A new open access paper published in the Journal of The Electrochemical Society entitled, “Lithium-Ion Cathode/Coating Pairs for Transition Metal Containment,” finds a new cathode coating for li-ion batteries that could extend the technology’s lifespan.

According to Green Car Congress, the dissolution of transition metals is a major contributor to a li-ion battery’s expedited aging and degradation. However, this new study published in JES by ECS members David Snydacker, Muratahan Aykol, Scott Kirklin, and Christopher Wolverton from Northwestern University makes the case for a new, promising candidate that can act as a stable coating and limit the dissolution of transition metals into the lion electrolyte. That candidate is Li₃PO₄.

This from “Lithium-Ion Cathode/Coating Pairs for Transition Metal Containment”:

There are several distinct categories of strategies for limiting TM dissolution from the cathode. Electrolytes can be tailored to reduce reactivity with the cathode. Cathode materials can be doped to control the oxidation states of transition metals. This doping can be applied to the entire cathode particle or just near the surface. Cathode materials can also be covered with surface coatings to limit TM dissolution. Surface coatings can perform a variety of functions for different cathode materials. In this work, we evaluate the ability of coating materials to contain TMs in the cathode and thereby prevent TM dissolution into the electrolyte.

An interdisciplinary team of researchers based out of the University of Illinois at Chicago believes they may have just changed the game in solar cell technology.

According to the recently published study, the team promises a solar cell that not only harvests energy, but cheaply and efficiently transforms atmospheric carbon dioxide into useable hydrocarbon fuel – all with a little help from the sun.

The new development differs from typical solar technology, where the cells convert sunlight into energy to be stored in batteries or other energy storage devices. Instead, the new research uses solar cells in a way similar to organic photosynthesis, just amplified.

By capturing dangerous greenhouse gases and converting them into alternative, clean fuels, the researchers believe a farm full of these “artificial leaf” solar cells could begin to significantly reduce the amount of carbon dioxide in the environment and help shift the energy landscape toward more green alternatives.

“The new solar cell is not photovoltaic—it’s photosynthetic,” says Amin Salehi-Khojin, senior author of the study. “Instead of producing energy in an unsustainable one-way route from fossil fuels to greenhouse gas, we can now reverse the process and recycle atmospheric carbon into fuel using sunlight.”

Enzyme-based sensors detect lactate levels in sweat

It may be clammy and inconvenient, but human sweat has at least one positive characteristic – it can give insight to what’s happening inside your body. A new study published in the ECS Journal of Solid State Science and Technology aims to take advantage of sweat’s trove of medical information through the development of a sustainable, wearable sensor to detect lactate levels in your perspiration.

“When the human body undergoes strenuous exercise, there’s a point at which aerobic muscle function becomes anaerobic muscle function,” says Jenny Ulyanova, CFD Research Corporation (CFDRC) researcher and co-author of the paper. “At that point, lactate is produce at a faster rate than it is being consumed. When that happens, knowing what those levels are can be an indicator of potentially problematic conditions like muscle fatigue, stress, and dehydration.”

Utilizing green technology

Using sweat to track changes in the body is not a new concept. While there have been many developments in recent years to sense changes in the concentrations of the components of sweat, no purely biological green technology has been used for these devices. The team of CFDRC researchers, in collaboration with the University of New Mexico, developed an enzyme-based sensor powered by a biofuel cell – providing a safe, renewable power source.

Biofuel cells have become a promising technology in the field of energy storage, but still face many issues related to short active lifetimes, low power densities, and low efficiency levels. However, they have several attractive points, including their ability to use renewable fuels like glucose and implement affordable, renewable catalysts.

New lithium-oxygen battery technology proposed by researchers from MIT, Argonne National Laboratory, and Peaking University, promises a scalable, cheap, and safe option in energy storage.

There is immense promise for lithium-oxygen batteries in such applications as electric cars and portable electronics. In fact, they are between five and 15 times more efficient than lithium-ion batteries in transportation applications due to their high energy output potential in proportion to their weight.

But there have been complications in developing and especially implementing these batteries in the marketplace. Primarily, they’ve been known to waste energy and degrade quickly.

But this new study, co-authored by ECS member and past IMLB chair Khalil Amine, states that the theoretical potential for lithium-oxygen batteries could be met while overcoming some of the biggest barriers prohibiting the technology.

Once of the primary focuses of the group was overcoming the mismatch in voltages that happens in charging and discharging the battery. Because the output voltage is more than 1.2 volts lower that that used to charge, there is typically a significant power loss.

“You waste 30 percent of the electrical energy as heat in charging,” says Ju Li, professor at MIT and co-author of the paper. “It can actually burn if you charge it too fast.”

Overcoming barriers in scholarly publishing

In 1995, Forbes published an article entitled, “The Internet’s first victim?” In the article, author John Hayes predicted the world of commercial, for-profit scholarly publishing would suffer under the thumb of the internet and begin the slow process of fizzling out for lack of ability to turn a profit.

Turns out he was wrong.

Commercial scientific publishing has adapted to the times, becoming a multi-billion dollar industry; a $25.2 billion industry to be exact.

The rise of the for-profits

According to CBC News, the top for-profit scientific publishers report profit margins of nearly 40 percent, making some of those margins even higher than that of companies like Apple and Google.

The divide between ECS publications and that of top commercial publishers has deep roots. In the early days of scientific publishing, most journals came out of nonprofit scientific societies like ECS. However, the digital age changed things. It did not stifle the commercial publisher as Hayes thought, instead it hurt the scientific societies. Because the cost to make the switch from print to digital was so high, many societies sold their journals to large, for-profit publishers.

The top five largest, for-profit, academic publishers now publish 53 percent of all scientific papers in natural and medical sciences, but ECS still remains as one of the last independent scientific society publishers, and is still committed to the initial vision of the journals: to disseminate scientific research to the broadest possible audience with the fewest barriers.
