With the newly popular hoverboards bursting into flames, safety in batteries has made its way to the public spotlight. To increase lithium ion battery safety, one ECS member is working to develop batteries with built in sensors to warn users of potential problems.

Chao-Yang Wang, 19-year ECS member, is taking on the challenge of making the highly popular lithium ion battery safer in light of demands for smaller, more energy efficient devices.

“Li-ion batteries essentially provide portable power for everything,” says Wang. “Your cell phone charge can now last for a week instead of a day, but it’s still the same size. The battery has a lot more energy density, you are compressing more and more energy into a smaller space, and you have to be careful when you do that. Our job is to come up with solutions to provide safety while at the same time increasing performance.”

While lithium ion batteries are typically safe under normal conditions, the battery’s flammable electrolyte solution could overheat and catch fire if it is punctured or overcharged.

Understanding Corrosion from Nano to Macro

From oil pipeline breaks to leaks in chemical plants, corrosion is one of the most damaging and costly naturally occurring events seen today. In order to better understand and prevent to corrosion process, John Scully, ECS member since and 2016 winner of the Society’s Linford Award, has teamed up with a multidisciplinary team to understand corrosion from the nano to the macroscale.

A new Multidisciplinary University Research Initiative (MURI) has emerged with the mission of preventing corrosion. Sponsored by the Office of Naval Research, the ultimate goal of the project is to understand, predict, and control the role of minor elements on the early stages of corrosion in metal alloys.

At its core, corrosion is the degradation of materials due to electrochemical reactions with the environment. In addition to yielding safety issues, corrosion costs an expected $23 billion annually, according to the Department of Defense.

Not only can corrosion cause buildings and bridges to collapse, but corrosion o electrical outlets and medical implants can cause fires and blood poisoning.

In order to address this complex problems, Scully and others are creating a team comprised of those versed in electrochemistry, microscopy, tomography, and simulations.

Robert Savinell, editor of the Journal of The Electrochemical Society

Since 1902, ECS’s flagship journal—the Journal of The Electrochemical Society (JES) originally published as Transactions of The Electrochemical Society—has published some of the best and most innovative research in the field of electrochemical science and technology.

With a historical tradition of scientific excellence and commitment to the pursuit and open exchange of scientific knowledge, JES has accumulated papers through the years that have long-lasting merit. In an effort to preserve the voices of distinguished scientists and engineers who have helped shape our world, the Society implemented the ECS Digital Library Leadership Collection.

Robert Savinell, professor at Case Western Reserve University, is one of the newest faces to conserve this highly significant research. Through a generous gift to the ECS Digital Library, The Robert F. Savinell Collection has been established and the Society has taken yet another step toward its commitment to open access publishing.

Preserving the science of the past

“Most of the papers that get published in the ECS journals have long-lasting value,” says Savinell, editor of JES. “They’re more than just recent news blurbs that introduce a new idea that in a few years will fade away.”

Through a strong editorial and peer-review process, the papers published in JES are not only topically relevant when they are published, but also carry a fundamental insight that applies more broadly than their specific application.

“I think there’s a lot of value in that kind of information that’s being archived forever,” Savinell says.

Beyond the preservation of these timeless voices, Savinell’s gift to the leadership collection supports ECS’s commitment to open access publishing—something Savinell sees as the ultimate future of scholarly publications.

Solar Geoengineering and Climate Change

The Earth is getting warmer and greenhouse gas emissions are on the rise. With carbon dioxide levels at their highest in 650,000 years, scientists across the global are grappling with the question of how to stop global warming.

For many, alternative energy sources are the answer. While the implementation of this technology is crucial for the development of a carbon-free society, flipping the grid is easier said than done. The U.S. alone is highly dependent on fossil fuels, which emit high level of greenhouse gases. Additionally, transitioning the grid to 100 percent renewables would not fully solve the issue. Emissions will still exist in the atmosphere, with warming happening right now.

“When people emerge from poverty and move toward prosperity, they consume more energy,” said Adam Heller in a recent plenary lecture.

The Need for a Solution

Currently, 13 percent of carbon dioxide emissions stem from two industries: steel and cement. According to Heller, these industry are directly correlated to global wealth—what he deems the driving force of acceleration in climate change. To put that in perspective, the solar energy technology that is currently in place in the U.S. saves only 0.3 percent through the use of solar energy, according to Heller. With carbon dioxide emissions constantly accelerating, increasing by 2 percent every year, scientists are looking for solutions to this pressing issue.

“This will lead to a catastrophe,” Heller said. “The question is, what do we do about this catastrophe?”

For Heller and other scientists, part of the answer lies in solar geoengineering (SGE).

“We need to learn something about geoengineering,” Heller said. “We need to learn something about reflecting light from the sun through aerosols in the atmosphere.”

ICYMI: Find other ECS researchers are doing in the world of nanocarbons.

Bor-Yann-LiawBor Yann Liaw is a respected battery-related researcher, working in advanced power sources and energy storage systems at the Hawaii Natural Energy Institute. He has recently been appointed to the ECS Electrochemical Science & Technology (EST) Editorial Board as an Associate Editor for a two year-term, concentrating in Batteries & Energy Storage.

What do you hope to accomplish in your new role as the EST Editorial Board Assistant Editor?
I think that the impact of the journal is very high, but we need to have more people get involved. I am hoping to promote high-quality papers to be submitted to the journal and be part of the effort to promote the awareness of the journal.

What type of expertise do you bring?
I’ve been working in this area for about three decades, so I think that I have enough knowledge between the newer developments of materials, especially in the nano area, versus the most traditional and classic framework of electrochemistry. We’ll see whether we can bridge the technology gap between the two sets of skills into a more coherent framework, so we understand how the materials in a nanoscale can relate to the classical models or understandings for the electrochemistry.

What are the practical applications regarding your research in sugar-air batteries?
Recently we were working with farmers in Hawaii. We have a lot of papaya that are not marketable, which means they look ugly and are not really sellable. We can take those papaya and grind them up and take the juice and put it into a battery and it’s worked like a charm.

What initially got you interested in science?
My parents are both teachers, so I was inspired in the teaching and the education of possibilities of science. Another thing is probably more with my personality. I’m interested in exploring everything that occurs in our daily lives.

What is the biggest challenge going forward for clean energy?
We probably have to come back to more fundamental understandings and make things much easier and simpler so the cost can come down and the impact to the environment can be drastically reduced.

PEFC 15 Student Poster Awards

PEFC-postersThe PhD Student Poster Awards of the PEFC 15 Symposium held at the 228th ECS Meeting in Phoenix, AZ, Oct. 2015 were presented to (pictured left to right) Shuntaro Takahashi (Tohoku University, Japan), Yuji Chino (Yamanashi University, Japan), and Peter Dudenas (Lawrence Berkeley National Lab) for their excellent scientific contributions in the field of Polymer Electrolyte Fuel Cell Research.

Some people strive to continue family tradition, while others prefer to cut their own path. Patrick Linford, grandson of prestigious electrochemist Henry Linford, happens to be stepping into his grandfather’s shoes merely by coincidence.

“If you’d rewind my life to last year, I had no idea what electrochemistry actually was,” says Linford.

Linford, current graduate student at the Massachusetts Institute of Technology (MIT) and U.S. Army Officer, was always fascinated by science and the technical side of things. Despite Linford’s grandfather dying a few years before his birth, their academic and career paths have many similarities.

More Sustainable Energy

Currently, Linford is conducting research in alternative energy—specifically, thermogalvanic batteries to power wireless sensors using waste heat.

“This work has tremendous applications in both the military realm and on the civilian side,” says Linford.

On a global scale, carbon dioxide (CO2) is the number one contributor to dangerous greenhouse gas emissions. Increasing levels of CO2 accelerate the devastating effects of climate change, such as rising sea levels and a higher global temperature. In order to reduce these emissions, researchers are tackling projects from the implementation of a clean energy infrastructure to scrubbing CO2 from the atmosphere. The researchers from the University of South Carolina are exploring even another innovative way to reduce CO2 emissions by turning the harmful byproduct into fuel.

The team, led by ECS member Xiao-Dong Zhou, is looking for a way to harness CO2 emissions that already exist in the environment and use green technologies to inject energy and produce fuel.

Making Green Fuels

While 100 percent renewable energy may be the ultimate answer for the energy infrastructure, it is difficult for industrialized countries that heavily depend on traditional combustion technologies to make that transition so rapidly. The implementation of wind and solar technologies on the large scale also raises question to grid efficiency, reliability, and storage.

One solution to this issue is by using technologies such as solar and wind to turn harmful CO2 emissions into clean, usable fuels.

With collaboration opportunities and innovative workshops, the newly established UCLA student chapter is providing both social and academic experiences for those involved.

Since its approval at the 228th ECS Meeting, the UCLA student chapter has been hard at work creating a robust, multifaceted group where students from all areas of electrochemical science can come together.

“Science, at the entry level, progresses much more efficiently when there is an open dialogue between researchers,” says John Cook, chair of the UCLA student chapter. “Electrochemical science cannot be done alone in a dark room.”

Cook and a collaborator began developing the UCLA student chapter very organically, with the idea that there needed to be a way to bring together the many groups across the campus working in electrochemistry. For Cook, establishing an ECS student chapter was the perfect solution.

“Our main goal is to bring people from different departments together to share ideas,” says Cook. “We want to create an environment in which chemists, engineers, physicists, and even business majors collaborate and share ideas.”
