Tesla’s zero-cobalt battery goes beyond price parity, it’s a strike to gas cars’ jugular
It is no secret that Tesla is pursuing a million-mile battery. This battery will be so advanced, it would be able to stand the most stressful conditions for electric vehicles without compromising its quality and longevity; and when used for energy storage devices, it could last decades with regular use. If recent reports are any indication, it appears that Tesla’s million-mile battery could very well be the factor that would allow sustainable transportation to go for fossil fuels’ jugular.
One key factor that is still blocking the electric vehicle movement is the price of batteries. For the longest time, it has been widely speculated that reducing battery production costs to $100/kWh is the key to EVs reaching price parity with their petrol-powered counterparts. A recent report from Reuters, citing individuals familiar with Tesla’s battery efforts, has noted that the cost of Tesla’s batteries could fall even lower than $100/kWh.
Tesla is reportedly poised to start using batteries that it developed with China’s Contemporary Amperex Technology Ltd. (CATL) in the near future, with some reports speculating that the new cells could be rolled out to the Made-in-China Model 3 later this year. This battery, which will be cobalt-free, is reportedly a solid step towards a full rollout of Tesla’s million-mile battery. These batteries are still set to be improved as well, with the cells’ energy density and storage capacity being optimized over time.
Estimates indicate that CATL’s cobalt-free lithium iron phosphate battery packs for Tesla have fallen to $80/kWh, with the cost of the battery cells themselves dropping to about $60/kWh. Provided that these estimates are accurate, Tesla’s electric cars will not only be able to meet the $100/kWh target and meet price parity with gas powered cars, the company’s vehicles could actually become cheaper than their petrol-powered counterparts in the future.
Battery expert Shirley Meng, a professor at the University of California San Diego, noted that these costs, even for more expensive NMC cells, would drop even further when battery recycling comes into the picture. Fortunately for Tesla, there are signs that a serious effort to recycle batteries is underway. Reports indicate that the electric car maker is working steadily to recycle and recover key materials in its batteries, such as nickel, cobalt, and lithium.
Tesla’s efforts at recycling its batteries have been known for some time, considering the company’s focus on sustainability. These efforts are being pushed through Redwood Materials, a firm that’s focused on recovering vital battery components. Interestingly enough, Redwood Materials is headed by JB Straubel, a co-founder and longtime Chief Technology Officer of Tesla. Straubel is an authority in batteries, as evidenced by the fact that Elon Musk was already sponsoring his battery research even before both of them joined Tesla.
If Tesla can master battery recycling, and if it can reduce its battery costs to $80/kWh and below, the company’s electric vehicles could become even more competitive in the auto market. As it is, Teslas are still quite expensive compared to their gas-powered counterparts due to their batteries’ costs, and yet, some of the company’s vehicles like the Model 3 are already dominating established gas-powered cars like the BMW M3 on the market. One can only imagine how far Tesla could go with a vehicle like the Model Y, which caters to the hyper-popular crossover market, and a million-mile battery whose costs are down to less than $100/kWh.
With Teslas reaching or even exceeding price parity with gas powered rivals, there will be very little incentive for car buyers to purchase petrol-powered cars over electric vehicles. Premium EVs, after all, are cheaper to run, more powerful, and far cleaner. The million-mile battery may only be one of the things that Tesla is working on to optimize its vehicles, but it goes a long way towards the company’s fight for sustainability.

Tesla AI5 chip nears completion, Elon Musk teases 9-month development cadence
The Tesla CEO shared his recent insights in a post on social media platform X.
Tesla’s next-generation AI5 chip is nearly complete, and work on its successor is already underway, as per a recent update from Elon Musk.
The Tesla CEO shared his recent insights in a post on social media platform X.
Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.
This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.

Tesla Sweden uses Megapack battery to bypass unions’ Supercharger blockade
Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery.
Tesla Sweden has successfully launched a new Supercharger station despite an ongoing blockade by Swedish unions, using on-site Megapack batteries instead of traditional grid connections. The workaround has allowed the Supercharger to operate without direct access to Sweden’s electricity network, which has been effectively frozen by labor action.
Tesla has experienced notable challenges connecting its new charging stations to Sweden’s power grid due to industrial action led by Seko, a major Swedish trade union, which has blocked all new electrical connections for new Superchargers. On paper, this made the opening of new Supercharger sites almost impossible.
Despite the blockade, Tesla has continued to bring stations online. In Malmö and Södertälje, new Supercharger locations opened after grid operators E.ON and Telge Nät activated the sites. The operators later stated that the connections had been made in error.
More recently, however, Tesla adopted a different strategy altogether. Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery, as noted in a Dagens Arbete (DA) report.
Because the Supercharger station does not rely on a permanent grid connection, Tesla was able to bypass the blocked application process, as noted by Swedish car journalist and YouTuber Peter Esse. He noted that the Arlandastad Supercharger is likely dependent on nearby companies to recharge the batteries, likely through private arrangements.
Eight new charging stalls have been launched in the Arlandastad site so far, which is a fraction of the originally planned 40 chargers for the location. Still, the fact that Tesla Sweden was able to work around the unions’ efforts once more is impressive, especially since Superchargers are used even by non-Tesla EVs.
Esse noted that Tesla’s Megapack workaround is not as easily replicated in other locations. Arlandastad is unique because neighboring operators already have access to grid power, making it possible for Tesla to source electricity indirectly. Still, Esse noted that the unions’ blockades have not affected sales as much.
“Many want Tesla to lose sales due to the union blockades. But you have to remember that sales are falling from 2024, when Tesla sold a record number of cars in Sweden. That year, the unions also had blockades against Tesla. So for Tesla as a charging operator, it is devastating. But for Tesla as a car company, it does not matter in terms of sales volumes. People charge their cars where there is an opportunity, usually at home,” Esse noted.
