A research lab at the University of Houston has developed a new type of material for sodium-ion batteries that could make them more efficient and boost their energy performance.

Led by Pieremanuele Canepa, Robert Welch assistant professor of electrical and computer engineering at UH, the Canepa Research Laboratory is working on a new material called sodium vanadium phosphate, which improves sodium-ion battery performance by increasing the energy density. Energy density is the amount of energy stored per kilogram, and the new material can do so by more than 15 percent. With a higher energy density of 458 watt-hours per kilogram — compared to the 396 watt-hours per kilogram in older sodium-ion batteries — this material brings sodium technology closer to competing with lithium-ion batteries, according to the researchers.

The Canepa Lab used theoretical expertise and computational methods to discover new materials and molecules to help advance clean energy technologies. The team at UH worked with the research groups headed by French researchers Christian Masquelier and Laurence Croguennec from the Laboratoire de Reáctivité et de Chimie des Solides, which is a CNRS laboratory part of the Université de Picardie Jules Verne, in Amiens France, and the Institut de Chimie de la Matière Condensée de Bordeaux, Université de Bordeaux, Bordeaux, France for the experimental work on the project.

The researchers then created a battery prototype using the new materia sodium vanadium phosphate, which demonstrated energy storage improvements. The material is part of a group called “Na superionic conductors” or NaSICONs, which is made to let sodium ions move in and out of the battery during charging and discharging.

“The continuous voltage change is a key feature,” Canepa says in a news release. “It means the battery can perform more efficiently without compromising the electrode stability. That’s a game-changer for sodium-ion technology.”

The synthesis method used to create sodium vanadium phosphate may be applied to other materials with similar chemistries, which could create new opportunities for advanced energy storage. A paper of this work was published in the journal Nature Materials.

"Our goal is to find clean, sustainable solutions for energy storage," Canepa adds. "This material shows that sodium-ion batteries can meet the high-energy demands of modern technology while being cost-effective and environmentally friendly."

Rice names new leader for prestigious nanotechnology, materials science institute

take the lead

A distinguished Rice University professor has assumed the reins of a unique institute that focuses on research within nanoscience, quantum science, and materials science.

Junichiro Kono has assumed leadership of the Smalley-Curl Institute, which houses some of the world’s most accomplished researchers across fields including advanced materials, quantum magnetism, plasmonics and photonics, biophysics and bioengineering, all aspects of nanoscience and nanotechnology, and more.

“With his great track record in fostering international research talent — with student exchange programs between the U.S., Japan, Taiwan, China, Singapore and France that have introduced hundreds of students to new cultures and ways of researching science and engineering — Jun brings a wealth of experience in building cultural and technological ties across the globe,” Ramamoorthy Ramesh, executive vice president for research, says in a news release.

Kono is the Karl F. Hasselmann Professor in Engineering, chair of the Applied Physics Graduate Program and professor of electrical and computer engineering, physics and astronomy and materials science and nanoengineering, and is considered a global leader in studies of nanomaterials and light-matter interactions. He currently leads Rice’s top 10-ranked Applied Physics Graduate Program.

Under his leadership, the program is expected to double in size over. By 2029. The Smalley-Curl Institute will also add additional postdoctoral research fellowships to the current three endowed positions.

The Smalley-Curl Institute is named for Nobel Laureates Richard Smalley and Robert Curl (‘54). Earlier in his career, Kono once worked with Smalley on the physical properties of single-wall carbon nanotubes (SWCNTs), which led to the experimental discovery of the Aharonov-Bohm effect on the band structure of SWCNTs in high magnetic fields.

“I am deeply honored and excited to lead the Smalley-Curl Institute,” Kono says in a news release. “The opportunity to build upon the incredible legacy of Richard Smalley and Robert Curl is both a privilege and a challenge, which I embrace wholeheartedly. I’m really looking forward to working with the talented researchers and students at Rice University to further advance our understanding and application of nanomaterials and quantum phenomena. Together, we can accomplish great things.”

Kono succeeds Rice professor Naomi Halas as director of the institute. Halas is the Stanley C. Moore Professor of Electrical and Computer Engineering and the founding director of the Laboratory for Nanophotonics.

CenterPoint gets $50M DOE grant to improve Houston power grid

grid grant

A $50 million federal grant will help Houston-based CenterPoint Energy strengthen Houston’s power grid.

The U.S. Department of Energy (DOE) grant will support power substation upgrades in the Houston area.

“Our mission is to build the most resilient coastal grid in the nation for the 2.9 million customers we proudly serve in the greater Houston area … [The grant] will directly fund industry-leading technology improvements that are expected to strengthen resiliency, reliability, and meet the growing energy needs of our region,” Jason Ryan, CenterPoint Energy’s executive vice president for regulatory services and government affairs, said in a release.

CenterPoint says the project will make it one of the first U.S. utilities to install Siemens Energy’s grid-stabilizing technology.

The project will create more than 500 construction and installation jobs, CenterPoint says.

“Generations of CenterPoint customers and families in the region will benefit from the advanced technology this grant is funding,” said Kathleen Jackson, a member of the Public Utility Commission of Texas. “And any time companies make improvements like this to their systems, the long-term impact is making the entire grid stronger for Texans.”

The $176.7 million substation project is part of CenterPoint’s Greater Houston Resiliency Initiative, which launched in 2024.

So far, the initiative has:

  • Installed nearly 82,400 storm-resilient poles and equipment
  • Trimmed and cleared more than 13,700 miles of trees and vegetation near power lines
  • Added nearly 820 grid automation and intelligence devices
  • Put more than 880 miles of power lines underground

The initiative kicked off three years after Winter Storm Uri. CenterPoint received harsh criticism for what customers complained was the utility’s slow response to the 2021 storm. Uri caused a massive power outage and at least 246 deaths across Texas.

CenterPoint blamed the Electric Reliability Council of Texas (ERCOT), which operates the power grid for most Texans, for not supplying the utility with enough electricity during and after the storm.
