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.

Houston autonomous trucking co. completes first test run without human intervention

on the road

Houston-based Bot Auto, an autonomous trucking company, has completed its first test run without human assistance. Bot Auto conducted the test in Houston.

“The truck operated seamlessly within its defined operational domain with no one in the cab or remote assistance, navigating real-world traffic conditions,” the company said in a news release. “The run was executed at sunset, successfully navigating day and night operations.”

Bot Auto, a transportation-as-a-service startup, added that this milestone “serves as a validation benchmark, demonstrating the maturity and safety of Bot Auto’s autonomy stack and test protocols.”

The successful test comes two years after Xiaodi Hou, a globally recognized expert in autonomous vehicles, founded Bot Auto.

“This validation run is a meaningful step, but it’s a waypoint, not the destination,” Hou, CEO of Bot Auto, added in the release. “Success is simple: Autonomy must beat human cost-per-mile, consistently and safely. And at Bot Auto, humanless means no human — not in the driver’s seat, not in the back seat, and not behind a remote joystick.”

For several months, Bot Auto has been conducting autonomous trucking tests on a Houston-to-San Antonio route. In the coming months, Bot Auto will operate its first commercial cargo run without human assistance between its Houston and San Antonio hubs.

“Our mission is to revolutionize the transportation industry with our autonomous trucks, making a lasting positive impact on humanity,” the company says.

Last October, Bot Auto announced it had raised $20 million in pre-series A funding from Brightway Future Capital, Cherubic Ventures, EnvisionX Capital, First Star Ventures, Linear Capital, M31 Capital, Taihill Venture, Uphonest Capital, and Welight Capital.

This summer, Hou told the Front Lines podcast that Bot Auto had raised more than $45 million altogether.

Hobby debuts solar canopy as airport system reaches new sustainability milestone

solar solutions

Houston's William P. Hobby Airport is generating its own clean energy.

Houston Aiports announced that Hobby's red garage is now home to a "solar canopy" that is producing energy at 100 percent capacity to power daily operations. The photovoltaic (PV) solar system generated more than 1.1 gigawatt-hours of electricity in testing, and is expected to produce up to 1 megawatt-hour now that it's operating at full power.

“This project is proof that sustainability can be practical, visible and directly tied to the passenger experience,” Jim Szczesniak, director of aviation for Houston Airports, said in a news release. “Passengers now park under a structure that shields their cars from the Texas sun while generating clean energy that keeps airport operations running efficiently, lowering overall peak demand electrical costs during the day and our carbon footprint. It’s a win for travelers, the city and the planet.”

The project was completed by Texas A&M Engineering Experiment Station (TEES) and CenterPoint Energy. It's part of Houston Airport's efforts to reduce carbon emissions by 40 percent over its 2019 baseline.

In a separate announcement, the airport system also shared that it recently reached Level 3 in the Airports Council International (ACI) Airport Carbon Accreditation program after reducing emissions by 19 percent in three years. This includes reductions at George Bush Intercontinental Airport (IAH), Hobby and Ellington Airport/Houston Spaceport.

The reductions have come from initiatives such as adding electric vehicles to airport fleets, upgrading airfield lighting with LED bulbs, adding smarter power systems to terminals, and improving IAH's central utility plant with more efficient equipment. Additionally, the expansion to Hobby's West Concourse and renovations at IAH Terminal B incorporate cleaner equipment and technology.

According to Houston Airports, from 2019 to 2023:

  • IAH reduced emissions by 17 percent
  • Hobby reduced emissions by 32 percent
  • Ellington Airport reduced emissions by 4 percent

"I see firsthand how vital it is to link infrastructure with sustainability,” Houston City Council Member Twila Carter, chair of the council’s Resilience Committee, said in the release. “Reducing carbon emissions at our airports isn’t just about cleaner travel — it’s about smarter planning, safer communities and building a Houston that can thrive for generations to come.”

Houston health orgs lost $58M in canceled, stalled NIH grants, new report shows

research cuts

Seven institutions in the Houston area have lost nearly $60 million in grants from the National Institutes of Health (NIH) that were aimed at funding health research.

The Science & Community Impacts Mapping Project identified 37 cancelled or frozen NIH grants worth $58.7 million that were awarded to seven Houston-area institutions. The University of Texas Medical Branch at Galveston suffered the biggest loss — five grants totaling nearly $44.8 million.

The Harvard University T.H. Chan School of Public Health reported in May that over the previous several months across the U.S., the federal government had terminated roughly 2,100 NIH research grants worth around $9.5 billion.

In August, the U.S. Supreme Court derailed researchers’ efforts to reinstate almost $2 billion in research grants issued by NIH, according to Nature.com.

“Make no mistake: This was a decision critical to the future of the nation, and the Supreme Court made the wrong choice. History will look upon these mass National Institutes of Health (NIH) research grant terminations with shame,” the American Association of Medical Colleges said in a statement. “The Court has turned a blind eye to this grievous attack on science and medicine, and we call upon Congress to take action to restore the rule of law at NIH.”

Texas health researchers rely heavily on NIH grants and contracts. During the federal government’s 2024 budget year, NIH awarded $1.9 billion in grants and contracts that directly supported 30,553 jobs and more than $6.1 billion in economic activity in Texas, according to the United for Medical Research coalition.

Here’s a rundown of the cancelled and frozen NIH grants in the Houston area.

  • University of Texas Medical Branch at Galveston: Five cancelled or frozen grants, totalling approximately $44.8 million in funding lost.
  • Baylor College of Medicine: 17 grants cancelled or frozen, totalling approximately $8 million in funding lost
  • University of Houston. Five cancelled or frozen grants, totalling approximately $3.7 million in funding lost
  • University of Texas Health Science Center Houston: Five grants cancelled or frozen, totaling approximately $1.1 million in funding lost.
  • University of Texas MD Anderson Cancer Center: Two grants cancelled or frozen, totalling $831,581 in funding
  • Rice University. Two grants cancelled or frozen, totaling $254,645 in funding lost
  • Prairie View A&M University: One grant cancelled or frozen, totalling $31,771 in funding lost
