Tesla China supplier CATL launches cost-effective sodium-ion battery cell
Tesla China battery cell supplier Contemporary Amperex Technology Co. Ltd. (CATL) unveiled its sodium-ion battery earlier today, along with a solution that could integrate the cells with lithium-ion batteries in a single pack. The sodium-ion cells are a more cost-effective option than the lithium-ion batteries, opening the door for lower prices in the EV battleground market of China.
The introduction of sodium-ion cells is an alternative option to the lithium-ion cells Tesla has used in its vehicles. CATL Chairman Zeng Yuqun highlighted the favorable characteristics of utilizing sodium-ion cells during the company’s online launch event earlier today.
“Sodium-ion batteries have unique advantages in low-temperature performance, fast charging, and environmental adaptability,” Zeng said. “Moreover, they’re compatible and complementary with lithium-ion batteries. Diversified technical routes are an important guarantee for the long-term development of the industry.”
CATL said it will set up a supply chain for the new cells in 2023. The cells do not contain lithium, cobalt, or nickel, but the battery manufacturer did not disclose any cost details of the new cell.
Tesla has long been working with suppliers for battery cells and has partnerships with Panasonic, LG Chem, and CATL to supply its electric vehicles with batteries. While working with third-party suppliers, the company has also researched on its own with the help of a battery team at Dalhousie University with legendary cell scientist Jeff Dahn. Tesla is not opposed to exploring battery cell chemistries favorable for electric vehicles, especially if the new cells can create more range, power, or a longer life cycle.
CATL has worked with Tesla since Gigafactory Shanghai started producing vehicles in late 2019. Tesla started customer deliveries in early 2020 at the Chinese plant and has relied on CATL’s world-class battery manufacturing to keep up with growing demand in China. CATL sold 34.1 GWh in the first half of 2021, up 234% year-over-year, according to Automotive News China. The company has a 30 percent market share, but the company has been struggling with the rising cost of lithium carbonate, which has doubled this year. Additionally, nickel has also increased in price this year.
Due to increased demand, lithium prices are expected to trend higher this year and into next year, especially as more automakers extend into the electric automotive sector. These forecasts have launched battery makers like CATL into a widespread effort to experiment and develop other cell chemistries that would be favorable for their clients, and sodium-ion batteries are a great alternative.
Despite the sodium-ion cell’s reputation for somewhat lower energy density, CATL said that its Research and Development team had reached an energy density of 160 watt-hours per kilogram, and it should exceed 200 Wh/kg in the coming years as more experimentation continues. For comparison, lithium-ion cells can reach about 285 Wh/kg, according to K. M. Abraham, a research professor at Northeastern University. Interestingly, the solution CATL also unveiled at the event is also expected to compensate for the reduced energy density of the sodium-ion cell, while preserving the advantage the cell makeup has to offer.
News of the new cell shot Tesla stock up over 4.6% in early trading hours on Thursday. At the time of writing, TSLA stock traded at $677.07, up $30.23.

Tesla reveals it is using AI to make factories more sustainable: here’s how
Tesla is using AI in its Gigafactory Nevada factory to improve HVAC efficiency.

Tesla has revealed in its Extended Impact Report for 2024 that it is using Artificial Intelligence (AI) to enable its factories to be more sustainable. One example it used was its achievement of managing “the majority of the HVAC infrastructure at Gigafactory Nevada is now AI-controlled” last year.
In a commitment to becoming more efficient and making its production as eco-friendly as possible, Tesla has been working for years to find solutions to reduce energy consumption in its factories.
For example, in 2023, Tesla implemented optimization controls in the plastics and paint shops located at Gigafactory Texas, which increased the efficiency of natural gas consumption. Tesla plans to phase out natural gas use across its factories eventually, but for now, it prioritizes work to reduce emissions from that energy source specifically.
It also uses Hygrometric Control Logic for Air Handling Units at Giafactory Berlin, resulting in 17,000 MWh in energy savings each year. At Gigafactory Nevada, Tesla saves 9.5 GWh of energy through the use of N-Methylpyrrolidone refineries when extracting critical raw material.
Perhaps the most interesting way Tesla is conserving energy is through the use of AI at Gigafactory Nevada, as it describes its use of AI to reduce energy demand:
“In 2023, AI Control for HVAC was expanded from Nevada and Texas to now include our Berlin-Brandenburg and Fremont factories. AI Control policy enables HVAC systems within each factory to work together to process sensor data, model factory dynamics, and apply control actions that safely minimize the energy required to support production. In 2024, this system achieved two milestones: the majority of HVAC infrastructure at Gigafactory Nevada is now AI-controlled, reducing fan and thermal energy demand; and the AI algorithm was extended to manage entire chiller plants, creating a closed-loop control system that optimizes both chilled water consumption and the energy required for its generation, all while maintaining factory conditions.”
Tesla utilizes AI Control “primarily on systems that heat or cool critical factory production spaces and equipment.” AI Control communicates with the preexisting standard control logic of each system, and any issues can be resolved by quickly reverting back to standard control. There were none in 2024.
Tesla says that it is utilizing AI to drive impact at its factories, and it has proven to be a valuable tool in reducing energy consumption at one of its facilities.

Tesla analysts believe Musk and Trump feud will pass
Tesla CEO Elon Musk and U.S. President Donald Trump’s feud shall pass, several bulls say.

Tesla analysts are breaking down the current feud between CEO Elon Musk and U.S. President Donald Trump, as the two continue to disagree on the “Big Beautiful Bill” and its impact on the country’s national debt.
Musk, who headed the Department of Government Efficiency (DOGE) under the Trump Administration, left his post in May. Soon thereafter, he and President Trump entered a very public and verbal disagreement, where things turned sour. They reconciled to an extent, and things seemed to be in the past.
However, the second disagreement between the two started on Monday, as Musk continued to push back on the “Big Beautiful Bill” that the Trump administration is attempting to sign into law. It would, by Musk’s estimation, increase spending and reverse the work DOGE did to trim the deficit.
Every member of Congress who campaigned on reducing government spending and then immediately voted for the biggest debt increase in history should hang their head in shame!
And they will lose their primary next year if it is the last thing I do on this Earth.

President Trump has hinted that DOGE could be “the monster” that “eats Elon,” threatening to end the subsidies that SpaceX and Tesla receive. Musk has not been opposed to ending government subsidies for companies, including his own, as long as they are all abolished.
How Tesla could benefit from the ‘Big Beautiful Bill’ that axes EV subsidies
Despite this contentious back-and-forth between the two, analysts are sharing their opinions now, and a few of the more bullish Tesla observers are convinced that this feud will pass, Trump and Musk will resolve their differences as they have before, and things will return to normal.
ARK Invest’s Cathie Wood said this morning that the feud between Musk and Trump is another example of “this too shall pass:”

Additionally, Wedbush’s Dan Ives, in a note to investors this morning, said that the situation “will settle:”
“We believe this situation will settle and at the end of the day Musk needs Trump and Trump needs Musk given the AI Arms Race going on between the US and China. The jabs between Musk and Trump will continue as the Budget rolls through Congress but Tesla investors want Musk to focus on driving Tesla and stop this political angle…which has turned into a life of its own in a roller coaster ride since the November elections.”
Tesla shares are down about 5 percent at 3:10 p.m. on the East Coast.

Tesla scrambles after Musk sidekick exit, CEO takes over sales
Tesla CEO Elon Musk is reportedly overseeing sales in North America and Europe, Bloomberg reports.

Tesla scrambled its executives around following the exit of CEO Elon Musk’s sidekick last week, Omead Afshar. Afshar was relieved of his duties as Head of Sales for both North America and Europe.
Bloomberg is reporting that Musk is now overseeing both regions for sales, according to sources familiar with the matter. Afshar left the company last week, likely due to slow sales in both markets, ending a seven-year term with the electric automaker.
Tesla’s Omead Afshar, known as Elon Musk’s right-hand man, leaves company: reports
Afshar was promoted to the role late last year as Musk was becoming more involved in the road to the White House with President Donald Trump.
Afshar, whose LinkedIn account stated he was working within the “Office of the CEO,” was known as Musk’s right-hand man for years.
Additionally, Tom Zhu, currently the Senior Vice President of Automotive at Tesla, will oversee sales in Asia, according to the report.
It is a scramble by Tesla to get the company’s proven executives over the pain points the automaker has found halfway through the year. Sales are looking to be close to the 1.8 million vehicles the company delivered in both of the past two years.
Tesla is pivoting to pay more attention to the struggling automotive sales that it has felt over the past six months. Although it is still performing well and is the best-selling EV maker by a long way, it is struggling to find growth despite redesigning its vehicles and launching new tech and improvements within them.
The company is also looking to focus more on its deployment of autonomous tech, especially as it recently launched its Robotaxi platform in Austin just over a week ago.
However, while this is the long-term catalyst for Tesla, sales still need some work, and it appears the company’s strategy is to put its biggest guns on its biggest problems.
