Using sand to improve battery performance

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.

 

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

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.

Mantis Shrimp, Toucan and Trilobite, Oh My

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.

Cheryl Hayashi, a professor of biology at UC Riverside

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.
