New Paper-like Material Could Boost Electric Vehicle Batteries

Researchers create silicon nanofibers 100 times thinner than human hair for potential applications in batteries for electric cars and personal electronics

Mihri and Cengiz Ozkan in their lab

RIVERSIDE, Calif. (www.ucr.edu) — Researchers at the University of California, Riverside’s Bourns College of Engineering have developed a novel paper-like material for lithium-ion batteries. It has the potential to boost by several times the specific energy, or amount of energy that can be delivered per unit weight of the battery.

This paper-like material is composed of sponge-like silicon nanofibers more than 100 times thinner than human hair. It could be used in batteries for electric vehicles and personal electronics.

The findings were just published in a paper, “Towards Scalable Binderless Electrodes: Carbon Coated Silicon Nanofiber Paper via Mg Reduction of Electrospun SiO2 Nanofibers,” in the journal Nature Scientific Reports. The authors were Mihri Ozkan, a professor of Materials Science and Engineering and Electrical and Computer Engineering, Cengiz S. Ozkan, a professor of Materials Science and Engineering and Mechanical Engineering, and six of their graduate students: Zach Favors (MSE), Hamed Hosseini Bay (ME), Zafer Mutlu (MSE), Kazi Ahmed (EE), Robert Ionescu (MSE) and Rachel Ye (ME).

The nanofibers were produced using a technique known as electrospinning, whereby 20,000 to 40,000 volts are applied between a rotating drum and a nozzle, which emits a solution composed mainly of tetraethyl orthosilicate (TEOS), a chemical compound frequently used in the semiconductor industry. The nanofibers are then exposed to magnesium vapor to produce the sponge-like silicon fiber structure.

Conventionally produced lithium-ion battery anodes are made using copper foil coated with a mixture of graphite, a conductive additive, and a polymer binder. But, because the performance of graphite has been nearly tapped out, researchers are experimenting with other materials, such as silicon, which has a specific capacity, or electrical charge per unit weight of the battery, nearly 10 times higher than graphite.

The problem with silicon is that is suffers from significant volume expansion, which can quickly degrade the battery. The silicon nanofiber structure created in the Ozkan’s labs circumvents this issue and allows the battery to be cycled hundreds of times without significant degradation.

This technology also solves a problem that has plagued free-standing, or binderless, electrodes for years: scalability. Free-standing materials grown using chemical vapor deposition, such as carbon nanotubes or silicon nanowires, can only be produced in very small quantities (micrograms). However, Favors was able to produce several grams of silicon nanofibers at a time even at the lab scale.

The researchers’ future work involves implementing the silicon nanofibers into a pouch cell format lithium-ion battery, which is a larger scale battery format that can be used in EVs and portable electronics.

The research is supported by Temiz Energy Technologies. The UC Riverside Office of Technology Commercialization has filed patents for inventions reported in the research paper.




 


Researchers Make Magnetic Graphene

UC Riverside research could lead to new multi-functional electronic devices

Now a team of physicists at the University of California, Riverside has found an ingenious way to induce magnetism in graphene while also preserving graphene’s electronic properties. They have accomplished this by bringing a graphene sheet very close to a magnetic insulator – an electrical insulator with magnetic properties.

“This is the first time that graphene has been made magnetic this way,” said Jing Shi, a professor of materials science and engineering and physics and astronomy, whose lab led the research. “The magnetic graphene acquires new electronic properties so that new quantum phenomena can arise. These properties can lead to new electronic devices that are more robust and multi-functional.”

The finding has the potential to increase graphene’s use in computers, as in computer chips that use electronic spin to store data.

Credit: Mahesh Neupane, Roger Lake, and Alexander Balandin Graphene, a form of carbon in which a single layer of atoms forms a two-dimensional, honeycomb crystal lattice, conducts electricity and heat efficiently and interacts with light in unusual ways. These properties have led to worldwide efforts in exploring its use in electronics, photonics and many other applications.
 

Rapid advances in graphene research during the last decade have suggested tantalizing possibilities for other two-dimensional materials, each of which might have distinct and useful properties.

To investigate the promise of 2-D layered materials beyond graphene, the National Science Foundation's (NSF) Office of Emerging Frontiers in Research and Innovation (EFRI) recently awarded grants totaling close to $18 million. NSF collaborated closely with the Air Force Office of Scientific Research (AFOSR), which is planning to invest an additional $10 million through its Basic Research Initiative.

Over the next four years, nine teams involving a total of 42 researchers at 18 institutions will pursue transformative research in the area of 2-D atomic-layer research and engineering (2-DARE).

EFRI 2-DARE researchers will explore fundamental materials properties, synthesis and characterization, predictive modeling techniques and scalable fabrication and manufacturing methods to create new devices for photonics, electronics, sensors and energy harvesting. They also will investigate forming such devices on flexible, transparent and conformal substrates.

Alexander Balandin of the University of California, Riverside (UCR), will lead the project "Novel Switching Phenomena in Atomic Heterostructures for Multifunctional Applications" (1433395) in collaboration with Alexander Khitun of UCR, Roger Lake of UCR, and Tina Salguero of the University of Georgia.

The EFRI 2-DARE researchers will seek out 2-D layered materials and systems that offer enhanced and new capabilities in thermal storage, thermoelectric performance, gas adsorption and other areas. The rich variety of properties these materials and systems offer potentially can be engineered on demand.

Using sand to improve battery performance

From left, (b) unpurified sand, (c) purified sand, and (d) vials of unpurified sand, purified sand, and nano silicon.
 

Researchers at the University of California, Riverside's Bourns College of Engineering have created a lithium ion battery that outperforms the current industry standard by three times. The key material: sand. Yes, sand.

 
"This is the holy grail -- a low cost, non-toxic, environmentally friendly way to produce high performance lithium ion battery anodes," said Zachary Favors, a Materials Science and Engineering Graduate Student working with Cengiz and Mihri Ozkan, both Materials Science and Engineering professors at UC Riverside.

The idea came to Favors six months ago. He was relaxing on the beach after surfing in San Clemente, Calif. when he picked up some sand, took a close look at it and saw it was made up primarily of quartz, or silicon dioxide.

His research is centered on building better lithium ion batteries, primarily for personal electronics and electric vehicles. He is focused on the anode, or negative side of the battery. Graphite is the current standard material for the anode, but as electronics have become more powerful graphite's ability to be improved has been virtually tapped out.

Researchers are now focused on using silicon at the nanoscale, or billionths of a meter level as a replacement for graphite. The problem with nanoscale silicon is that it degrades quickly and is hard to produce in large quantities.

Favors set out to solve both these problems. He researched sand to find a spot in the United States where it is found with a high percentage of quartz. That took him to the Cedar Creek Reservoir, east of Dallas, where he grew up.

Sand in hand, he came back to the lab at UC Riverside and milled it down to the nanometer scale, followed by a series of purification steps changing its color from brown to bright white, similar in color and texture to powdered sugar.

After that, he ground salt and magnesium, both very common elements found dissolved in sea water into the purified quartz. The resulting powder was then heated. With the salt acting as a heat absorber, the magnesium worked to remove the oxygen from the quartz, resulting in pure silicon.

The Ozkan team was pleased with how the process went. And they also encountered an added positive surprise. The pure nano-silicon formed in a very porous 3-D silicon sponge like consistency. That porosity has proven to be the key to improving the performance of the batteries built with the nano-silicon.

The improved performance could mean expanding the expected lifespan of silicon-based electric vehicle batteries up to 3 times or more, which would be significant for consumers, considering replacement batteries cost thousands of dollars. For cell phones or tablets, it could mean having to recharge every three days, instead of every day.

The findings were just published in the journal Nature Scientific Reports.

Now, the Ozkan team is trying to produce larger quantities of the nano-silicon beach sand and is planning to move from coin-size batteries to pouch-size batteries that are used in cell phones.

The research is supported by Temiz Energy Technologies. The UCR Office of Technology Commercialization has filed patents for inventions reported in the research paper.

“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 innovation.”

He said the intent of the Energy Frontier Research Centers is to make fundamental advances in solar energy, electrical energy storage, carbon capture and sequestration, materials and chemistry by design, biosciences, and extreme environments.

“I am happy to hear the news,” said Shi, the UCR physics professor who has put together an interdisciplinary team of  researchers from UC Riverside, UCLA, Johns Hopkins University, Arizona State University, University of Texas, Austin and Colorado State University, Fort Collins.

“I’m looking forward to seeing the scientific advances that they come up with,” said Michael Pazzani, UC Riverside’s Vice Chancellor for Research and Economic Development. “This is exactly the kind of scientific leadership that UC Riverside has been encouraging and supporting. This project will lay the groundwork for energy technology for the nation.” 

SHINES will investigate several aspects of basic research: new ultrathin films, nanostructured composites, high resolution imaging, the transport of electrical signals, heat and light. “All of it will be studied, modeled and simulated in order to help the nation’s ability to advance in the way we use energy,” said Shi, the lead researcher.

Silly Putty Material Inspires Better Batteries

Engineers use silicon dioxide to make lithium-ion batteries that last three times longer between charges compared to current standard

RIVERSIDE, Calif. (www.ucr.edu) — Using a material found in Silly Putty and surgical tubing, a group of researchers at the University of California, Riverside Bourns College of Engineering have developed a new way to make lithium-ion batteries that will last three times longer between charges compared to the current industry standard.

The team created silicon dioxide (SiO2) nanotube anodes for lithium-ion batteries and found they had over three times as much energy storage capacity as the carbon-based anodes currently being used. This has significant implications for industries including electronics and electric vehicles, which are always trying to squeeze longer discharges out of batteries.

“We are taking the same material used in kids’ toys and medical devices and even fast food and using it to create next generation battery materials,” said Zachary Favors, the lead author of a just-published paper on the research.

The paper, “Stable Cycling of SiO2 Nanotubes as High-Performance Anodes for Lithium-Ion Batteries,” was published online in the journal Nature Scientific Reports.

It was co-authored by Cengiz S. Ozkan and professor, Mihrimah Ozkan, Materials Science and Engineering professosr, and several of their current and former graduate students: Wei Wang, Hamed Hosseinni Bay, Aaron George and Favors.Battery and silcon dioxide sample

Silicon polymer and battery used for the research.

The team originally focused on silicon dioxide because it is an extremely abundant compound, environmentally friendly, non-toxic, and found in many other products.

Silicon dioxide has previously been used as an anode material in lithium ion batteries, but the ability to synthesize the material into highly uniform exotic nanostructures with high energy density and long cycle life has been limited.

Their key finding was that the silicon dioxide nanotubes are extremely stable in batteries, which is important because it means a longer lifespan. Specifically, SiO2 nanotube anodes were cycled 100 times without any loss in energy storage capability and the authors are highly confident that they could be cycled hundreds more times.

The researchers are now focused on developed methods to scale up production of the SiO2 nanotubes in hopes they could become a commercially viable product.

UC Riverside professor to lead team selected for $7.5 million grant to study more than 20 organisms to develop strong, tough materials based on their design structures

 A team of researchers led by a University of California, Riverside Materials david Science and Engineering Associate Professor, David Kisailus, have been selected to receive a $7.5 million Department of Defense grant to uncover fundamental design rules and develop simple and basic scientific foundations for the predictable design of light-weight, tough and strong advanced materials inspired by a wide diversity of structures from plants and animals, including the mantis shrimp, toucan and bamboo.

“We are taking what biological systems have constructed over millions of years and coming up with design rules that nature hasn’t really thought of,” said David Kisailus, the lead researcher on the grant who holds the Winston Chung Endowed Chair of Energy Innovation in the department of Chemical and Environmental Engineering and Materials Science program at the UC Riverside’s Bourns College of Engineering and is a Kavli Fellow of the National Academy of Sciences.

Kisailus assembled the multidisciplinary team, whose six co-principal investigators consist of chemists, materials scientists, mechanical engineers and biologists. They are: Cheryl Hayashi, a professor of biology at UC Riverside; Joanna McKittrick andMarc Meyers, both professors in mechanical and aerospace engineering and the materials science program at UC San Diego;Robert Ritchie, a distinguished professor in materials science and mechanical engineering at UC Berkeley; Pablo Zavattieri, an associate professor of civil and mechanical engineering at Purdue University; and Horacio Espinosa, the James N. and Nancy J. Farley professor in manufacturing & entrepreneurship in mechanical engineering at Northwestern University.

In addition, the team includes collaborators with broad backgrounds. They are Professor Nigel Hughes, a paleobiologist in earth sciences at UC Riverside; Elaine DiMasi of Brookhaven National Laboratory; Rajesh Naik and David Mollenhauer, both of the Air Force Research Laboratory; Brad Hollingsworth of the San Diego Natural History Museum; Gabriel Miller of the San Diego Zoo; and Alan Leukhardt of Safariland, a designer and manufacturer of military, law enforcement and sporting equipment.

The funding, which will be distributed over five years, comes from the Department of Defense Multidisciplinary University Research Initiative (MURI) program. This particular grant, managed by Hugh DeLong, department head of complex materials & devices, comes from the Air Force Office of Scientific Research, one of the military research offices which awards MURI grants.

With the funding the researchers will study more than 20 organisms, including mammals, reptiles, birds, fish, mollusks, crustaceans, insects and plants. Examples include: light-weight, tough and durable materials with cellular structures such as the stem of bamboo; the beak of a toucan; layered structures from shells of marine snails and antlers from mammals; twisted plywood structures found in crustacean structures such as the club of mantis shrimp; and insect cuticles.

These structures are particularly interesting because they are composed of relatively simple biological materials such as keratin found in fingernails, yet display incredible mechanical performance. The team will also reach back in history, looking at dynamic evolutionary processes such as the structure of the extinct trilobite, which existed for more than 200 million years by adapting to its environment.

The research program utilizes four interwoven thrusts, including the ultrastructural and mechanical investigation of these organisms, development of mathematical models of their structures and new design, fabrication of biomimetic structures that emulate features found in both natural systems and theory-based designs in order to underpin their tough, strong structures. Finally, the team will conduct comparative evolutionary analyses to pinpoint design principles that are unique and those, which have arisen convergently.

Michael Pazzani, UC Riverside’s vice chancellor for research and economic development, whose office provided $70,000 in seed funding to Kisailus and Hayashi for their joint research, is pleased that a UC Riverside professor is leading this project with experts from some of the nation’s finest research institutions.

“This multidisciplinary research will highlight the value in biologically-inspired materials allowing the next generation of materials development to take advantage of what nature has known for millennia,” Pazzani said.

UC Riverside Research from MSE Professors Cengiz and Mihri Ozkan featured on Three Journal Covers 

Prof. Mihri Ozkan, Prof. Cengiz S. Ozkan, and co-workers report a new fluorescence quenching microscopy metrology technique that allows the identification of graphene layers and doped/undoped regions across a large graphene landscape by utilizing the fact that undoped regions of graphene quench fluorescence more than the doped regions through resonant energy transfer. Contrast differences in fluorescence across the graphene sheet reveal the complex ring-patterned doping. This metrology technique is well-suited for industrial, large-scale, pristine, and modified graphene sheet surface characterization. Ozkans’ and their co-workers’ related work published as cover articles in high-venue journals: SMALL, NANOSCALE and ADVANCED FUNCTIONAL MATERIALS.

Dr. Balandin's Group Develops Technique to Keep Cool High-Power Semiconductor Devices Used in Wireless Applications, Traffic Lights and Electric Cars

RIVERSIDE, Calif. (www.ucr.edu) — A group of researchers at the University of California, Riverside Bourns College of Engineering have developed a technique to keep cool a semiconductor material used in everything from traffic lights to electric cars.

Gallium Nitride (GaN), a semiconductor material found in bright lights since the 1990s, is used in wireless applications due to its high efficiency and high voltage operation. However, the applications and market share of GaN electronics is limited because it is difficult to remove heat from them.

That could change due to a technique developed by the Nano-Device Laboratory research group led by Alexander Balandin, professor of electrical engineering and founding chair of Materials Science and Engineering program.

The research group demonstrated that hot spots in GaN transistors can be lowered by as much 20 degrees Celsius through the introduction of alternative heat-escaping channels implemented with graphene multilayers, which are excellent heat conductors. The temperature reduction translates to an increase in the lifetime of the device by a factor of 10. Read More in Full UCR News Release

Would a Molecular Horse Trot, Pace, or Glide Across a Surface?

Professor Ludwig Bartels' lab led the research to answer this question.  "Molecular machines can be found everwhere in nature, for example, transporting proteins through cells and aiding metabolism.  To develop artificial molecular machines, scientists need to understand the rules that govern mechanics at the molecular or nanometer scale (a nanometer is a billionth of a meter)."

Balandin Group Demonstrates the First Low-Noise Double-Gate Graphene Transistor

Optical microscopy image of a transistor fabricated by Guanxiong Liu, PhD candidate in Balandin group.Graphene, which consists of just a single atomic layer of carbon atoms bound into crystal lattice, is the hottest new material system considered for applications in future electronics and sensors. The properties, which make graphene so desirable for future electronics, are its extremely high electrical and thermal conductivities. A team of researchers from the University of California - Riverside (UCR) and Rensselaer Polytechnic Institute (RPI) led by UCR electrical engineering professor Alexander Balandin designed, built and demonstrated the double gate graphene transistor, which satisfies the low-noise requirements for practical applications. A top noise expert from the Ioffe Physico-Technical Institute of the Russian Academy of Sciences also participated in the study. The transistors were fabricated at UCR with the electron beam lithography from single atomic layer graphene and had both the "conventional" bottom gate and the top gate separated from the graphene channel by a special gate dielectric. The combined action of both gates allowed the team to investigate the sources of the electronic noise, and to come up with the strategy for its reduction. For any transistor to be useful for communications or information processing, the level of the electronic low-frequency noise has to be reduced to an acceptable level defined by the Hooge parameter. Although modern electronic devices such as cell phones operate at very higher frequencies, the low-frequency noise is extremely important. Due to unavoidable non-linearities in devices, the low frequency noise up-converts to higher frequency, and contributes to the phase noise of the system, thus limiting its performance. The same is true for the proposed applications of graphene as a material for ultra-sensitive detectors. The results obtained at UCR and RPI pave the way for practical applications of graphene. They appear in this week's Applied Physics Letters and featured in nanotechnology media: see, for example, a detail report in Nano Werk and in Nanotechnology Now
