Tesla’s battery genius may hold the key to a closed-loop recycling endgame
Last year, a proverbial bomb dropped on Tesla after CTO and co-founder JB Straubel announced that he was transitioning into an advisor role and stepping away from his day-to-day duties in the company. While Straubel assured investors that he was not “disappearing” from Tesla in his final earnings call, he did stay notably under the radar following his departure. But as the date for the electric car maker’s Battery Day draws closer, it appears that some pieces are slowly falling into place suggesting that JB Straubel’s company, Redwood Materials, and Tesla, may be coming together at a key junction.
To state that JB Straubel was the backbone of Tesla’s industry-leading battery tech is no understatement. Much of the company’s breakthroughs in its battery-related efforts, such as the construction of Gigafactory Nevada, would not have been possible without Straubel’s genius. In fact, so notable were his contributions to Tesla’s battery tech in the company’s early days that he was eventually considered as a co-founder of the electric car maker.
But even during his last years at Tesla, Straubel has remarked that one key aspect remains missing from the EV transition — closed-loop battery recycling. Battery electric vehicles are great in the way that they are zero-emissions, after all, but disposing of their batteries at their end-of-life presents notable challenges under closed-loop recycling is developed. “Ultimately what we want is a closed-loop, right, at the Gigafactories that reuses the same, recycled materials,” he remarked at Tesla’s 2018 Annual Shareholders Meeting.
Prior to his departure from his day-to-day duties at Tesla, reports emerged stating that Straubel had founded a stealthy battery recycling startup called Redwood Materials. Interestingly enough, Redwood centered its operations in Nevada, the same state that hosts Tesla’s biggest battery facility to date, Gigafactory 1. When reports about Redwood initially emerged in 2018, however, Straubel was quick to note that his recycling startup’s operations are “unrelated to Tesla or to the Gigafactory directly.”
A recent report from The Wall Street Journal has now revealed some notable details that may explain some aspects of Straubel’s statement back in 2018. According to the publication, Redwood has already convinced Panasonic, Tesla’s battery partner at Gigafactory Nevada, to utilize Redwood’s technology to reclaim scrap from its operations in the facility. Panasonic reportedly started with a trial run that involved Redwood reclaiming more than 400 pounds of scrap from its Giga Nevada operations. The Japanese firm appears to have been satisfied with Redwood’s results in the trial run, as Panasonic reportedly upped its contract with the startup to 2 tons not long after.
Today, the Journal stated that all of the scrap coming from Panasonic’s side of Gigafactory Nevada’s battery production activities are being shipped to Redwood Materials for recycling. In a way, Redwood’s partnership with Panasonic seems to fit Straubel’s statement back in 2018, when he noted that his startup has no direct relation to Tesla’s operations. That being said, it is evident that Redwood’s tech is a notable step forward towards JB Straubel’s vision of a closed-loop battery recycling system.
Straubel’s plans for Redwood are ambitious, as he is looking to develop a recycling process that is so efficient that batteries coming from retired electric vehicles and energy storage units could be quickly stripped down, recycled for their core materials, and used to rebuild new batteries. With such a system in place, a closed-loop is created, and hardly any materials are lost. It’s a lofty goal, but it does hint at Straubel’s understated determination that made him such a powerful background force in Tesla.
Interestingly enough, Tesla’s new Impact Report specifically includes a section about closed-loop battery recycling. According to the electric car maker, such a setup at Gigafactory Nevada “presents a compelling solution to move energy supply away from the fossil-fuel based practice of take, make and burn, to a more circular model of recycling end-of-life batteries for reuse over and over again. From an economic perspective, we expect to recognize significant savings over the long term, as the costs associated with large-scale battery material recovery and recycling will be far lower than purchasing and transporting new materials.”
It remains to be seen if JB Straubel’s Redwood Materials and Tesla are indeed working together to recycle batteries from Gigafactory 1 and perhaps even the electric car maker’s own Roadrunner program, but despite the lack of confirmation for now, one thing is certain. One of the brightest minds in Tesla, who is arguably the genius behind the company’s battery tech and initiatives, has started a thriving company that fills in the crucial gap of battery recycling. And with such a key innovation at its doorstep, it appears out of character for Tesla to simply ignore the opportunities presented by Redwood Materials and its battery recycling technologies.

Tesla Energy is the world’s top global battery storage system provider again
Tesla Energy captured 15% of the battery storage segment’s global market share in 2024.
Tesla Energy held its top position in the global battery energy storage system (BESS) integrator market for the second consecutive year, capturing 15% of global market share in 2024, as per Wood Mackenzie’s latest rankings.
Tesla Energy’s lead, however, is shrinking, as Chinese competitors like Sungrow are steadily increasing their global footprint, particularly in European markets.
Tesla Energy dominates in North America, but its lead is narrowing globally
Tesla Energy retained its leadership in the North American market with a commanding 39% share in 2024. Sungrow, though still ranked second in the region, saw its share drop from 17% to 10%. Powin took third place, even if the company itself filed for bankruptcy earlier this year, as noted in a Solar Power World report.
On the global stage, Tesla Energy’s lead over Sungrow shrank from four points in 2023 to just one in 2024, indicating intensifying competition. Chinese firm CRRC came in third worldwide with an 8% share.
Wood Mackenzie ranked vendors based on MWh shipments with recognized revenue in 2024. According to analyst Kevin Shang, “Competition among established BESS integrators remains incredibly intense. Seven of the top 10 vendors last year struggled to expand their market share, remaining either unchanged or declining.”
Chinese integrators surge in Europe, falter in U.S.
China’s influence on the BESS market continues to grow, with seven of the global top 10 BESS integrators now headquartered in the country. Chinese companies saw a 67% year-over-year increase in European market share, and four of the top 10 BESS vendors in Europe are now based in China. In contrast, Chinese companies’ market share in North America dropped more than 30%, from 23% to 16% amid Tesla Energy’s momentum and the Trump administration’s policies.
Wood Mackenzie noted that success in the global BESS space will hinge on companies’ ability to adapt to divergent regulations and geopolitical headwinds. “The global BESS integrator landscape is becoming increasingly complex, with regional trade policies and geopolitical tensions reshaping competitive dynamics,” Shang noted, pointing to Tesla’s maintained lead and the rapid ascent of Chinese rivals as signs of a shifting industry balance.
“While Tesla maintains its global leadership, the rapid rise of Chinese integrators in Europe and their dominance in emerging markets like the Middle East signals a fundamental shift in the industry. Success will increasingly depend on companies’ ability to navigate diverse regulatory environments, adapt to local market requirements, and maintain competitive cost structures across multiple regions,” the analyst added.

Tesla inks multi-billion-dollar deal with LG Energy Solution to avoid tariff pressure
Tesla has reportedly secured a sizable partnership with LGES for LFP cells, and there’s an extra positive out of it.
Tesla has reportedly inked a multi-billion-dollar deal with LG Energy Solution in an effort to avoid tariff pressure and domesticate more of its supply chain.
Reuters is reporting that Tesla and LGES, a South Korean battery supplier of the automaker, signed a $4.3 billion deal for energy storage system batteries. The cells are going to be manufactured by LGES at its U.S. factory located in Michigan, the report indicates. The batteries will be the lithium iron phosphate, or LFP, chemistry.
Tesla delivers 384,000 vehicles in Q2 2025, deploys 9.6 GWh in energy storage
It is a move Tesla is making to avoid buying cells and parts from overseas as the Trump White House continues to use tariffs to prioritize domestic manufacturing.
LGES announced earlier today that it had signed a $4.3 billion contract to supply LFP cells over three years to a company, but it did not identify the customer, nor did the company state whether the batteries would be used in automotive or energy storage applications.
The deal is advantageous for both companies. Tesla is going to alleviate its reliance on battery cells that are built out of the country, so it’s going to be able to take some financial pressure off itself.
For LGES, the company has reported that it has experienced slowed demand for its cells in terms of automotive applications. It planned to offset this demand lag with more projects involving the cells in energy storage projects. This has been helped by the need for these systems at data centers used for AI.
During the Q1 Earnings Call, Tesla CFO Vaibhav Taneja confirmed that the company’s energy division had been impacted by the need to source cells from China-based suppliers. He went on to say that the company would work on “securing additional supply chain from non-China-based suppliers.”
It seems as if Tesla has managed to secure some of this needed domestic supply chain.

Tesla Shanghai Megafactory produces 1,000th Megapack for export to Europe
The Shanghai Megafactory was able to hit this milestone less than six months after it started producing the Megapack.
Tesla Energy has announced a fresh milestone for its newest Megapack factory. As per the electric vehicle maker, the Shanghai Megafactory has successfully produced its 1,000th Megapack battery.
The facility was able to hit this milestone less than six months after it started producing the grid-scale battery system.
New Tesla Megapack Milestone
As per Tesla Asia in a post on its official accounts on social media platform X, the 1,000th Megapack unit that was produced at the Shanghai Megafactory would be exported to Europe. As noted in a CNEV Post report, Tesla’s energy products are currently deployed in over 65 countries and regions globally. This allows Tesla Energy to compete in energy markets that are both emerging and mature.
To commemorate the 1,000th Megapack produced at the Shanghai Megafactory, the Tesla China team posted with the grid-scale battery with celebratory balloons that spelled “Megapack 1000.” The milestone was celebrated by Tesla enthusiasts on social media, especially since the Shanghai Megafactory only started its operations earlier this year.
Quick Megafactory Ramp
The Shanghai Megafactory, similar to Tesla’s other key facilities in China, was constructed quickly. The facility started its construction on May 23, 2024, and it was hailed as Tesla’s first entry storage project outside the United States. Less than a year later, on February 11, 2025, the Shanghai Megafactory officially started producing Megapack batteries. And by March 21, 2025, Tesla China noted that it had shipped the first batch of Megapack batteries from the Shanghai plant to foreign markets.
While the Shanghai Megafactory is still not at the same level of output as Tesla’s Lathrop Megafactory, which produces about 10,000 Megapacks per year, its ramp seems to be quite steady and quick. It would then not be surprising if Tesla China announces the Shanghai Megafactory’s 2,000th Megapack milestone in the coming months.
