Scientists around the world are marking 2025 as the “Year of Quantum,” recognizing a century since the birth of modern quantum mechanics and the potential for quantum science and engineering to yield breakthroughs in high-performance computing, communication technology, cybersecurity, medical imaging, environmental sensing and more. 

The Quantum Initiative at Florida State University aims to further quantum science and engineering (QSE) and to realize its potential for transforming technology and our understanding of how to apply these new technologies to improve our world.  

FSU has made major investments in expanding its existing research in this rapidly growing field. At the university’s 2023 quantum symposium, FSU President Richard McCullough announced an initial investment of more than $20 million into the initiative. Two years later, the university has hired seven new faculty members and 11 postdoctoral fellows and has opened a new $126 million cutting-edge laboratory space where faculty and researchers can develop the next generation of quantum science and engineering. 

“Florida State University is a national leader in quantum research,” McCullough said. “Quantum science and engineering will change the world and transform lives and FSU plans to lead the way.” 

NEW FACULTY AND FACILITIES
People are the centerpiece of the university’s efforts in quantum science and engineering. The university is investing in existing faculty and adding new researchers to support groundbreaking QSE research. Investment by FSU leadership has allowed the university to attract some of the best young talent in this field. 

“We are deeply committed to becoming a global leader in key research areas, building on the exceptional foundation laid by our outstanding faculty,” said Vice President for Research Stacey S. Patterson. 

Along with new hires, support from the Florida Legislature has allowed FSU to develop the facilities that will enable scientists to break new ground in quantum research. 

The Interdisciplinary Research and Commercialization Building (IRCB) will be a hub for researchers from a variety of disciplines and serve as the headquarters for FSU Quantum. With state-of-the-art equipment and remarkable faculty talent, FSU leadership envisions the IRCB as a regional focal point for quantum science and engineering, drawing researchers from around the Southeast who may use the equipment for their own projects.

You’ve probably experienced the dread of a suddenly dead phone that is glacially slow to recharge. Earbuds or laptops that die at the most inconvenient times. And perhaps you’ve delayed shopping for an electric car because of limited cruise range (or high price). These battery breakdowns and charge collapses are because of shortcomings in the lithium-ion batteries powering today’s technology.

But recent research at the Florida State University headquartered National High Magnetic Field Laboratory is advancing work on a new, better type of battery.

Scientists are looking to transition from the liquid-electrolyte-based lithium-ion batteries that have powered our devices for the past 30 years to solid-state systems capable of meeting the needs of the next generation of electronics. Solid-state batteries are safer, reducing the chances of a fire when a battery is damaged, has short circuits, or is overheated. And solid-state batteries also offer higher energy densities and longer battery life.

“Right now, maybe you notice with your iPhones, or with your tablets, they do have a set amount of time before the battery depletes or before you have to change to a new one. Ideally, for the all-solid-state batteries, they can last longer,” said FSU doctoral student Erica Truong.

But a major drawback has kept solid-state batteries from wider use. They are expensive to produce and difficult to manufacture in large numbers.

Truong is on the research team of Florida State University chemistry and biochemistry professor Yan-Yan Hu, working to develop solid-state battery systems that improve performance and are commercially viable.

“In this study, we looked at a new solid electrolyte design that can be generally applied to other systems to help improve their performance,” Truong said.

Electrolytes serve as a crucial component in batteries, acting as a separator between the cathode (or the negative terminal) and anode (or positive terminal). They facilitate the movement of ions between the electrodes, enabling the battery to charge when connected to a power supply or to supply power when linked to a device such as a phone.

The FSU team analyzed the structures and properties of a promising electrolyte made of lithium chloride and gallium fluoride. They discovered a strategy that can effectively promote ion transport in solid electrolytes.

Using the MagLab’s solid-state Nuclear Magnetic Resonance systems, the researchers took a detailed look at the gel-like electrolyte’s structural characteristics that contribute to ion transport. The investigation found the chlorine and fluorine combine in something called charge clustering, freeing up the lithium ions.

This translates to fast charging and longer life from the battery.

“The charge-clustering phenomenon helps weaken the bond between the lithium and the other components, so the lithium can move faster, move more efficiently through the electrolyte,” said Truong.

The group’s findings were published in Science Advances.

“What’s also interesting about this material is it’s not purely solid; it’s more clay-like,” said Truong.

That clay-like quality means the material can be shaped and molded to fit any space.

“That could be beneficial because it can incorporate into the battery better, improving contact between electrolyte and electrodes,” Truong explained.

The project was in collaboration with Samsung through its Advanced Institute of Technology, which initially designed and synthesized the lithium-chloride and gallium-fluoride electrolyte in 2021.

Samsung is among the many electronics companies searching for the ideal solid-state battery that boosts performance, improves safety, and can be quickly, cheaply manufactured at scale.

The FSU researchers believe their findings will inspire new frontiers in battery design, including solid-state electrolytes using sodium, calcium, or magnesium, leading to batteries with performance “far exceeding state-of-the-art.”

Development and manufacturing of advanced materials is a top focus of ASPIRE, the new strategic plan from the Florida State University Office of Research.
