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 is advancing a fully automated pipeline for the 4680 battery cells used in its all-electric Semi, spanning production from Giga Texas through shipment and direct consumption on the line at the new dedicated Semi Factory in Sparks, Nevada.
The approach was outlined by Tesla at its September 24 Semi Handover event, which launched high-volume production at its new 1.8-million-square-foot plant in Nevada, which sits adjacent to Gigafactory Nevada and is designed for an annual production rate of 50,000 trucks per year.
After years of pilot builds and what was a four-year-long redesign of the truck, Tesla moved the Semi from 2170 batteries to its in-house 4680 cells, which are made in Austin. The change cuts battery mass and total energy while holding range, a key step in making volume production a realistic possibility.
Cells will leave Giga Texas in trailers, and at the Nevada Semi plant, Tesla intends for a dedicated line to unload those trailers automatically, station the cells, and feed them straight into pack and vehicle assembly.

Both Lars Moravy, Tesla’s VP of Vehicle Engineering, and Dan Priestley, the Head of Tesla’s Semi program, described the goal as a “zero human touch point” from the moment the trailer arrives in Texas until a finished Semi drives off the production line in Nevada.
The unloading system that Moravy and Priestley described is just one piece of a much broader automation push. The plant uses what Tesla calls the highest-capacity electric monorail conveyance in vehicle manufacturing, carrying frames-in-white simultaneously. Powder-coating replaces conventional paint, and many processes that would normally require operators have been designed out.
Tesla has repeatedly said that “the best part is no part,” and the cell-handling plan extends that philosophy from the cell factory floor in Texas all the way to final assembly in Nevada.
If executed as described, the closed-loop flow would reduce labor, handling damage, and inventory buffers while tightening quality control on a component that represents a large share of the truck’s cost and weight. It also shortens the physical and organizational distance between two factories separated by more than 1,200 miles. The Semi itself now shares a bar-wound stator and other components with the Cybertruck, further linking Tesla’s passenger and commercial production systems.
High-volume output is expected to ramp gradually after the first trucks left the new line in April 2026. Early customers include PepsiCo, DHL, and U.S. Foods. Whether the automated trailer-to-line process reaches the promised zero-touch standard will be visible in the coming months as production scales. For Tesla, the Semi factory is another test of how far it can push “the machine that builds the machine” across sites.

Elon Musk’s AI Grok Bot can now handle banking while your Tesla FSD handles the road
Elon Musk says Grok Bot can manage your finances through linked bank and investment accounts.
Grok Bot now wants access to your wallet, with SpaceXAI rolling out a new Finance integration for its agent platform that lets users link bank, credit card and investment accounts thereby letting their Bots help manage spending, investments and more. Elon Musk amplified the announcement on X with a short endorsement, “Grok Bot can manage your finances.”
The feature builds on two earlier steps. In early September, Grok gained the ability to answer questions about spending, savings, investments and cash flow using accounts connected through Plaid, starting with users in the U.S. Before that, on August 28, SpaceXAI let Grok Bot buy things online through Link, with users approving every spend request and the Bot receiving a single use card for each payment.
Musk has already shown how far he wants users to push it. In late August, when Tesla investor account Teslaconomics said he was weighing whether to give Grok Bot access to his bank accounts, Musk replied, “Try it out. If Grok Bot messes up, we will make you whole.” That promise goes beyond SpaceXAI’s consumer terms, which make users responsible for what their agents do and generally cap the company’s liability at the greater of fees paid or $100. SpaceXAI’s own documentation recommends requiring approval for purchases and financial transfers.
For Tesla owners, the update lands five days after Tesla brought Grok Bot into its vehicles, letting drivers hand off errands by voice while FSD (Supervised) handles the road. Bot access inside the car is currently limited to SuperGrok Heavy subscribers, though Connectors are open to anyone signed into Grok. With Finance linked, a driver could ask for a spending summary or a check on upcoming bills during the commute.
Grok’s role in the car has grown quickly since Tesla’s Summer Update let it control cabin features by voice. We have been using Grok Bot in our own Tesla for several weeks, and here’s how our latest test went.

SpaceX just got the green light Starship has waited years for
The FAA has cleared Starship Flight 14, setting up SpaceX’s first orbital attempt on Monday.
SpaceX has cleared the last regulatory hurdle standing between Starship and its first trip to orbit. The Federal Aviation Administration issued the launch license for Starship Flight 14 late Saturday, keeping the mission on track for liftoff Monday, September 28, from Pad 2 at Starbase, Texas.
The 75 minute launch window opens at 7:15 a.m. Central, and Boca Chica Beach closures are also scheduled for September 29 and 30 as backup dates. This will be Starship’s first revenue generating mission.
The license was the missing piece after SpaceX completed a full wet dress rehearsal with Booster 21 and Ship 41 on September 24. At the time, the company said the flight remained on track pending regulatory approval. Because Flight 14 flies an orbital profile, the FAA had to sign off on a modified license that met its safety, payload and financial responsibility requirements.
Observers combing through the new FAA paperwork also noticed that lightning no longer appears among Starship’s listed launch hazards. If that holds, it matters more for where Starship is headed than for Monday’s attempt. Florida and Louisiana, home to LC-39A and the planned Starbase Louisiana site, see some of the most frequent lightning in the United States.
SpaceX tells the FCC that Starship Flight 14 is going to orbit
Flight 14 is the mission SpaceX has been building toward for months. Ship 41 will carry 26 Starlink V3 satellites, the first operational V3 units to be deployed, and attempt roughly six orbits at about 275 kilometers over a flight lasting just under 10 hours. SpaceX says the ship will only perform its orbital insertion burn after flight controllers confirm enough hardware redundancy remains for the deorbit burn at the end of the mission. Ship 41 is targeting a splashdown in the Pacific west of Chile, while Super Heavy will return to the Gulf of Mexico.
The date carries some symbolism as well. A Monday launch would come 10 years and one day after Elon Musk first presented the Interplanetary Transport System, the design that became Starship, at the International Astronautical Congress in Guadalajara, Mexico.
SpaceX has not announced what comes next, but air traffic planning slides reported this week, list Flight 15 no earlier than October 19 and a first Starship launch from LC-39A in Florida no earlier than October 30. Both dates depend on how Monday goes.
