Former Tesla co-founder JB Straubel’s battery recycling startup Redwood Materials announced recently that it had come to terms with Envision AESC for cell recycling efforts. After CNBC initially reported the partnership yesterday, Teslarati spoke to the battery recycling startup, indicating there are plenty of details that make the pairing ideal for the entire EV sector.
While Redwood’s most recent announcement sheds light on a partnership with AESC, it is not the only contributor to the batter recycling efforts that Straubel’s company is working on. With the conglomerate’s announcement, Redwood now works with the two largest battery manufacturing companies in North America. Along with AESC, Redwood is also working with Panasonic, Tesla’s supplier at its factory in Sparks, Nevada, known as the Tesla Gigafactory. While Envision AESC works out of Tennessee, Redwood has established two battery cell producers in separate regions of the United States, working on expanding its footprint of possible EV manufacturers who need assistance in responsibly disposing of their batteries.
Resuing battery materials will eliminate some criticism regarding mining, which can be hazardous to the environment. Ultimately, Redwood aims to give EV manufacturers the ability to reuse their materials, and it has gotten to the point that the difference between new and recycled materials is relatively “indistinguishable,” Straubel said.
However, Bill Williams, Envision AESC’s Director of Business Development, also chimed in on the partnership with Redwood. The two companies’ goals of sustainability and cost-effectiveness will help the development of the electric vehicle sector, along with the ongoing production of energy storage products that are becoming more popular.
Williams said:
“Envision AESC’s partnership with Redwood Materials will allow all production scrap from our US factory to be recycled, and, eventually, for Redwood to supply material for AESC. This circular supply chain supports Envision AESC’s deep commitment to sustainability and already creates substantial cost savings for Envision AESC that will be passed down to future electric vehicles and energy products.”

Batteries from AESC’s facility in Smyrna, Tennessee, are being used to power electric buses, energy storage units, and the Nissan LEAF, among many other products, a Redwood spokesperson told Teslarati. Additionally, the material being received by Redwood from both the Tesla Gigafactory makes up for more than 1 GWh of material from Panasonic alone. This is ultimately fueled by the expansion of the Gigafactory, and the material received by Redwood will return to Panasonic and be put into new batteries, according to Redwood’s spokesperson.
Redwood will recycle all production scrap from any of its partners, including cathode and anode materials and cells or battery modules that don’t pass validation and are past the point of repair. The goal of its partnership with AESC is to produce material that could eventually be returned to the supplier as a part of a fully circular supply chain, eliminating the need for massive mining pushes or extensive contracts with battery material suppliers, the spokesperson added.
Redwood’s development of recycled goods will eventually turn the EV sector into an even more sustainable industry that could lead to the complete phase-out of combustion engines altogether. If batteries are sourced properly as the EV sector continues to grow, many of the cars on the road could contain recycled materials thanks to Redwood’s initiative, turning the already Earth-friendly EV sector into one of the most sustainable industries globally.

Tesla hiring Body Fit Technicians for Cybercab’s end of line
As per Tesla’s Careers website, Body Fit Technicians for the Cybercab focus on precision body fitment work, including alignment, gap and flush adjustments.
Tesla has posted job openings for Body Fit Technicians for the Cybercab’s end-of-line assembly, an apparent indication that preparations for the vehicle’s initial production are accelerating at Giga Texas.
Body Fit Technicians for Cybercab line
As per Tesla’s Careers website, Body Fit Technicians for the Cybercab focus on precision body fitment work, including alignment, gap and flush adjustments, and certification of body assemblies to specification standards.
Employees selected for the role will collaborate with engineering and quality teams to diagnose and correct fitment and performance issues and handle detailed inspections, among other tasks.
The listing noted that candidates should be experienced with automotive body fit techniques and comfortable with physically demanding tasks such as lifting, bending, walking, and using both hand and power tools. The position is based in Austin, Texas, where Tesla’s main Cybercab production infrastructure is being built.
Cybercab poised for April production
Tesla CEO Elon Musk recently reiterated that the Cybercab is still expected to start initial production this coming April. So far, numerous Cybercab test units have been spotted across the United States, and recent posts from the official Tesla Robotaxi account have revealed that winter tests in Alaska for the autonomous two-seater are underway.
While April has been confirmed as the date for the Cybercab’s initial production, Elon Musk has also set expectations about the vehicle’s volumes in its initial months. As per the CEO, the Cybercab’s production will follow a typical S-curve, which means that early production rates for the vehicle will be very limited.
“Initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast,” Musk wrote in a post on X.

Swedish unions consider police report over Tesla Megapack Supercharger
The Tesla Megapack Supercharger opened shortly before Christmas in Arlandastad, outside Stockholm.
Swedish labor unions are considering whether to file a police report related to a newly opened Tesla Megapack Supercharger near Stockholm, citing questions about how electricity is supplied to the site. The matter has also been referred to Sweden’s energy regulator.
Tesla Megapack Supercharger
The Tesla Megapack Supercharger opened shortly before Christmas in Arlandastad, outside Stockholm. Unlike traditional charging stations, the site is powered by an on-site Megapack battery rather than a direct grid connection. Typical grid connections for Tesla charging sites in Sweden have seen challenges for nearly two years due to union blockades.
Swedish labor union IF Metall has submitted a report to the Energy Market Inspectorate, asking the authority to assess whether electricity supplied to the battery system meets regulatory requirements, as noted in a report from Dagens Arbete (DA). The Tesla Megapack on the site is charged using electricity supplied by a local company, though the specific provider has not been publicly identified.
Peter Lydell, an ombudsman at IF Metall, issued a comment about the Tesla Megapack Supercharger. “The legislation states that only companies that engage in electricity trading may supply electricity to other parties. You may not supply electricity without a permit, then you are engaging in illegal electricity trading. That is why we have reported this… This is about a company that helps Tesla circumvent the conflict measures that exist. It is clear that it is troublesome and it can also have consequences,” Lydell said.
Police report under consideration
The Swedish Electricians’ Association has also examined the Tesla Megapack Supercharger and documented its power setup. As per materials submitted to the Energy Market Inspectorate, electrical cables were reportedly routed from a property located approximately 500 meters from the charging site.
Tomas Jansson, ombudsman and deputy head of negotiations at the Swedish Electricians’ Association, stated that the union was assessing whether to file a police report related to the Tesla Megapack Supercharger. He also confirmed that the electricians’ union was coordinating with IF Metall about the matter. “We have a close collaboration with IF Metall, and we are currently investigating this. We support IF Metall in their fight for fair conditions at Tesla,” Jansson said.

Tesla HW4.5 spotted in new Model Y, triggers speculation
Owners taking delivery of recent Model Y builds have identified components labeled “AP45.”
Tesla’s Hardware 4.5 computer appears to have surfaced in newly delivered Model Y vehicles, prompting fresh speculation about an interim upgrade ahead of the company’s upcoming AI5 chip.
Owners taking delivery of recent Model Y builds have identified components labeled “AP45,” suggesting Tesla may have quietly started rolling out revised autonomy hardware.
Hardware 4.5 appears in new Model Y units
The potential Hardware 4.5 sighting was first reported by Model Y owner @Eric5un, who shared details of a Fremont-built 2026 Model Y AWD Premium delivered this January. As per the Model Y owner, the vehicle includes a new front camera housing and a 16-inch center display, along with an Autopilot computer labeled “AP45” and part number 2261336-02-A.
The Tesla owner later explained that he confirmed the part number by briefly pulling down the upper carpet liner below the Model Y’s glovebox. Other owners soon reported similar findings. One Model Y Performance owner noted that their December build also appeared to include Hardware 4.5, while another owner of an Austin-built Model Y Performance reported spotting the same “AP45” hardware.
These sightings suggest that Tesla may already be installing revised FSD computers in its new Model Y batches, despite the company not yet making any formal announcements about Hardware 4.5.
What Hardware 4.5 could represent
Clues about Hardware 4.5 have surfaced previously in Tesla’s Electronic Parts Catalog. As reported by NotATeslaApp, the catalog has listed a component described as “CAR COMPUTER – LEFT HAND DRIVE – PROVISIONED – HARDWARE 4.5.” The component, which features the part number 2261336-S2-A, is priced at $2,300.00.
Longtime Tesla hacker @greentheonly has noted that Tesla software has contained references to a possible three-SoC architecture for some time. Previous generations of Tesla’s FSD computer, including Hardware 3 and Hardware 4, use a dual-SoC design for redundancy. A three-SoC layout could allow for higher inference throughput and improved fault tolerance.
Such an architecture could also serve as a bridge to AI5, Tesla’s next-generation autonomy chip expected to enter production later in 2026. As Tesla’s neural networks grow larger and more computationally demanding, Hardware 4.5 may provide additional headroom for vehicles built before AI5 becomes widely available.
