Tesla addresses Zero-Cobalt future in latest Impact Report
Tesla outlined its goal for responsible Cobalt sourcing in its latest 2019 Impact Report, released on June 8, 2020.
The automaker plans to eventually produce a zero-cobalt battery for its vehicles and energy products, in its bid to source metals in a responsible fashion that maintains not only the integrity of the company but also the human rights of those involved in the sourcing of raw materials.
“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,” notes Tesla in its Impact Report.
Tesla’s lithium-ion batteries utilize an NCA Cathode makeup, comprised of a Nickel-Cobalt-Aluminum structure. The combination of the three metals creates a battery that has longevity and stability throughout the life cycle of the vehicle. Cobalt supplies a battery with high-rate performance and enhances cycle stability when exposed to high levels of heat, according to ScienceMag.
Cobalt, while controversial, is a crucial element in lithium-ion batteries, at least for now. While Tesla continues to work toward the omittance of the element from its batteries, the challenge is finding another metal that can replace Cobalt while maintaining the integrity of the battery.
-->Under a section titled “Supply Chain Introduction: Responsible Material Sourcing,” Tesla addresses and details its “Supplier Code of Conduct” and “Human Rights and Conflict Minerals Policy.” The two documents outline the company’s expectations for its suppliers and partners and require all members of the Tesla supply chain to uphold responsible and integrity-focused techniques when acquiring Cobalt.
“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 report indicates.
Tesla’s plans to utilize zero-Cobalt batteries are certainly in the company’s future plans. However, while the element is still included in the current battery makeup, responsible sourcing is among Tesla’s main concerns.
Suppliers involved in sourcing Cobalt for the electric automaker are required and expected to follow Tesla’s Code of Business Conduct and Ethics. Although many of the company’s direct suppliers obtain some raw materials through sub-contractors, Tesla conducts due diligence practices that maintain the safety and respect of workers everywhere.
Tesla has even gone as far as removing some risks from its supply chain. The report explicitly mentions areas notorious for child labor, especially in the field of Cobalt mining. “Because Tesla recognizes the higher risks of human rights issues within cobalt supply chains, particularly for child labor in the Democratic Republic of Congo, we have made a significant effort to establish processes to remove these risks from our supply chain,” the company wrote.
-->The eventual phasing out of Cobalt from the batteries Tesla uses requires an extreme process of due diligence, now. Cobalt has been one of the primary sources of criticism for non-EV supporters. In particular, the issue of child labor has driven as much skepticism from critics as nearly any other topic. However, the regular auditing and due diligence have helped Tesla maintain responsible labor and material acquisition practices, effectively eliminating any criticism for utilizing Cobalt at the current time.
Currently, the company’s cells use nickel-rich cathode materials and contain less Cobalt than any other widely used cathode chemistries in the EV sector. Eventually, zero-Cobalt batteries will be introduced into Tesla’s EVs Still, a controversial subject like the sourcing of the metal requires a tedious and specific amount of verification through a series of annual third-party audits.
The transparency that Tesla provides throughout the Impact Report’s Cobalt Sourcing section shows a responsible process of mining the metal. Tesla states that it has mapped significant areas of the Cobalt supply chain, and ethics concerning sourcing the metal will continue to improve over time.

Tesla Semi factory looks almost complete during Thanksgiving weekend
Based on recent drone videos, the Tesla Semi factory looks practically ready to start operations.
It appears that the Tesla Semi factory near Giga Nevada is already hard at work preparing for the initial production of the Class 8 all-electric truck. This was, at least, hinted at in a recent drone flyover of the facility from a longtime watcher.
The Tesla Semi factory after Thanksgiving
Drone operator and Tesla Semi advocate @HinrichsZane recently shared some footage he captured of the upcoming facility during the Thanksgiving weekend. Based on his video, it appears that Tesla gave its employees in the area the weekend off. One thing is evident from the video, however, and that is the fact that the Tesla Semi factory looks practically ready to start operations.
The Tesla Semi watcher did point out that the electric vehicle maker is still busy bringing in production equipment into the facility itself. Once these are installed, it would not be surprising if initial production of the Tesla Semi begins.
A new Tesla Semi
The upcoming completion of the Tesla Semi factory near Gigafactory Nevada seems all but inevitable in the coming months. What would be especially interesting, however, would be the vehicles that would be produced on the site. During Elon Musk’s presentation at the 2025 Annual Shareholder Meeting, a glimpse of the production Tesla Semi was shown, and it looks quite a bit different than the Class 8 all-electric truck’s classic appearance.
As could be seen in the graphic from the CEO’s presentation, the updated Tesla Semi will feature slim lightbar headlights similar to the new Tesla Model Y, Cybertruck, and the Cybercab. Tesla also teased a number of aerodynamic improvements that increased the truck’s efficiency to 1.7 kWh per mile. Extended camera units, seemingly for FSD, could also be seen in the graphic.

Tesla scores major hire as Apple scientist moves to Optimus team
Chen, who advanced from individual contributor to technical lead during his time at Apple, noted that he was blown away by Tesla’s efforts and synergy.
Former Apple research scientist Yilun Chen has left the tech giant to join Tesla’s Optimus AI team. Chen, who advanced from individual contributor to technical lead during his time at Apple, noted that he was blown away by Tesla’s efforts and synergy.
Apple veteran closes a major chapter
In a farewell note, Yilun Chen reflected on his tenure at Apple as a period defined by rapid growth and exposure to notable internal projects, some of which remain unreleased. His roles spanned engineering, research, early product incubation, and hands-on prototyping, allowing him to build expertise across both mature and emerging teams.
Chen credited mentors, colleagues, and cross-functional collaborators for shaping his trajectory, calling the experience unforgettable and emphasizing how each team taught him different lessons about scaling technology, guiding product vision, and navigating fast-moving research environments. “Each role has offered me invaluable unique lessons… My deepest gratitude goes to my colleagues, mentors and friends,” he wrote.
Tesla’s Optimus lab secured the hire
Chen said the move to Tesla was driven by the momentum surrounding Optimus, a humanoid robot powered by LLM-driven reasoning and Physical AI. After visiting Tesla’s Optimus lab, he admitted that he was “totally blown away by the scale and sophistication of the Optimus lab and deep dedication of people when I got to visit the office.”
His first week at Tesla, he noted, involved spontaneous deep-tech discussions, a flat team structure, rapid prototyping cycles, and what he called a “crazy ideas with super-fast iterations” culture. Chen emphasized that the team’s ambition, as well as its belief that humanoid robots are now within reach, creates an energy level that feels aimed at changing the world.
-->“You can feel the energy to change the world here,” he wrote in a post on social media.

Elon Musk gives nod to SpaceX’s massive, previously impossible feat
It was the booster’s 30th flight, a scenario that seemed impossible before SpaceX became a dominant force in spaceflight.
Elon Musk gave a nod to one of SpaceX’s most underrated feats today. Following the successful launch of the Transporter-15 mission, SpaceX seamlessly landed another Falcon 9 booster on a droneship in the middle of the ocean.
It was the booster’s 30th flight, a scenario that seemed impossible before SpaceX became a dominant force in spaceflight.
Elon Musk celebrates a veteran Falcon 9 booster’s feat
SpaceX completed another major milestone for its Smallsat Rideshare program on Friday, successfully launching and deploying 140 spacecraft aboard a Falcon 9 from Vandenberg Space Force Base. The mission, known as Transporter-15, lifted off two days later than planned after a scrub attributed to a ground systems issue, according to SpaceFlight Now. SpaceX confirmed that all payloads designed to separate from the rocket were deployed as planned.
The Falcon 9 used for this flight was booster B1071, one of SpaceX’s most heavily flown rockets. With its 30th mission completed, it becomes the second booster in SpaceX’s fleet to reach that milestone. B1071’s manifest includes five National Reconnaissance Office missions, NASA’s SWOT satellite, and several previous rideshare deployments, among others. Elon Musk celebrated the milestone on X, writing “30 flights of the same rocket!” in his post.
Skeptics once dismissed reusability as unfeasible
While rocket landings are routine for SpaceX today, that was not always the case. Industry veterans previously questioned whether reusable rockets could ever achieve meaningful cost savings or operational reliability, often citing the Space Shuttle’s partial reusability as evidence of failure.
-->In 2016, Orbital ATK’s Ben Goldberg argued during a panel that even if rockets could be reusable, they do not make a lot of sense. He took issue with Elon Musk’s claims at the time, Ars Technica reported, particularly when the SpaceX founder stated that fuel costs account for just a fraction of launch costs.
Goldberg noted that at most, studies showed only a 30% cost reduction for low-Earth orbit missions by using a reusable rocket. “You’re not going to get 100-fold. These numbers aren’t going to change by an order of magnitude. They’re just not. That’s the state of where we are today,” he said.
Former NASA official Dan Dumbacher, who oversaw the Space Launch System, expressed similar doubts in 2014, implying that if NASA couldn’t make full reusability viable, private firms like SpaceX faced steep odds.
