The Electrochemical Society’s Stephen Harris, along with a team of researchers from  Berkeley Lab, have found a possible avenue to a better electrolyte for lithium-ion batteries.

Harris – an expert on lithium-ion batteries and chemist at Berkeley Lab’s Materials Science Division – believes that he and his team have unveiled something that could lead to applying lithium-ion batteries to large-scale energy storage.

Researchers around the world know that in order for lithium-ion batteries to store electrical energy for the gird or power electric cars, they must be improved. The team at Berkeley decided to take on this challenge and found surprising results in the first X-ray absorption spectroscopy study of a model lithium electrode, which has provided a better understanding of the liquid electrolyte.

Previous simulations have predicted a tetrahedral solvation structure for the lithium-ion electrolyte, but the new study yields different results.

A new study shows remarkable parallels between hydrogen and graphene under extreme pressures.

The study was conducted by Carnegie’s Ivan Naumov and Russell Hemley, and can be found in the December issue of Accounts of Chemical Research.

Because of hydrogen’s simplicity and abundance, it has long been used as a testing ground for theories of the chemical bond. It is necessary to understand chemical bonding in extreme environments in order to expand our knowledge of a broad range of conditions found in the universe.

It has always been difficult for researchers to observe hydrogen’s behavior under very high pressure, until recently when teams observed the element at pressures of 2-to-3.5 million times the normal atmospheric pressure.

Under this pressure, it transforms into an unexpected structure that consists of layered sheets, rather than close-packed metal – which had been the prediction of scientists many years ago.

Hard-work and perseverance have paid off for The Electrochemical Society’s Telpriore “Greg” Tucker. From chemist, to mentor, to entrepreneur—the Arizona State University doctoral graduate aims to make an impact in renewable energy and transportation.

With his new degree in hand, Tucker plans to revisit his business plans for The Southwest Battery Bike Company, which focuses on developing electric bicycles that can provide a more affordable and greener source of transportation.

“I’ve always had an interest in transportation and how to make it more affordable and sustainable for the public,” Tucker says. “Since my degree focuses on batteries for renewable energy purposes, I began to see a lot of applications from my research. Some of the best jobs can spring from your hobby or projects that you enjoy doing.”

Helping Medicine with Graphene Quantum Dots

Researchers from the University of Sydney have recently published their findings that quantum dots made of graphene can improve bio-imaging and LEDs.

The study was published in the journal Nanoscale, where the scientists detailed how activating graphene quantum dots produced a dot that would shine nearly five times bright than the conventional equivalent.

Essentially, the dots are nano-sized semiconductors, which are fluorescent due to their surface properties. However, this study introduces the utilization of graphene in the quantum dot, which produces an extra-bright dot that has the potential to help medicine.

The Electrochemical Society’s Vilas Pol, along with a team of Purdue University researchers, has developed a nanoparticle network that could produce very fast-charging batteries.

This new electrode design for lithium-ion batteries has been shown to potentially reduce the charging time from hours to minutes, all by replacing the conventional graphite electrode with a network of tin-oxide nanoparticles.

This from Purdue University:

The researchers have performed experiments with a “porous interconnected” tin-oxide based anode, which has nearly twice the theoretical charging capacity of graphite. The researchers demonstrated that the experimental anode can be charged in 30 minutes and still have a capacity of 430 milliamp hours per gram (mAh g−1), which is greater than the theoretical maximum capacity for graphite when charged slowly over 10 hours.

The Electrochemical Society’s Chanyuan Liu, along with a team of University of Maryland researchers, believe they have developed a structure that could bring about the ultimate miniaturization of energy storage components.

The tiny structure, known as the nanopore, includes all the components of a battery and can be fully charged in 12 minutes and recharged thousands of times.

This from University of Maryland:

The structure is called a nanopore: a tiny hole in a ceramic sheet that holds electrolyte to carry the electrical charge between nanotube electrodes at either end. The existing device is a test, but the bitsy battery performs well.
