UMERC's Advanced Energy Storage Technology Selected by NASA

August 12, 2014

Energy Research Center faculty, Eric Wachsman, Liangbing Hu, and Chunsheng Wang have been awarded funding from NASA for their Garnet Electrolyte Based Safe, Lithium-Sulfur Energy Storage technology. NASA has selected this research proposal as a potentially breakthrough technology to power future space missions.

This research is an extension of the team’s existing battery project, funded by the U.S. Department of Energy Advanced Research Projects Agency - Energy (ARPA-E), which focused on energy storage using solid-state electrolytes. The solid-state lithium-ion battery with ceramic electrolyte has a greater abuse tolerance than liquid-based batteries, which allows these batteries to be lighter and have a longer life. The solid-state construction also makes these batteries non-flammable and intrinsically safer than typical liquid-based lithium-ion batteries.

The research funded by NASA will utilize a sulfur cathode to increase the battery capacity. This research aims to increase the energy and power density of storage technology, so that NASA space missions can have more power for longer missions, with minimal mass.

NASA is investing in the development of new energy storage devices that will help enable future robotic and human-exploration missions. Spurred on by the National Research Council report, "NASA Space Technology Roadmaps and Priorities”, these technologies will provide NASA with improved energy generation and storage “with reliable power systems that can survive the wide range of environments unique to NASA missions." NASA believes these awards will lead to such energy breakthroughs.

"NASA's advanced space technology development doesn't stop with hardware and instruments for spacecraft," said Michael Gazarik, associate administrator for Space Technology at NASA Headquarters in Washington. "New energy storage technology will be critical to our future exploration of deep space -- whether missions to an asteroid, Mars or beyond. That's why we're investing in this critical mission technology area."

NEES EFRC Awarded Renewal Funding

June 18, 2014

WASHINGTON -- The University of Maryland's NanoStructures for Electrical Energy Storage is one of just 200 proposals to be awarded a grant by U.S. Energy Secretary Ernest Moniz today.

The research supported by this initiative will enable fundamental advances in energy production, storage, and use. In the case of the University of Maryland's NEES, the research will aim to explore the nanoscience and engineering that will help improve battery storage, cycling, and capacity.

"NEES' vision is a new generation of much better batteries - powerful and long-lasting because they are based on carefully designed nanostructures. This requires that we understand: how to precisely control the multiple components (materials and shapes) of the nanostructures; how to densely pack and connect the nanostructures; how they behave – individually and collectively – during charging and discharging, and why; and how to make them safe and long-lasting over thousands of charging cycles," said NEES director and materials science professor Gary Rubloff. "The NEES mission is to provide the scientific insights and design principles needed to achieve this vision."

"Today, we are mobilizing some of our most talented scientists to join forces and pursue the discoveries and breakthroughs that will lay the foundation for our nation's energy future," Secretary Moniz said. "The funding we're announcing today will help fuel scientific and technological innovation."

Ten of the 32 projects receiving funding projects are new while the rest, such as NEES, received renewed funding based both on their achievements to date and the quality of their proposals for future research.

Since their establishment by the Department’s Office of Science, the EFRCs have produced 5,400 peer-reviewed scientific publications and hundreds of inventions at various stages of the patent process. EFRC research has also benefited a number of large and small firms, including start-up companies.

The centers selected for the second round of funding will help lay the scientific groundwork for fundamental advances in solar energy, electrical energy storage, carbon capture and sequestration, materials and chemistry by design, biosciences, and extreme environments.

Siwy named 2013 APS Fellow

Cutting-edge nanoscience researcher honored

The latest class of Fellows of the American Physical Society includes Zuzanna Siwy, a senior investigator in Nanostructures for Electrical Energy Storage (NEES), an Energy Research Frontier Center funded by the U.S. Department of Energy and headed by University of Maryland Prof. Gary Rubloff.

Siwy, a professor at the University of California, Irvine, was named a fellow “for her innovative use of nanopores in the development of biosensors and nanofluidic ionic circuits." Siwy’s research on nanopores for electronic circuits was a critical contribution to the NEES project, which has just finished its fourth year of operation (

Election to APS Fellow status requires “exceptional contributions to the physics enterprise; e.g., outstanding physics research, important applications of physics, leadership in or service to physics, or significant contributions to physics education. Fellowship is a distinct honor signifying recognition by one's professional peers,” the society’s website says.

Each nomination is evaluated by the Fellowship committee of the appropriate APS division, topical group or forum and is approved by the APS council. Siwy was one of eight honorees by the society’s Division of Biological Physics in 2013.

Added Molecules Allow Metal-Organic Frameworks to Conduct Electricity

From NIST Tech Beat: December 5, 2013

Scientists from Nanostructures for Electrical Energy Storage, a DOE Energy Frontier Research Center, have added something new to a family of engineered, high-tech materials called metal-organic frameworks (MOFs): the ability to conduct electricity. This breakthrough—conductive MOFs—has the potential to make these already remarkable materials even more useful, particularly for detecting gases and toxic substances.

Electron-sharing TCNQ molecules bind to the copper ions in the framework to enable electrical conductivity in MOF materials. The dotted white arrows illustrate the mechanism of electrical conductivity in these materials. (TCNQ: 7,7,8,8-tetracyanoquinododimethane)

MOFs are three-dimensional crystalline materials with nanoscale pores made up of metal ions linked by various organic molecules. MOFs have huge surface areas, and scientists can easily control the size of their pores and how the pores interact with molecules by tinkering with their chemistries. These characteristics make them ideal for use as catalysts, membranes or sponges for gas storage or for drug delivery, among other applications.

Thousands of new MOF structures are discovered and characterized each year. While they come in a dizzying array of chemistries and structures, none of them conducts electricity well. The NIST/Sandia team developed a method to modify the electrical conductivity of MOF thin films and to control it over six orders of magnitude. Their findings will appear in the journal Science.*

"MOFs are typically extremely poor electrical conductors because their constituent building blocks, the organic linkers and the metal ions, don't really talk to each other in terms of electrical conduction," says NIST materials engineer Andrea Centrone. "Our work points to a way of controlling and increasing their conductivity."

The group accomplished this by "infiltrating an insulating MOF with redox-active, conjugated guest molecules."

In other words, they infused and bound electron-sharing molecules into MOF thin films to create a material that is stable in air and approximately a million times more conductive than the unaltered MOF.

"Based on several spectroscopic experiments, we believe that the guest molecules serve two important purposes: they create additional bridges between the metal ions—copper, in this case—and they accept electrical charge," says NIST chemist Veronika Szalai.

According to NIST physicist Paul Haney, who provided some modeling for the experimental data, the arrangement of the guest molecules in the MOF creates a unique conductivity mechanism while preserving the benefits of the porous MOF crystalline structure.

These porous and conductive MOFs may be the first in an entirely new class of materials that could be used for sensing, conformal electronics (electronics that can bend and conform to unusual shapes), and other as-yet-unknown applications.

"Our discovery gives chemists and engineers a whole new degree of freedom to tailor these materials for their technological applications," says Centrone. "I would not be surprised if solar cells could be made using this new class of materials."
