Tesla explores safer battery production with novel DCM recovery system patent
In what appears to be yet another step towards its goal of operating the safest car factory in the industry, Tesla has been granted a patent that could pave the way for a safer process in battery production. Published today, the electric car maker’s recent patent describes a system to treat and recycle Dichloromethane (DCM), which is among the materials used in the production of electric car batteries.
DCM is utilized in a variety of industrial processes, particularly in chemical plastic welding, wherein softened plastic pieces or surfaces are welded together. The material is also used to soften plastic sheets for stretching or shaping, and as a solvent to remove unwanted compounds. In Tesla’s case, DCM is among the materials used in the forming of a separator base film for an electric car’s battery system. While DCM is invaluable in manufacturing, though, the material carries some health risks.
Dichloromethane is the least toxic among the simple chlorohydrocarbons, but its high volatility makes it an inhalation hazard nonetheless. Prolonged skin contact with DCM could also result in the material dissolving some of the skin’s fatty tissues, causing irritation or chemical burns. With these risks in mind, the manufacturing industry employs ways to recover DCM. Tesla notes that current systems for DCM treatment and recovery are capital intensive, particularly since the process involves expensive components such as activated carbon beds, condensers, steam boilers and distribution systems, density separation vessels, and waste water treatment systems.

Tesla describes conventional DCM treatment systems as follows:
“The DCM itself may then be removed through a heating and/or evaporation process with the exhaust collected. This exhaust containing DCM is then combined with the exhaust from other tools and systems used in the manufacturing process. The combined exhaust may then be fed to a recovery plant to recover DCM. In the recovery plant, the waste exhaust stream is typically treated with activated carbon. This scrubbing process requires high capital expenditure (many expensive components), high operating cost (extensive steam and cooling water consumption which accounts for >20% of total process cost), large footprint requirements, and large amounts of waste water that need to be processed. In order to address these cost and environmental-remediation issues, an improved process for the removal of DCM from exhaust streams is needed.”
Tesla’s take on DCM treatment and recovery utilizes a wet scrubber and a density separator vessel as key components of the system. The wet scrubber in Tesla’s patent has a scrubbing chamber, where water is utilized to scrub the waste exhaust stream containing the DCM. Tesla notes that the wet scrubber could adopt a variety of designs to remove DCM from the waste exhaust stream, including a venturi scrubber design, a condensation scrubber design, an impingement-plate scrubber design, or a packed bed tower design, among others.
Tesla’s use of a density separator vessel is described in the following section from the patent.
“The density separator vessel has an inlet to receive the liquid water and DCM mixture, an outlet to expel DCM, and an outlet to expel waste water. The DCM may be routed back to the industrial process for reuse and/or collected for later use. The waste water may be routed back to the wet scrubber, as shown along (the) waste water return loop. Waste water may also or alternately be routed to waste water treatment system for processing for subsequent treatment by (the) waste water treatment system.
“Typically, a large portion of the waste water is returned to the wet scrubber via (the) waste water return loop and a small portion of the waste water is treated by the waste water treatment system. Even though the waste water may contain small amounts of DCM, the waste water will still retain its ability to scrub the exhaust containing DCM. An advantage of the wet scrubber over the activated carbon beds is that all or most of the water used by the wet scrubber is the waste water from the density separator vessel, resulting in substantial savings of water and energy, and resultantly, substantial cost savings.”
Tesla states that compared to more traditional exhaust treatment systems, the DCM treatment and recovery model outlined in its patent effectively eliminates the use of steam and cooling, while also reducing the amount of throughput needed by a waste water system. With these efficiencies in mind, Tesla notes that it could reduce capital expenditures and operating costs “for the same amount of DCM processed processing.” The increased simplicity of the system and reduced airflow rates are expected to help the company get more savings in both capital expenditures and operating costs as well.
More than a way to optimize its operations, Tesla’s recent patent is also a notable way for the company to keep its battery production lines safer for its employees. Such a system would definitely be invaluable for the company, particularly as Tesla is now preparing the Model 3 for a global rollout. With the Model 3 ramp ever-expanding, and with high-volume vehicles like the Model Y and possibly the Tesla pickup truck in the pipeline, optimizations such as a better DCM treatment and recovery system are all but necessary.

Tesla tailwinds could drive momentum-filled finish to 2025: analyst
Tesla is heading toward some momentum to finish out the year, one Wall Street firm believes.
Tesla has some tailwinds that could drive it toward a momentum-filled finish to the year, one Wall Street analyst is predicting.
The tailwinds are joined by some minor risks that have impacted the broader electric vehicle market, but overall, this firm believes Tesla has many catalysts moving forward.
Emmanuel Rosner of Wolfe Research believes that Tesla has plenty of things that could drive the stock upward as we approach the end of the year. With Q3 well underway, Tesla has about five months of catalysts to rely on to erase the roughly 18 percent drop in stock price it has so far this year.
At first glance, it is easy to see the things that would have investors bullish on Tesla for the rest of 2025 and even beyond. Initially, the Robotaxi launch and expansion, which spread to Northern California last night, provide potentially huge tailwinds for the company moving forward.
Along with that, and slightly related, are the advancements in Full Self-Driving that the company has made over the past few months.
This includes the potential launch of the FSD suite in regions like Europe and Australia, where the company believes it will make some progress on regulatory approval in the coming months.
Finally, Wolfe says the company’s Optimus project, which is expected to enter scale production sometime next year, is the third catalyst for Tesla moving forward.
With these three projects in motion, Tesla truly can begin to work on rebounding from a rough 2025 on the market.
Rosner writes:
“This name trades more around the narrative than the numbers. And net-net, we tactically see an improving narrative from here. Tesla has several catalysts coming up w/r/t FSD and Robotaxi, including an expansion of their AV service into several new U.S. markets (San Francisco, Nevada, Arizona, Florida, etc.). The company plans to unlock hands-free/eyes-off autonomy for FSD owners in select U.S. locations by YE25. Supervised FSD in China and Europe is expected to launch over the next ~12 months. And, Optimus is expected to enter scale production in 2026.”
Tesla is currently trading around $310 at around 3:20 p.m. on the East Coast.

Tesla Robotaxi execution should lead to valuation ‘far exceeding current levels’: analyst
RBC Capital bumped its price target on Tesla stock slightly from $319 to $325.
Tesla’s Robotaxi platform is the primary focus for the automaker currently, and based on what has been outlined by the company as goals for the project, one firm is saying that the company’s valuation should “far exceed even current levels.”
The Robotaxi is a self-driving ride-hailing service that Tesla plans to implement in current and future vehicle builds. CEO Elon Musk and other executives have said that “the vast majority of the Tesla fleet that we’ve made is capable of being a Robotaxi,” thanks to its development of Over-the-Air software updates that increase the capability of the vehicle with a simple download.
Currently, the Robotaxi platform is only active in a portion of Austin, Texas, but Tesla is expanding to other markets, including California, Nevada, Arizona, and Florida. California will be the next market to open its doors to the Tesla Robotaxi platform.

But the name of the game is execution, and that’s what Tesla is aiming for in a timely fashion. If it can come through on all of its current goals, its valuation could explode, and one firm is holding steady on that narrative as Tesla continues to work toward expanding Robotaxi.
On Tuesday, RBC Capital analysts bumped their price target on Tesla shares (NASDAQ: TSLA) to $325 from $319, primarily due to the Robotaxi expansion and its success:
“Should Tesla be successful on all of its goals, its valuation could far exceed even current levels. The Austin Robotaxi launch has been better than many feared, and the company is looking to expand in more cities.”
There are some risks to Tesla’s narrative, but they fall outside the scope of what the company can control. In relation to Robotaxi, regulatory hurdles remain. Some regions may be slower than others to give Tesla the proper licensing to operate in their jurisdiction. This could slow the pace of Robotaxi expansion, bringing some overhang to the story.
Additionally, Tesla is fending off narratives of slowing demand, and the White House’s decision to revoke the $7,500 EV tax credit from consumers could temper sales past Q3.
Nevertheless, Robotaxi is where Tesla’s true value seems to be focused. Successfully launching a driverless ride-sharing platform is where the company is putting all of its eggs, and revolutionizing passenger travel is where the focus lies.
RBC Capital’s note continued:
“Regulatory hurdles remain, however. Further, we expect the end of IRA credits and high levels of used EV inventory to pressure the auto business for the next several quarters.”
The slight price target bump puts RBC Capital’s expectations near where the stock is trading, as it is currently priced at around $320 at 9:54 a.m. on the East Coast.

Elon Musk shares details on Tesla AI6 production deal with Samsung
Tesla is already laying the groundwork for the ramp of its next-generation products.
Elon Musk has provided some details about Tesla’s AI6 production deal with South Korean tech giant Samsung. As per Musk, Samsung’s upcoming Texas fabrication facility will be dedicated to the production of Tesla’s AI6 chip.
Musk’s update suggests that Tesla is already laying the groundwork for the ramp of its next-generation products like the Cybercab and Optimus.
Samsung AI6 production reports
On Sunday, Bloomberg News claimed that Samsung will be producing semiconductors for Tesla in a $16.5 billion deal. As per the report, Samsung is currently producing Tesla’s AI4 chip, and the deal will help the South Korean tech giant gain some ground back from competitors in the semiconductor market.
Elon Musk confirmed the news on X, stating that the $16.5 billion is actually just the bare minimum. As per Musk, the deal with Samsung will likely be “much more than that.” And in a later comment, Musk clarified that the actual output of Samsung’s Tesla AI6 plant will “likely be several times higher” than what has been reported.
Musk shared a critical detail that would likely allow Samsung to maximize its AI6 output. “Samsung agreed to allow Tesla to assist in maximizing manufacturing efficiency. This is a critical point, as I will walk the line personally to accelerate the pace of progress. And the fab is conveniently located not far from my house,” Musk wrote in his post.
Elon Musk on AI5 and AI6
Tesla currently produces vehicles with its AI4 chip, which is produced by Samsung. As per the CEO, Tesla’s AI5 chip, which just finished its design, will be produced by TSMC. The AI5 chip will be produced initially in Taiwan, and then in Arizona, the CEO noted.
Elon Musk’s comments about AI6 and Samsung’s output suggest that Tesla is really preparing to enter a stage in its growth that involves production at a scale that’s never been seen before. Tesla’s speed is quite notable, though it seems safe to assume that the actual rollout of AI6 will still be a few years away.
In a few years, Tesla will probably be mass producing the Cybercab and Optimus, as well as more affordable vehicles that will likely see more adoption from mainstream customers. This means that Samsung’s AI6 ramp will likely be just in time to support Tesla’s outputs for its Optimus bots, its Cybercabs, and its mass market affordable cars.
