fullscreen interface that looks and behaves like a dedicated application rather than an ordinary webpage:
Today I learned that if you go to Apple TV in the Tesla browser, it will open up an actual Apple TV app, fully functional. Not just the site.
Apparently there are more apps than just the few that show on the apps page. pic.twitter.com/os1Ypfm4JR

The experience drops the usual address bar and browser chrome, presenting catalogs, continue watching rows, and playback controls in the same window Tesla Theater already uses for its listed services. Independent testers soon found similar treatment for HBO Max, Paramount+, Peacock, Disney+, and Prime Video when those sites are opened from the car browser.
This shift is a plausible early signal that Tesla is widening Theater support without a formal software note. Theater has long been a set of web views rather than native applications, so recognizing extra domains and stripping the browser frame is a small server-side change that can expand the catalog quickly.
Owners still lack permanent Theater icons for the newly recognized services, and video remains limited to Park, yet the smoother launch is a meaningful step toward a broader lounge while charging.
Tesla Theater arrived with software version 10 in September 2019. The first video services were Netflix, YouTube, and Hulu, available only while parked and originally tied to WiFi. Spotify arrived in the same era as music rather than Theater video. Disney+ joined officially in July 2021 with the 2021.24 update, giving owners another major catalog on the center screen. Twitch and TikTok later appeared among the default Theater tiles, and Tesla Tutorials remained a persistent educational tile.
Not every addition stayed put. In December 2023, a Holiday software build removed the Disney+ tile for many United States owners after a public dispute involving advertising on X. Hulu stayed visible even though Disney owned it. Visiting disneyplus.com in the browser often restored the tile, which suggested the removal was a recognition list change rather than a complete block. Owners have also reported occasional blank Theater grids after updates, usually fixed by language toggles, resets, or later firmware.
Tesla axes Disney+ from vehicles with Musk-Iger rivalry, but there’s a workaround
Code archives from 2024 listed many unused source names, including Apple TV and Prime Video, that never became official icons, which now looks like groundwork for the current fullscreen browser behavior.
Now that this hint toward an expanded Theater experience has been recognized, Tesla could follow through with these additional shortcuts as a sign that more streaming platforms are available in Teslas than ever before.
Tesla recently received its largest order for the all-electric Semi from Einride, a Swedish transport service, for 500 units, a groundbreaking invoice to receive before the first deliveries begin.
Even more remarkable, Einride CEO Roozbeh Charli said in a recent interview that he expects his company to take delivery of all 500 — the entire order — before the end of 2027. He even expects to have 75 Tesla Semi units in the Einride fleet before the end of this year.

Charli said the Tesla partnership was part of a broader push, along with its earlier partnership with Amazon. Einride is assisting Amazon with the use of its Saga AI platform, which helps eliminate questions about budgeting and forecasting for logistics companies.
The Semi, as well as Tesla’s production and subsequent delivery of the units to Einride, will help the company “to have a good supply of vehicles that we can deploy on the [Saga AI] platform,” Charli said. “Tesla is also a relationship we’ve had for a while, and as the Tesla Semi deliveries are firming up, we decided to do a larger commitment to that and deploy that on our platform.”
In its initial announcement, Einride said it anticipated taking delivery of the trucks over the next two years, but now it appears the company is expecting all 500 units within the next 16 months.
Built at a dedicated factory in Sparks, Nevada, the Tesla Semi has been perhaps the biggest and most intensive testing process the company has ever had for a single vehicle model. For the past several years, Tesla has been working with many companies, most notably Frito-Lay and PepsiCo, to gain knowledge on the performance on regional routes.
Tesla plans to launch the Semi officially on September 24, five months after production started ramping.
Additionally, drivers have said they are happy about the Semi’s performance and that its numerous safety and productivity features have made their jobs and routes much easier.
