The “missing link” in critical minerals may have been in our junk drawers all along, according to new research from the University of Houston.

Jian Shi, an associate professor in the UH Cullen College of Engineering, and his team have unveiled a new supply chain model that aims to make e-waste economically viable and could help make large-scale recycling possible.

Shi, along with professor Kailai Wang and graduate researcher Chuyue Wang, published the work in a recent issue of Nature. Their study outlines how gold, lithium and cobalt from discarded electronics can be kept circulating in the U.S. through the process of “urban mining.” It was supported by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE) through the Vehicle Technologies Office.

The team’s research found that e-waste is the fastest-growing solid waste stream in the world. When waste from smartphones or tablets is left unmanaged, the devices can leak hazardous waste and pose significant fire risks due to aging batteries. Additionally, when they are shipped off to foreign landfills, the U.S. loses the potential to recycle or reuse the critical minerals left inside.

“A lot of people have iPads or old iPhones sitting in their drawers right now, and that’s a waste of a critical resource,” Shi said in a news release. “Urban mining allows us to extract the same high-value materials found in traditional mines without the environmental destruction. More importantly, it helps secure our domestic supply chain for the technologies of tomorrow.”

According to UH, recycling e-waste has not succeeded in the U.S. due to a fragmented recycling system, in which manufacturers, collectors and recyclers operate separately, driving up costs.

The UH team's research looks to change that.

In the study, the researchers modeled streamlined recycling efforts by mapping the interactions between manufacturers and independent recycling markets. Their dual-channel closed-loop supply chain (CLSC) model identified how these players can transition from competitors to partners, which can distribute profits more equitably and make recycling efforts more financially attractive.

According to UH, the research has particular significance due to the growing demand for electronic vehicles and their batteries.

“We can improve the performance of the entire recycling ecosystem and make the profit distribution more balanced,” Wang said in the release. “This ensures that the materials we need for EVs and advanced electronics stay right here in the U.S.”

“By making recycling work at scale, we aren’t just cleaning up waste,” Shi added. “We’re building a foundation that benefits both our national security and our economy.”

Houston team’s discovery brings solid-state batteries closer to EV use

a better battery

A team of researchers from the University of Houston, Rice University and Brown University has uncovered new findings that could extend battery life and potentially change the electric vehicle landscape.

The team, led by Yan Yao, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Electrical and Computer Engineering at UH, recently published its findings in the journal Nature Communications.

The work deployed a powerful, high-resolution imaging technique known as operando scanning electron microscopy to better understand why solid-state batteries break down and what could be done to slow the process.

“This research solves a long-standing mystery about why solid-state batteries sometimes fail,” Yao, corresponding author of the study, said in a news release. “This discovery allows solid-state batteries to operate under lower pressure, which can reduce the need for bulky external casing and improve overall safety.”

A solid-state battery replaces liquid electrolytes found in conventional lithium-ion cells with a solid separator, according to Car and Driver. They also boast faster recharging capabilities, better safety and higher energy density.

However, when it comes to EVs, solid-state batteries are not ideal since they require high external stack pressure to stay intact while operating.

Yao’s team learned that tiny empty spaces, or voids, form within the solid-state batteries and merge into a large gap, which causes them to fail. The team found that adding small amounts of alloying elements, like magnesium, can help close the voids and help the battery continue to function. The team captured it in real-time with high-resolution videos that showed what happens inside a battery while it’s working under a scanning electron microscope.

“By carefully adjusting the battery’s chemistry, we can significantly lower the pressure needed to keep it stable,” Lihong Zhao, the first author of this work, a former postdoctoral researcher in Yao’s lab and now an assistant professor of electrical and computer engineering at UH, said in the release. “This breakthrough brings solid-state batteries much closer to being ready for real-world EV applications.”

The team says it plans to build on the alloy concept and explore other metals that could improve battery performance in the future.

“It’s about making future energy storage more reliable for everyone,” Zhao added.

The research was supported by the U.S. Department of Energy’s Battery 500 Consortium under the Vehicle Technologies Program. Other contributors were Min Feng from Brown; Chaoshan Wu, Liqun Guo, Zhaoyang Chen, Samprash Risal and Zheng Fan from UH; and Qing Ai and Jun Lou from Rice.

US awards $3B for EV battery production in Texas, other states

charging up

The Biden administration is awarding over $3 billion to U.S. companies to boost domestic production of advanced batteries and other materials used for electric vehicles, part of a continuing push to reduce China’s global dominance in battery production for EVs and other electronics.

The grants will fund a total of 25 projects in 14 states, including Texas, as well as Ohio, South Carolina, Michigan, North Carolina, and Louisiana.

The grants announced Friday mark the second round of EV battery funding under the bipartisan infrastructure law approved in 2021. An earlier round allocated $1.8 billion for 14 projects that are ongoing. The totals are down from amounts officials announced in October 2022 and reflect a number of projects that were withdrawn or rejected by U.S. officials during sometimes lengthy negotiations.

The money is part of a larger effort by President Joe Biden and Vice President Kamala Harris to boost production and sales of electric vehicles as a key element of their strategy to slow climate change and build up U.S. manufacturing. Companies receiving awards process lithium, graphite or other battery materials, or manufacture components used in EV batteries.

“Today’s awards move us closer to achieving the administration’s goal of building an end-to-end supply chain for batteries and critical minerals here in America, from mining to processing to manufacturing and recycling, which is vital to reduce China’s dominance of this critical sector,'' White House economic adviser Lael Brainard said.

The Biden-Harris administration is "committed to making batteries in the United States that are going to be vital for powering our grid, our homes and businesses and America’s iconic auto industry,'' Brainard told reporters Thursday during a White House call.

The awards announced Friday bring to nearly $35 billion total U.S. investments to bolster domestic critical minerals and battery supply chains, Brainard said, citing projects from major lithium mines in Nevada and North Carolina to battery factories in Michigan and Ohio to production of rare earth elements and magnets in California and Texas.

“We’re using every tool at our disposal, from grants and loans to allocated tax credits,'' she said, adding that the administration's approach has leveraged more $100 billion in private sector investment since Biden took office.

In recent years, China has cornered the market for processing and refining key minerals such as lithium, rare earth elements and gallium, and also has dominated battery production, leaving the U.S. and its allies and partners "vulnerable,'' Brainard said.

The U.S. has responded by taking what she called “tough, targeted measures to enforce against unfair actions by China.” Just last week, officials finalized higher tariffs on Chinese imports of critical minerals such as graphite used in EV and grid-storage batteries. The administration also has acted under the 2022 climate law to incentivize domestic sourcing for EVs sold in the U.S. and placed restrictions on products from China and other adversaries labeled by the U.S. as foreign entities of concern.

"We're committed to making batteries in the United States of America,'' Energy Secretary Jennifer Granholm said.

If finalized, awards announced Friday will support 25 projects with 8,000 construction jobs and over 4,000 permanent jobs, officials said. Companies will be required to match grants on a 50-50 basis, with a minimum $50 million investment, the Energy Department said.

While federal funding may not be make-or-break for some projects, the infusion of cash from the infrastructure and climate laws has dramatically transformed the U.S. battery manufacturing sector in the past few years, said Matthew McDowell, associate professor of engineering at Georgia Institute of Technology.

McDowell said he is excited about the next generation of batteries for clean energy storage, including solid state batteries, which could potentially hold more energy than lithium ion.

ExxonMobil enters into off-take agreement with EV battery manufacturer

it's a deal

ExxonMobil has signed a non-binding memorandum of understanding with South Korean electric vehicle battery developer SK On.

The deal aims to secure a multiyear off-take agreement of up to 100,000 metric tons of MobilTM Lithium from the company’s first planned project in Arkansas. SK On will use the lithium in its EV battery manufacturing operations in the United States, which will contribute to ExxonMobil’s 2023 goal of supplying lithium for nearly 1 million EV batteries annually by 2030, and also assist in the build out of a U.S. EV supply chain.

The Arkansas project proposes an extraction of lithium from underground saltwater deposits and converting it into battery-grade material onsite. The approach will produce lithium more efficiently and with fewer environmental impacts than traditional hard rock mining, according to ExxonMobil. Consumer electronics, energy storage systems, and other clean energy technologies have all shown increased use in lithium needs.

The planned production of MobilTM Lithium will use ExxonMobil's core capabilities in drilling, subsurface exploration, and chemical processing, which should offer U.S. EV battery manufacturers a lower-carbon lithium supply option.

“The world needs more lithium to support its emissions goals, and we're doing our part to drive solutions forward in the United States,” Dan Ammann, president of ExxonMobil Low Carbon Solutions, says in a news release. “This collaboration with SK On demonstrates the leading role we play in the growing market for domestically sourced lithium, a market that’s advancing energy security and climate objectives, as well as supporting American manufacturing."

The annual production capacity of SK On in the U.S. alone is expected to reach more than 180 GWh in 2025. That production is enough to power around 1.7 million EVs per year.

“Through this partnership with ExxonMobil, we will continue strengthening battery supply chains in the U.S.,” Park Jong-jin, executive vice president of Strategic Procurement at SK On, adds.

Tesla's EV Robotaxis officially launch in Texas' largest metros

On The Road

Tesla’s Robotaxi service has taken to the streets of Houston. In a brief statement Saturday, April 18 on its X social media account, Tesla Robotaxi says the autonomous rideshare service just launched in Texas’ two biggest metro areas — Houston and Dallas.

“Try Tesla Robotaxi in Dallas & Houston!” Tesla CEO Elon Musk says in a reposting on X of the Robotaxi announcement.

One of Robotaxi’s competitors, Alphabet-owned Waymo, beat the Tesla service to the Dallas, Houston, and Austin markets. Another competitor, Amazon-owned Zoox, has Dallas flagged for its autonomous rideshare service.

Robotaxi previously kicked off in Austin, where Tesla is based and manufactures electric vehicles, and the San Francisco Bay Area. Nearly 50 Robotaxis operate in Austin, where the service’s inaugural rides happened last year, and more than 500 in the San Francisco area.

Of the three rides logged in a 31-square-mile area in Dallas as of Monday morning, the average fare was $7.96 and the average trip was 3.5 miles, according to an online tracker of autonomous rideshare services. The tracker showed only one Robotaxi was on the roads in Dallas.

As of Monday morning, a 25-square-mile area in Houston had two Robotaxis on the road, according to the online tracker. The average fare for five recorded rides was $11.34 and the average trip was six miles.

“We want Robotaxi pricing to be simple and easy for you to understand,” according to the Robotaxi website. “Initially, as part of our introductory program, we will charge a simple, affordable rate plus applicable taxes and fees for all rides within the available service area.”

The tracker shows the Robotaxi in Dallas did not have a human aboard to monitor each trip, and only one of Houston’s two Robotaxis did not have a human monitor in the driver’s seat.

For now, all passengers ride in Tesla Model Y cars. Robotaxi operates from 6 am-2 am daily.

To use the service, you first must download the Robotaxi app, which works only on iPhones.

Robotaxi lets you stream music and adjust climate settings and seat positioning from the Robotaxi app or the vehicle’s touchscreen. Climate and media settings are stored in your Robotaxi profile and automatically transfer from one vehicle to another. If you own a Tesla, certain profile settings and media preferences are available in your own car as well as in a Robotaxi.

In January at the World Economic Forum in Davos, Switzerland, Musk said a “widespread” network of driverless rideshare vehicles would be operating in the U.S. by the end of this year, CNBC reported.
