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.

‘You chose ambition’: Tesla Chair hails shareholders for backing Elon Musk’s vision
Denholm stated that the vote highlighted TSLA investors’ continued confidence in both Musk’s leadership and Tesla’s vision for an autonomous, AI-driven future.
Tesla Chair Robyn Denholm has issued a letter to shareholders celebrating what she described as “overwhelming support” at this year’s Annual Meeting, framing the approval of Elon Musk’s trillion-dollar pay plan as a defining moment in Tesla’s mission.
Denholm stated that the vote highlighted TSLA investors’ continued confidence in both Musk’s leadership and Tesla’s vision for an autonomous, AI-driven future.
Denholm hails shareholder confidence
In her letter, which was posted by the electric vehicle maker on X through Tesla’s official handle, Denholm thanked investors for backing Proposals One, Three, and Four, items she said reaffirm Tesla’s “Master Plan Part IV” and its broader mission to accelerate sustainable prosperity. She characterized the shareholder vote as “a vote of confidence in our visionary leader, Elon,” crediting Musk with transforming Tesla into one of the most valuable companies in history.
“In a year when many tried to sow doubt and negativity, you chose a better future,” Denholm wrote. “You chose ambition. You chose to see what is possible. You chose to back the people who have been in the room since the earliest days, fighting for the mission that first brought us all together—a better world for humanity,” she wrote in her letter.
Her comments framed Musk’s pay package approval not only as a governance milestone but as a symbolic endorsement of Tesla’s long-term trajectory across autonomy, AI, and energy innovation.
“A whole new book” of innovation
Denholm highlighted Tesla’s push toward autonomy as the company’s next major growth phase, citing the Robotaxi program and Optimus humanoid robot as examples of bringing artificial intelligence “into the physical world.” She described this period as potentially “the largest value-creation event in Tesla’s history, and quite possibly in the history of humanity.”
The letter reaffirmed the board’s commitment to direct engagement with shareholders through Tesla’s online platform and live events. Denholm emphasized that feedback from investors “informs our strategy and strengthens us” as Tesla prepares for new technology rollouts and expanded AI capabilities.

Twitter co-founder Jack Dorsey endorses Elon Musk Tesla pay package
Dorsey framed the pay package as an engineering and governance crossroads for Tesla.
Twitter co-founder and Square CEO Jack Dorsey has publicly backed Elon Musk’s leadership ahead of Tesla’s pivotal shareholder vote, which is expected to be decided later today at the company’s 2025 annual meeting.
Dorsey framed the pay package as an engineering and governance crossroads for Tesla.
Dorsey’s public nod framed as an engineering defense of Musk
In a post on X, Dorsey weighed in on Tesla’s post about being in a “critical inflection point.” As per the Twitter-co-founder, the vote on Musk’s 2025 performance award is not about compensation. Instead, it’s about ensuring the path for the company’s engineering in the coming years.
“This is not about compensation. it’s about ensuring a principled (and exciting!) engineering approach to the company’s future,” Dorsey wrote on his post, later stating that users of Cash app with TSLA shares would be able to vote for the CEO’s proposed 2025 performance award.
Elon Musk appreciated Dorsey’s endorsement, responding to the Twitter co-founder’s post with a heart emoji. Musk has been pretty thankful for the support for is fellow tech executives, also thanking Michael Dell recently, who also advocated for its proposed 2025 performance award.
Musk’s support
While Elon Musk’s 2025 performance award has received opposition from proxy advisors such as Glass Lewis and ISS, it has received quite a lot of support from longtime bulls such as ARK Invest, and, more recently, Schwab Asset Management following calls from TSLA retail shareholders.
“Schwab Asset Management’s approach to voting on proxy matters is thorough and deliberate. We utilize a structured process that focuses on protecting and promoting shareholder value. We apply our own internal guidelines and do not rely on recommendations from Glass Lewis or ISS. In accordance with this process, Schwab Asset Management intends to vote in favor of the 2025 CEO performance award proposal. We firmly believe that supporting this proposal aligns both management and shareholder interests, ensuring the best outcome for all parties involved,” Charles Schwab told Teslarati.

Tesla Robotaxi and autonomy dreams lean on shareholders: Wedbush
Tesla’s dreams of developing a Robotaxi suite that utilizes a fully autonomous platform developed by the company’s top-tier talent now lean on shareholders and perhaps the most crucial vote in its history.
That’s what Dan Ives of Wedbush said in a new note to investors on Wednesday. As the Annual Shareholders’ Meeting is now just one day away, investors are down to their final chance to vote for or against Elon Musk’s new compensation plan.
Ives wrote that, while the company has made its intentions clear, wanting to maintain Musk, pay him accordingly, and give him the voting power he has long wanted, ultimately, the responsibility falls on investors.
🚨 A new note from Wedbush’s Dan Ives on Tesla $TSLA:
“A Big Day On Deck Tomorrow for Musk and Tesla; We Expect Pay Package Passes
Tomorrow Tesla will be hosting its annual shareholder meeting with all focus on the Musk pay package on deck. We expect Musk to get overwhelming…
— TESLARATI (@Teslarati) November 5, 2025
As many retail shareholders have pushed for people to vote for Musk’s compensation package, there are a handful of large-scale funds and firms that have decided to go in another direction. Bullish Wall Street firms, Wedbush being one of them, believe it is crucial for Tesla to maintain Musk.
The vote could have major implications on whether Tesla launches an autonomous Robotaxi suite in the near future, Ives says:
“Getting Musk’s pay package approved tomorrow at the highly anticipated meeting will be a big step towards advancing Tesla’s future goals with the autonomous and Robotaxi roadmap ahead.”
While some investors are convinced the company is ready to go in a different direction simply based on Musk’s political involvement over the past year, many investors are under the impression that the development of Tesla’s autonomy suite, as well as its prowess in the EV sector, would fall if Elon were not at the helm.
Tesla’s Board of Directors has already stated that they have received confirmation that Musk’s political involvement would wind down in a timely manner. Moving forward, his focus will not veer from the mission of any of his companies; at least that’s what can be gathered from some of the Board’s communications over the past month.
Musk’s new compensation package is incentivized by performance metrics and will require him to achieve a handful of lofty tranches. He will not get paid unless he drives shareholder value, which is something many skeptics tend to leave out.
Ives continues:
“This new incentive-driven pay package for Musk would also provide an additional 423 million shares of common stock (~12% of shares), which would increase his ownership of Tesla up to ~25% voting power, which we believe was critical to keep Musk at the helm to lead Tesla through the most critical time in the company’s history. We believe this was the smart move by the Board to lay out these incentives/pay package at this key time as the biggest asset for Tesla is Musk…and with the AI Revolution, this is a crucial time for Tesla ahead with autonomous and robotics front and center.”
Wedbush maintained its Outperform rating and $600 price target on shares.
