While you may be unfamiliar with Khalil Amine, he has made an immense impact in your life if you happen to use batteries in any way.

As a researcher with a vision of where the science can be applied in the market, Amine has been monumental in developing and moving some of the biggest breakthroughs in battery technology from the lab to the marketplace.

Amine is currently head of the Technology Development Group in the Battery Technology Department at Argonne National Laboratory. From 1998-2008 he was the most cited scientist in the world in the field of battery technology.

He is the chair of the organizing committee for the 18th International Meeting on Lithium Batteries being held this June in Chicago.

Up until the 1948, the lemon-lime soda 7-Up contained lithium salts, a substance most commonly known for its medical qualities used in the treatment of major depressive disorders.

While the additive has long since been removed from 7-Up, the scientists from the YouTube channel Periodic Videos thought it would be interesting to drop a piece of lithium into the current day recipe for the soda.

Initially, the results were as expected: nothing special. But after a few more seconds, the solution began transforming from its clear, bubbly state to a dark, sludgy brown. Watch as Sir Martyn Poliakoff explains the unexpected phenomena.

Advances in Sodium Batteries

With energy demands increasing every day, researchers are looking toward the next generation of energy storage technology. While society has depended on the lithium ion battery for these needs for some time, the rarity and expense of the materials needed to produce the battery is beginning to conflict with large-scale storage needs.

To combat this issue, a French team comprised of researchers primarily from CNRS and CEA is making gains in the field of electrochemical energy storage with their new development of an alternative technology for lithium ion batteries in specific sectors.

Beyond Lithium

Instead of the rare and expensive lithium, these researchers are focusing on the use of sodium ions—a more cost efficient and abundant materials. With efficiently levels comparable to that of lithium, many commercial sectors are showing an increasing interest for sodium’s potential in storing renewable energy.

While this development takes the use of sodium to a new level, the idea has been around since the 1980s. However, sodium never took off as the primary battery building material due to low energy densities and short life cycles. It was then that researchers chose to power electronics with lithium for higher efficiency levels.

A collaborative group of six researchers from Stony Brook University and Brookhaven National Laboratory are using pioneering x-ray techniques to build a better and more efficient battery.

The researchers—four of whom are active ECS members, including Esther Takeuchi, Kenneth Takeuchi, Amy Marschilok, and Kevin Kirshenbaum—have recently published their internal mapping of atomic transformations of the highly conductive silver matrix formation within lithium-based batteries in the journal Science.

(PS: You can find more of these scientists’ cutting-edge research by attending the 228th ECS Meeting in Phoenix, where they will be giving presentations. Also, Esther Takeuchi will be giving a talk at this years Electrochemical Energy Summit.)

This from Stony Brook University:

In a promising lithium-based battery, the formation of a silver matrix transforms a material otherwise plagued by low conductivity. To optimize these multi-metallic batteries—and enhance the flow of electricity—scientists need a way to see where, when, and how these silver, nanoscale “bridges” emerge. In the research paper, the Stony Brook and Brookhaven Lab team successfully mapped this changing atomic architecture and revealed its link to the battery’s rate of discharge. The study shows that a slow discharge rate early in the battery’s life creates a more uniform and expansive conductive network, suggesting new design approaches and optimization techniques.

With the demand for hand-held electronics at an all-time high, the costs of the materials used to make them are also rising. That includes materials used to make lithium batteries, which is a cause for concern when projecting the development of large-scale grid storage.

In order to find an alternative solution to the high material costs connected with lithium batteries, the researchers at the Australian Nuclear Science and Technology Organisation (ANSTO) and the Institute of Physics at the Chinese Academy of Science in Beijing have begun focusing their attention on sodium-ion batteries.

The science around sodium-ion batteries dates back to the 1980s, but the technology never took off due to resulting low energy densities and short life cycles.

However, the new research looks to combat those issues by improving the properties of a class of electrode materials by manipulating their electron structure in the sodium-ion battery.

A New Generation of Electric Car Battery

Scientists out of the University of Waterloo are one step closer to inventing a cheaper, lighter and more powerful rechargeable battery for electric vehicles. At the heart of this discovery lies a breakthrough in lithium-sulfur batteries due to an ultra-thin nanomaterial.

This from the University of Waterloo:

Their discovery of a material that maintains a rechargeable sulfur cathode helps to overcome a primary hurdle to building a lithium-sulfur (Li-S) battery. Such a battery can theoretically power an electric car three times further than current lithium-ion batteries for the same weight – at much lower cost.

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.

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.
