Former Tesla 4680 battery cell production engineer James Herbermann has been named Vice President of Manufacturing at the American Battery Factory (ABF).
“James brings to American Battery Factory incredible perspective and front row experiences in evolving battery cell technology and is the perfect complement to our team as we begin our journey to develop a domestic battery manufacturing ecosystem that will make energy independence and renewable energy a reality for the United States,” ABF CEO and President Paul Charles said. “As we lay the foundation for our factory network, I am confident James’ cross-functional leadership will not only enhance the efficiency of ABF’s modular approach to manufacturing, but it will also propel our unwavering quest to develop the longest-lasting LFP prismatic battery cells on the market.”
James Herbermann, formerly with Tesla, joins American Battery Factory as its new Vice President of Manufacturing.
ABF is working to develop the United States’ first network of Lithium-Iron Phosphate, or LFP, battery cell gigafactories. The LFP cell is a major part of many automakers’ plans for future electric vehicles as more cell chemistries are being utilized to combat excessive demand. Tesla, for example, started transitioning its Standard Range trim levels to LFP batteries last year. The automaker confirmed that it would utilize the cell chemistry in lower range vehicle as they are less expensive and have longer lifespans. They do have their disadvantages, especially in terms of energy density, which means less power and range with EVs that utilize these packs. They are also more likely to be affected by adverse weather conditions, especially in colder climates.
CEO Elon Musk has said in the past that LFP packs want to be charged to 100 percent, as opposed to nickel-based packs that prefer a 90 percent state of charge.
Tesla is just one of the companies working to use LFP cells. Rivian, Ford, and Volkswagen are also utilizing the cell chemistry for some of their vehicles. Therefore, the need to produce more cells to provide automakers and customers with suitable options is definitely a work in progress.
Tesla (TSLA) Q1 2022 earnings results: Another beat with 19% operating profit and margin
ABF is working to eliminate LFP shortages with a series of production plants across the U.S., and the company is looking for Herbermann to lead and support all aspects of its manufacturing and production operations. Prior to ABF, Herbermann worked at Tesla to lead the development and scaling of its new battery electrode processes in Austin from the pilot program to a full-scale production process. He was a direct piece of Tesla’s commercialization of the 4680 cells, which has been installed in early builds of the Model Y from the new Austin factory. Additionally, Herbermann has developed “novel Sodium Titanium Phosphate; F1 racing Li-Ion cells; Aquion Hybrid Ion (AHI®); Duracell Ultra®; Comfort Plus® modular carpet tiles; and ZIP Wall® sheathing,” a press release from ABF said.
“I am inspired by ABF’s mission to develop a domestic supply chain for LFP batteries, especially in light of the pandemic’s crippling effect on availability and our country’s glaring void in battery cell manufacturing,” Herbermann said about his new role. “With its strategic approach of constructing a network of modular rapid construction factories near or onsite at pack integrators and energy solution providers, ABF is on track to solve one of the planet’s most pressing energy needs. I look forward to being a part of this impactful work.”

Elon Musk’s xAI celebrates nearly 3,000 headcount at Memphis site
The update came in a post from the xAI Memphis account on social media platform X.
xAI has announced that it now employs nearly 3,000 people in Memphis, marking more than two years of local presence in the city amid the company’s supercomputing efforts.
The update came in a post from the xAI Memphis account on social media platform X.
In a post on X, xAI’s Memphis branch stated it has been part of the community for over two years and now employs “almost 3,000 locally to help power Grok.” The post was accompanied by a photo of the xAI Memphis team posing for a rather fun selfie.
“xAI is proud to be a member of the Memphis community for over two years. We now employ almost 3,000 locally to help power @Grok. From electricians to engineers, cooks to construction — we’re grateful for everyone on our team!” the xAI Memphis’ official X account wrote.
xAI’s Memphis facilities are home to Grok’s foundational supercomputing infrastructure, including Colossus, a large-scale AI training cluster designed to support the company’s advanced models. The site, located in South Memphis, was announced in 2024 as the home of one of the world’s largest AI compute facilities.
The first phase of Colossus was built out in record time, reaching its initial 100,000 GPU operational status in just 122 days. Industry experts such as Nvidia CEO Jensen Huang noted that this was significantly faster than the typical 2-to-4-year timeline for similar projects.
xAI chose Memphis for its supercomputing operations because of the city’s central location, skilled workforce, and existing industrial infrastructure, as per the company’s statements about its commitment to the region. The initiative aims to create hundreds of permanent jobs, partner with local businesses, and contribute to economic and educational efforts across the area.
Colossus is intended to support a full training pipeline for Grok and future models, with xAI planning to scale the site to millions of GPUs.

Ford embraces Tesla-style gigacastings and Cybertruck’s 48V architecture
Ford Motor Company’s next-generation electric vehicles will adopt technologies that were first commercialized by the Tesla Cybertruck.
Ford Motor Company’s next-generation electric vehicles will adopt technologies that were first commercialized by the Tesla Cybertruck, such as the brutalist all-electric pickup’s 48-volt electrical architecture and its gigacastings.
The shift is expected to start with a roughly $30,000 small electric pickup that is expected to be released in 2027, which is part of Ford’s $5 billion investment in its new Universal EV platform, as noted in a CNBC report.
Ford confirmed that its upcoming EV platform will move away from the traditional 12-volt system long used across the auto industry. Instead, it will implement a 48-volt electrical architecture that draws power directly from the vehicle’s high-voltage battery.
Tesla was the first automaker to bring a 48-volt system to U.S. consumers with the Cybertruck in 2023. The architecture reduces wiring bulk, lowers weight, and improves electrical efficiency. It also allows power to be stepped down to 12 volts through new electronic control units when needed.
Alan Clarke, Ford’s executive director of advanced EV development and a former Tesla engineer, called 48-volt systems “the future of automotive” due to their lower costs and smaller wiring requirements. Ford stated that the wiring harness in its new pickup will be more than 4,000 feet shorter and 22 pounds lighter than that of its first-generation electric SUV.
Apart from the Cybertruck’s 48-volt architecture, Ford is also embracing Tesla-style gigacastings for its next-generation EVs. Ford stated that its upcoming electric vehicle will use just two major structural front and rear castings, compared with 146 comparable components in the current gas-powered Maverick.
Ford CEO Jim Farley has described the effort as a “bet” and a “Model T moment” for the company, arguing that system-level innovation is necessary to lower costs and compete globally. “At Ford, we took on the challenge many others have stopped doing. We’re taking the fight to our competition, including the Chinese,” Farley previously stated.

Tesla meets Giga New York’s Buffalo job target amid political pressures
Giga New York reported more than 3,460 statewide jobs at the end of 2025, meeting the benchmark tied to its dollar-a-year lease.
Tesla has surpassed its job commitments at Giga New York in Buffalo, easing pressure from lawmakers who threatened the company with fines, subsidy clawbacks, and dealership license revocations last year.
The company reported more than 3,460 statewide jobs at the end of 2025, meeting the benchmark tied to its dollar-a-year lease at the state-built facility.
As per an employment report reviewed by local media, Tesla employed 2,399 full-time workers at Gigafactory New York and 1,060 additional employees across the state at the end of 2025. Part-time roles pushed the total headcount of Tesla’s New York staff above the 3,460-job target.
The gains stemmed in part from a new Long Island service center, a Buffalo warehouse, and additional showrooms in White Plains and Staten Island. Tesla also said it has invested $350 million in supercomputing infrastructure at the site and has begun manufacturing solar panels.
Empire State Development CEO Hope Knight said the agency was “very happy” with Giga New York’s progress, as noted in a WXXI report. The current lease runs through 2029, and negotiations over updated terms have included potential adjustments to job requirements and future rent payments.
Some lawmakers remain skeptical, however. Assemblymember Pat Burke questioned whether the reported job figures have been fully verified. State Sen. Patricia Fahy has also continued to sponsor legislation that would revoke Tesla’s company-owned dealership licenses in New York. John Kaehny of Reinvent Albany has argued that the project has not delivered the manufacturing impact originally promised as well.
Knight, for her part, maintained that Empire State Development has been making the best of a difficult situation.
“(Empire State Development) has tried to make the best of a very difficult situation. There hasn’t been another use that has come forward that would replace this one, and so to the extent that we’re in this place, the fact that 2,000 families at (Giga New York) are being supported through the activity of this employer. It’s the best that we can have happen,” the CEO noted.
