When it comes to energy storage, hydrogen is becoming more and more promising. From hydrogen fuel cell vehicles to the “artificial leaf” to the transformation of waste heat into hydrogen, researchers are looking to hydrogen for answers to the growing demand for energy storage.

At the Lawrence Livermore National Laboratory (LLNL), researchers are using hydrogen to make lithium ion batteries operate longer and have faster transport rates.

In a response to the need for higher performance batteries, the researchers began by looking for a way to achieve better capacity, voltage, and energy density. Those qualities are primarily determined by the binding between lithium ions and electrode material. Small changes to the structure and chemistry of the electrode can mean big things for the qualities of the lithium ion battery.

The research team from LLNL discovered that by subtly changing the electrode, treating it with hydrogen, lithium ion batteries could have higher capacities and faster transport levels.

“These findings provide qualitative insights in helping the design of graphene-based materials for high-power electrodes,” said Morris Wang, an LLNL materials scientist and co-author of the paper.

While we typically work to preserve the environment, there are some aspects that cause more harm than good. Harmful algal blooms (HABs) are one of these environmentally hazardous parts of nature, severely impacting human health, the ecosystem, and the economy.

While HABs put countless people at risk though polluted drinking water, researchers are now attempting to create some good from this negative. Through heating the algal at a very high temperature in argon gas, HABs can be converted into a material known as hard carbon. Typically made from petroleum, hard carbon also has development potential through biomass. Due to the material’s qualities and capabilities, hard carbons have the potential to be used as high-capacity, low-cost electrodes for sodium-ion batteries.

“Harmful algal blooms, caused by cyanobacteria (or so called ‘blue-green algae’), severely threaten humans, livestock, and wildlife, leading to illness and sometimes even death,” says Da Deng, co-author of the recent study. “The Toledo water crisis in 2014 caused by HABs in Lake Erie is a vivid example of their powerful and destructive impact. The existing technologies to mitigate HABs are considered a ‘passive’ technology and have certain limitations. It would significantly and broadly impact our society and environment if alternative technologies could be developed to convert the HABs into functional high-value products.”

From solar energy to biofuels to hydrogen cars—sustainable solutions have become some of the hottest topics in the scientific community. While much of the focus in alternative forms of transportation has been automobiles (see Tesla and Toyota), ECS member Telpriore Gregory Tucker is shifting his attention in another direction: electric bikes. While Tucker’s bikes hold promise for the future of sustainable transportation, they could also potentially have a much greater impact.

“I don’t just sell electric bikes, I actually provide people with sustainable solutions,” says Tucker, founder of the Southwest Battery Bike Co.

Inspiration through education

The idea behind Tucker’s Phoenix, Arizona-based electric bike company started back in 2010 when he began volunteering with the youth at his church. As a mentoring program began to emerge, Tucker volunteered to addresses topics in STEM education.

“One of my personal goals is helping kids. I’ve been in a lot of programs as a child to help me get to where I am now,” says Tucker. “Giving back is important to me because I see a lot of kids in situations I’ve been in or environments that I’ve come from where a lot of the time, you don’t get that opportunity.”

From Doron Aurbach, Technical Editor, Batteries and Energy Storage:

The field of advanced batteries is highly dynamic and important. The development and commercialization of Li ion batteries can be considered one of the most important successes of modern electrochemistry.

This battery technology is now challenged to power electric vehicles. The requirements of high-energy-density drive intensive work on novel battery systems, beyond Li ion technology (Li-sulfur, metal-oxygen batteries and more).

We are proud and happy to publish a special collection of papers on advanced batteries and related research efforts.

Twenty-one experts in the field were asked to submit review/opinion papers on topics related to advanced battery research, based on their experience. We believe that this collection of papers provides our readership an important update and guidelines for further studies and development work.

On the path to building better batteries, researchers have been choosing silicon as their material of choice to increase life-cycle and energy density. Silicon is favored among researchers because its anodes have the ability to store up to ten times the amount of lithium ions than conventional graphite electrodes. However, silicon is a rather rigid material, which makes it difficult for the battery to withstand volume changes during charge and discharge cycles.

This from Georgia Tech:

Using a combination of experimental and simulation techniques, researchers from the Georgia Institute of Technology and three other research organizations have reported surprisingly high damage tolerance in electrochemically-lithiated silicon materials. The work suggests that all-silicon anodes may be commercially viable if battery charge levels are kept high enough to maintain the material in its ductile state.

Chris Johnson, group leader at Argonne National Laboratory and ECS Battery Division vice-chair, we would like to let you know about The 2^nd International Conference on Sodium Batteries, which will take place at the Sheraton Wild Horse Pass Resort and Hotel in Chandler, AZ the week before (Oct. 7 – 9) the ECS meeting this October.

This from Dr. Johnson:

The location and timing for this specialized sodium-only conference was set up to dovetail with the ECS meeting and promote one travel event (particularly for overseas travelers). The conference was established to function as a technical and collaborative forum to bring together technical, policy, and government experts in battery science and engineering, particularly those who specialize in sodium batteries as a next-generation energy storage technology for “Beyond Li-ion” battery chemistries.

The conference’s goal is to communicate a current understanding and benchmark state-of-art science in the field. Research and progress in sodium batteries technology will be discussed by this international community. We expect 100 attendees, who both specialize in pushing this technology forward, but also who want to learn more about emergent technology. Approximately 20 internationally recognized invited speakers will give 30-minute presentations. A poster session will also be held.

The cost to attend is $300 and includes two receptions, and two sit-down/served luncheons. To learn more or register for the conference, please visit the conference homepage.

And don’t forget to check out the ECS Battery Division’s sodium-battery-specific talks scheduled for Sunday afternoon in Phoenix!

Since the 1970s, biomedical engineers have been looking for a way to develop a “smart pill” that can monitor and treat ailments electronically. Since then, breakthroughs such as the camera pill have come about—allowing those in the medical field to perform more complex surgeries and study how drugs are broken down.

While we have biologically understood the concept of edible electronics for some time now, researchers have not been able to nail down the appropriate materials that should be used in such an application as to not cause internal damage.

“Smart Pill” to Sense Problems

Researchers from Carnegie Mellon University are putting fourth their proposal to this question in the journal Trends in Biotechnology, which could yield edible electronic technology that is safe for consumption.

“The primary risk is the intrinsic toxicity of these materials, for example, if the battery gets mechanically lodged in the gastrointestinal tract—but that’s a known risk. In fact, there is very little unknown risk in these kinds of devices,” says Christopher Bettinger, a professor in materials science and engineering and author of the study. “The breakfast you ate this morning is only in your GI tract for about 20 hours—all you need is a battery that can do its job for 20 hours and then, if anything happens, it can just degrade away.”

The technology that was created for sci-fi movies may soon be reality. A new transparent, solar powered lithium ion battery has been developed by a team of researchers from Kogakuin University. Not only could this new battery bring transparent smartphones reminiscent of the Iron Man movies to life, but it could replace any transparent items (i.e. windows) for additional energy storage capabilities.

Since a team of researchers at Stanford University developed the first nearly transparent battery about four years ago, the team at Kogakuin University has been hard at work on their transparent battery that combines clarity with self-charging abilities.

Other researchers have been focusing on the qualities and potential of transparent materials. A team from Michigan State University began exploring this field last year to develop a transparent luminescent solar concentrator that can be used on buildings, cell phones, and other clear surfaces. However, this development did not have the functionality that the new transparent battery from Kogakuin University does.

Batteries are a critical part of our everyday lives. From phones to laptops to cars to grid energy storage—batteries are essential to many devices. Lithium ion batteries have taken the lead in battery technology, with lithium iron phosphate batteries (LFP) performing particularly well. While it was known that LFP batteries could charge quickly and withstand many factors, the reasons for this were unknown until know.

A team of researchers from the Paul Scherrer Institute and Toyota Central R&D Labs has discovered why LFP batteries can be recharged so rapidly. The team is comprised of ECS member Tsuyoshi Sasaki, past members Michael Hess and Petr Novak, and Journal of The Electrochemical Society (JES) published author Claire Villevieille.

(PS: Check out their past paper, “Surface/Interface Study on Full xLi₂MnO₃·(1 − x)LiMO₂ (M = Ni, Mn, Co)/Graphite Cells.”)

This from Paul Scherrer Institute:

The reason: the step-like concentration gradient gives way to a gentle, ramp-like progression of the lithium concentration. This is because, at higher voltages, the lithium ions involved in the charging process are distributed across the volume of the electrode particles for brief moments as opposed to being herded together in a thin layer boundary. As a result, the lithium can be set in motion more easily during charging, without the need for more energy to be added to negotiate the layer boundary.

Earlier this year, we looked at the Israeli start-up company StoreDot’s innovative research in battery technology that could allow a smartphone battery to charge in just 30 seconds.

Now, the same company is taking that same technology and applying it to electric vehicles.

The company is claiming to have tweaked their technology to fully charge an electric car in just five minutes.

According to StoreDot, an array of 7,000 cells could enable electric vehicles to travel up to 300 mile on just a five minute charge.

This from Ecomento:

StoreDot believes it can speed up charging by creating a new variant of the industry-standard lithium-ion chemistry. It uses nanotechnology to make new organic materials that researchers claim have lower resistance than the materials used in current lithium-ion cells. That means electricity can flow through the battery more easily.
