Tesla Made-in-China Model 3 locks in approval for cobalt-free battery use
Tesla has officially received approval from the Chinese Ministry of Industry and Information Technology to use lithium iron phosphate batteries for its locally-made Model 3 sedan.
Lithium iron phosphate batteries, often identified by the acronym LFP, lack any cobalt in their composition. Cobalt, while an efficient and crucial element to previous builds of lithium-ion batteries, is controversial because a number of mines’ questionable practices.
Because of cobalt’s questionable roots, Tesla has focused on using batteries that utilize less and less of the metal. Instead, the company has been in advanced talks with CATL, its Chinese battery supplier, since February. It is unknown if CATL will be supplying Tesla with the batteries for the Made-in-China Model 3, according to Reuters, but the two companies do have a two-year contract that took effect earlier this month.
Removing cobalt has been a primary focus of Tesla’s battery development for a while now. In Tesla’s 2019 Impact Report, which was released on June 8, 2020, the automaker described its current practices for mining Cobalt and outlined how its current batteries use less of the metal than other assemblies.
“Tesla’s batteries use nickel-rich cathode materials which contain less cobalt than other widely use cathode chemistries in the industry with our ultimate goal being to eliminate cobalt completely from our cells,” Tesla stated in its Impact Report.
Tesla maintains a strict due diligence policy for its acquisition of cobalt. Each of its cobalt suppliers and partners must uphold responsible and integrity-focused techniques when acquiring the metal.
“Tesla is committed to making working conditions in our supply chain safe and humane, ensuring that workers are treated with respect and dignity, and that manufacturing processes are environmentally responsible,” the company also wrote in its Impact Report.
The company did mention in the report that the eventual goal was to entirely phase out the use of cobalt within its batteries, but developments must be made. Cobalt is a crucial part of a vehicle’s electric battery because it stabilizes the power cycle and supplies the pack with high-rate performance, ScienceMag reported. Cobalt, when decreased in an EV battery, must be replaced with nickel.
However, high amounts of nickel can lead to overheating and could cause the batteries to combust. This reaction would create a dangerous environment for a driver and those surrounding the vehicle.
Tesla’s introduction of cobalt-free batteries into its Made-in-China Model 3 could be just the beginning. The company mentioned in its Impact Report that it would eventually rid cobalt from its cells, and China is just the start. Eventually, all Tesla cars will be manufactured without the expensive metal, which could ultimately lead to lower vehicle prices.
Tesla made a change to the Cybertruck, and nobody noticed. But to be fair, nobody could have, but it was revealed by the program’s lead engineer that it was aimed toward simplifying manufacturing through a minor change in casting.
After the Cybertruck was given a Top Safety Pick+ award by the Insurance Institute for Highway Safety (IIHS), for its reputation as the safest pickup on the market, some wondered what had changed about the vehicle.
Tesla makes changes to its vehicles routinely through Over-the-Air software updates, but aesthetic changes are relatively rare. Vehicles go through refreshes every few years, as the Model 3 and Model Y did earlier this year. However, the Cybertruck is one of the vehicles that has not changed much since its launch in late 2023, but it has gone through some minor changes.
Most recently, Wes Morrill, the Cybertruck program’s Lead Engineer, stated that the company had made a minor change to the casting of the all-electric pickup for manufacturing purposes. This change took place in April:
We made a minor change on the casting for manufacturability in April. Our Internal testing shows no difference in crash result but IIHS only officially tested the latest version

The change is among the most subtle that can be made, but it makes a massive difference in manufacturing efficiency, build quality, and scalability.
Morrill revealed Tesla’s internal testing showed no difference in crash testing results performed by the IIHS.
The 2025 Cybertruck received stellar ratings in each of the required testing scenarios and categories. The Top Safety Pick+ award is only given if it excels in rigorous crash tests. This requires ‘Good’ ratings in updated small and moderate overlap front, side, roof, and head restraints.
Additionally, it must have advanced front crash prevention in both day and night. Most importantly, the vehicle must have a ‘Good’ or ‘Acceptable’ headlights standard on all trims, with the “+ ” specifically demanding the toughest new updated moderate overlap test that checks rear-seat passenger protection alongside driver safety.
Tesla has entered an interesting situation with its Full Self-Driving suite in California, as the State’s Department of Motor Vehicles had adopted an order for a suspension of the company’s sales license, but it immediately put it on hold.
The company has been granted a reprieve as the DMV is giving Tesla an opportunity to “remedy the situation.” After the suspension was recommended for 30 days as a penalty, the DMV said it would give Tesla 90 days to allow the company to come into compliance.
The DMV is accusing Tesla of misleading consumers by using words like Autopilot and Full Self-Driving on its advanced driver assistance (ADAS) features.
The State’s DMV Director, Steve Gordon, said that he hoped “Tesla will find a way to get these misleading statements corrected.” However, Tesla responded to the story on Tuesday, stating that this was a “consumer protection” order for the company using the term Autopilot.
It said “not one single customer came forward to say there’s a problem.” It added that “sales in California will continue uninterrupted.”
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 used the terms Autopilot and Full Self-Driving for years, but has added the term “(Supervised)” to the end of the FSD suite, hoping to remedy some of the potential issues that regulators in various areas might have with the labeling of the program.
It might not be too long before Tesla stops catching flak for using the Full Self-Driving name to describe its platform.
Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing
The Robotaxi suite has continued to improve, and this week, vehicles were spotted in Austin without any occupants. CEO Elon Musk would later confirm that Tesla had started testing driverless rides in Austin, hoping to launch rides without any supervision by the end of the year.
Tesla stock (NASDAQ: TSLA) closed at an all-time high on Tuesday, jumping over 3 percent during the day and finishing at $489.88.
The price beats the previous record close, which was $479.86.
Shares have had a crazy year, dipping more than 40 percent from the start of the year. The stock then started to recover once again around late April, when its price started to climb back up from the low $200 level.
This week, Tesla started to climb toward its highest levels ever, as it was revealed on Sunday that the company was testing driverless Robotaxis in Austin. The spike in value pushed the company’s valuation to $1.63 trillion.
Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing
It is the seventh-most valuable company on the market currently, trailing Nvidia, Apple, Alphabet (Google), Microsoft, Amazon, and Meta.
Shares closed up $14.57 today, up over 3 percent.
The stock has gone through a lot this year, as previously mentioned. Shares tumbled in Q1 due to CEO Elon Musk’s involvement with the Department of Government Efficiency (DOGE), which pulled his attention away from his companies and left a major overhang on their valuations.
However, things started to rebound halfway through the year, and as the government started to phase out the $7,500 tax credit, demand spiked as consumers tried to take advantage of it.
Q3 deliveries were the highest in company history, and Tesla responded to the loss of the tax credit with the launch of the Model 3 and Model Y Standard.
Additionally, analysts have announced high expectations this week for the company on Wall Street as Robotaxi continues to be the focus. With autonomy within Tesla’s sights, things are moving in the direction of Robotaxi being a major catalyst for growth on the Street in the coming year.
