While working on a unique lithium-germanide battery, Pacific Northwest National Laboratory (PNNL) researchers knew something was happening inside the battery to dramatically increase its energy storage capacity, but they couldn’t see it. With no way to analyze the reaction occurring, the researchers could not understand the process. In order to solve the problem, the researchers developed a novel nuclear magnetic resonance (NMR) technique to allow insight and understanding of the electrochemical reactions taking place in the battery. Essentially, they have developed an NMR “camera.”
In the end, this leaves the scientists with not only a novel lithium-germanide battery with a distinctly high energy density, but also an NMR device that can be used to examine reactions as they happen inside the battery.
This from PNNL:
By using the NMR process to look inside the battery and observe this reaction as it happened, the scientists found a way to protect the germanium from expanding and becoming ineffective after it takes on lithium. The secret proved to be forming the germanium into tiny “wires” and encasing them in small, protective carbon tubes to limit the expansion. This technique significantly stabilizes battery performance. Without embedding germanium in carbon tubes, a battery performs well for a few charging-discharging cycles, but fades rapidly after that. Using the “core-shell” structure, however, the battery can be discharged and charged thousands of times.
Can the United States convert to 100 percent clean, renewable energy by 2050? Stanford University’s Mark Z. Jacobson and U.C. Berkeley’s Mark Delucchi certainly think so. In fact, they’ve laid out a very comprehensive plan to do just that.
The two researchers have recently published a study detailing the viability of the U.S. converting to 100 percent green energy. They’re calling for aggressive changes in both infrastructure and energy consumption on a state-by-state level to achieve this goal. The new study shows that this transition from fossil fuels to renewable resources is not only technically possible with already existing technologies, but it’s also economically feasible.
“The main barriers are social, political and getting industries to change. One way to overcome the barriers is to inform people about what is possible,” Jacobson said. “By showing that it’s technologically and economically possible, this study could reduce the barriers to a large scale transformation.”
Recently, scientists have been looking at the Japanese paper-folding art of origami as inspiration for novel flexible energy-storage technologies. While there have been breakthroughs in battery flexibility, there has yet to be a successful development of stretchable batteries. Now, researchers from Arizona State University have unveiled a way to make batteries stretch, yielding big potential outcomes for wearable electronics.
The Arizona State University research team includes ECS member and advisor of the ECS Valley of the Sun student chapter, Candace K. Chan. Chan and the rest of the team were inspired by a variation of origami called kirigami when developing this new generation of lithium-ion batteries.
According to the researchers, the new battery can be stretched more than 150 percent of its original size and still maintain full functionality.

Each biannual meeting hosts a general student poster session and presents awards representing two categories: electrochemical and solid state science and technology.
Winners (pictured) were honored at the 227th ECS Meeting in Chicago on Wednesday May 27, 2015.
This poster session provides a forum for graduate and undergraduate students to present research results of general interest to ECS. The purpose of this session is to foster promote work in both electrochemical and solid-state science and technology, and to stimulate active student interest and participation in ECS.
Cash prizes are given to the presenting student author on each winning paper; the amounts are awarded at the discretion of the organizers and judges.
Your next chance will be at the 229th ECS Meeting in San Diego. Look for the call for papers soon!
Small-scale device provides easy “plug-and-play” testing of molecules and materials for artificial photosynthesis and fuel cell technologies. Image: Joint Center for Artificial Photosynthesis
Scientists have developed a small-scale device that can aid in the advancement of artificial photosynthesis and fuel cell technologies.
The new device provides an easy “plug-and-play” microfluidic test-bed to evaluate materials for electrochemical energy conversion systems. Researchers will now be able to test small amounts of molecules and materials before producing a full-scale device to insure new devices will provide high energy density.
As all functional components in this microfluidic test-bed can be easily exchanged, the performance of various components in the integrated system can be quickly assessed and tailored for optimization. The initial experiments and modeling were performed for water electrolysis; however, the system can be readily adapted to study proposed artificial photosynthesis and fuel cell technologies.
The researchers believe that this technology will be easily adaptable to other technologies, such as solar-fuel generators. Development of such devices may significantly accelerate due to the new ability to assess performance at an early stage.
Wind energy has seen a lot of positive momentum over the past few years in a global effort to help facilitate change in the energy infrastructure. With over $100 billion invested in wind energy in 2014 alone, this technology is one of the fastest growing sectors in the world. Today we’re celebrating Global Wind Day by looking at the innovation that has happened in this sector and taking a peek at what is yet to come.
Over the years, wind energy has seen some dramatic changes. In the 1980s, California was the hub of all wind energy with 90 percent of the world’s installed wind energy capacity. Now, countries such as China, Germany, Spain, India, and the United States have all shifted a substantial percentage of energy needs toward wind. In just a short 12-year period between 2000 and 2012, wind energy has increased over 16 times to more than 282,000 MW of operating wind capacity.
Scientists across the globe are continuing to tap into this technology in order to produce higher efficiency levels at lower price points. Take a look at the work some of our scientists are doing in the sector:
“If you want innovation, if you want to have engineers of tomorrow, you have to have science.”
Those were the words of Bill Nye the Science guy at the 2015 Toshiba/NSTA ExploraVision K-12 national science competition.
A group of students from West Salem High School in Oregon took first place overall in the competition this year with their prototype of programmable bio-scaffolding that could eliminated uncontrollable bleeding from open wounds in those who take blood thinning medications.
Nye has been involved with this competition for more than a decade. Not only does Nye hope that this competition will help encourage young people to value the importance of the sciences, but that it will also highlight the need for gender inclusion in STEM.
“Half the humans are girls and women, so we want half the engineers and scientists to be girls and women,” said Nye.
“The Big Bang Theory” is making history by creating the first television-inspired scholarship to help advance students in STEM.
Students pursing science, technology, engineering, and math degrees at UCLA are eligible for the scholarship, which is currently endowed at $4 million.
“We have all been given a gift with ‘The Big Bang Theory,’ a show that’s not only based in the scientific community, but also enthusiastically supported by that same community. This is our opportunity to give back,” said series creator Chuck Lorre.
This from UCLA:
For the 2015–16 academic year, 20 Big Bang Theory scholars will be selected to receive financial assistance. Each year in perpetuity, five additional scholars will be chosen. Scholarships will be awarded based on financial need to low-income students who have earned admission to UCLA based on academic merit but need additional support to bridge the gap between typical levels of financial aid and the cost of attendance.
Printing technologies in an atmospheric environment offer the potential for low-cost and materials-efficient alternatives for manufacturing electronics and energy devices such as luminescent displays, thin-film transistors, sensors, thin-film photovoltaics, fuel cells, capacitors, and batteries. Significant progress has been made in the area of printable functional organic and inorganic materials including conductors, semiconductors, and dielectric and luminescent materials.
These new printable functional materials have and will continue to enable exciting advances in printed electronics and energy devices. Some examples are printed amorphous oxide semiconductors, organic conductors and semiconductors, inorganic semiconductor nanomaterials, silicon, chalcogenide semiconductors, ceramics, metals, intercalation compounds, and carbon-based materials.
A special focus issue of the ECS Journal of Solid State Science and Technology was created about the publication of state-of-the-art efforts that address a variety of approaches to printable functional materials and device. This focus issue, consisting of a total of 15 papers, includes both invited and contributed papers reflecting recent achievements in printable functional materials and devices.
The topics of these papers span several key ECS technical areas, including batteries, sensors, fuel cells, carbon nanostructures and devices, electronic and photonic devices, and display materials, devices, and processing. The overall collection of this focus issue covers an impressive scope from fundamental science and engineering of printing process, ink chemistry and ink conversion processes, printed devices, and characterizations to the future outlook for printable functional materials and devices.
