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 mental health nonprofit expands platform statewide to connect more Texans with care

access granted

As mental health conversations evolve, the necessary pivot becomes how organizations across Texas navigate improved ways to help people access the care they need before their challenges become crises.

That’s why Mental Health America of Greater Houston recently announced that it is expanding its Care Connect platform statewide.

The expansion will address perhaps the most persistent barrier to behavioral healthcare—helping people find and navigate services that already exist.

Care Connect’s extended reach comes at a time when more than 3.5 million adults in the state live with some kind of mental health condition and scores of those in need continue to struggle with accessing care despite the growing awareness of mental health needs.

According to President and CEO Renae Vania Tomczak, Care Connect’s main goal was to remove as many obstacles as possible that Texans face when seeking mental health support.

“Care Connect was about a two-year planning process,” Tomczak says. “It really began with asking what challenges people in the Greater Houston Area were facing regarding mental health. It’s not just accessing care, but the difficulty in navigating the mental healthcare system.”

While provider shortages remain a challenge in some communities, Mental Health America of Greater Houston found that many individuals and families struggle simply to determine where to turn, how to identify the right provider and whether services are affordable.

“We wanted to make it easier for people who have questions, who may never have had a mental health challenge before, or they’re a caregiver for somebody who has a mental health issue,” Tomczak says. “We wanted to be the place that people can come to get their questions answered and be connected to care.”

Care Connect combines a vetted network of more than 1,000 providers and services across Texas with personalized navigation support.

Searches generate care results based on insurance coverage, language preferences, ZIP code and clinical specialties.

Additionally, one-on-one guidance and follow-up support are provided by bilingual resource specialists.

The platform also seeks to address affordability, one of the most significant barriers to mental healthcare access. Through participating providers, eligible individuals can receive six to eight counseling sessions at no cost.

“We have several providers who are willing to provide six to eight counseling sessions at no cost for people who do not have the means to pay for services themselves,” Tomczak says.

When provider matches are unavailable, the organization can connect individuals with master’s-level mental health professionals working under the supervision of licensed clinicians.

The statewide rollout builds on the platform’s early success in the Houston region, where it has helped thousands of individuals connect with mental health resources since launching last fall.

According to Tomczak, the decision to expand was driven in part by growing demand from outside the organization’s traditional service area.

“Last month we decided to take this program statewide,” she says. “It’s not just Houston that can use help in connecting to appropriate mental health services, but the whole state.”

The Care Connect program’s promotion through healthcare providers, community organizations and public-sector partners across Texas is now one of Mental Health America of Greater Houston’s top priorities.

Their goal is to create a stronger referral ecosystem that ultimately helps those who need access to mental health care more quickly.

To facilitate that, the organization has also added free mental health screenings to its website so that users will better identify any symptoms related to anxiety, depression and other conditions.

“Once they do that, then where do they go?” Tomczak says. “They’re not sure who to call and who can help them. At that point, we hope they’ll call us and talk to somebody live who can answer their questions and help them get started on the right path to improving their mental health.”

With eyes on the future, Tomczak believes public understanding of mental health has improved in recent years, particularly following the COVID-19 pandemic, which brought new attention to the effects of stress, isolation and uncertainty.

“The more we talk about it and have the opportunity to share that mental health conditions are traceable, the better,” she says.

According to Tomczak, long-term, Care Connect aims to reduce roadblocks that exist between recognizing the need for help and receiving it.

Ultimately, Care Connect hopes to create a robustly connected behavioral health system that gives Texans the ability to access mental health services swiftly and with confidence.

“No one should have to navigate mental health challenges alone,” Tomczak adds. “Care Connect is here to help connect people with resources, services and answers to ensure they get the care they need to take the next step toward better mental health.”

ExxonMobil sets date to make Texas its legal HQ

save the date

Energy giant Exxon Mobil Corp. has set a date to move its legal headquarters to Texas.

The Spring-based company announced this week that the redomiciliation from New Jersey to Texas is expected to be effective July 1. Exxon's board of directors unanimously recommended redomiciling in the Lone Star State in March, and shareholders approved the move to Texas at the company’s annual meeting in May.

As part of the move, ExxonMobil Holdings Corp. will replace Exxon Mobil Corp. of New Jersey and become the publicly traded parent company. Exxon reports that its shares will continue to trade on the New York Stock Exchange under the ticker symbol “XOM,” and that shareholders do not need to take action.

At the time of the recommendation, Exxon said the move would not affect business operations, management, strategy, assets or employee locations.

Exxon Chairman and CEO Darren Woods added that the redomiciliation was in part due to Texas' business-friendly environment and policies.

"Over the past several years, Texas has made a noticeable effort to embrace the business community. In doing so, it has created a policy and regulatory environment that can allow the company to maximize shareholder value,” Woods said in a news release. "Aligning our legal home with our operating home, in a state that understands our business and has a stake in the company’s success, is important.”

The Associated Press reports that about 30 percent of Exxon's employees work in Texas. Exxon's legal headquarters has been based in New Jersey since 1882, when it was Standard Oil Company.

Exxon moved its operational headquarters from Irving, Texas, to the Houston area in 2023.

Exxon was the highest-ranking Houston-area company on this year's Fortune 500 list, coming in at No. 9. Houston tied with Chicago for the second-most Fortune 500 headquarters on this year's list, with Texas leading the nation for the most Fortune 500 headquarters (57).

“Texas is the undisputed headquarters of headquarters,” Gov. Greg Abbott said in a news release. “The world’s leading businesses invest with confidence in Texas because of our welcoming business climate, predictable regulatory environment, and skilled and growing workforce. People and businesses are choosing Texas because Texas works.”
