Have you ever wished you could increase your cellphone battery life? Well, that technology may very well already be here.

Researchers from AMBER, the Science Foundation Ireland Research Centre for Advanced Materials and BioEngineering, at Trinity College Dublin, have announced the development of a new material which offers the potential to improve battery life in everyday electronics, like smartphones, according to Irish Tech News.

The discovery could mean that the average phone battery life, roughly 10 hours of talk time, could increase to 30-40 hours.

MXenes, an ink-based nanomaterial, not only significantly improves battery life, but it also offers its batteries the flexibility to become smaller in size, without losing performance. (more…)

Kang Xu on Fluorinating Interphases

Kang Xu, lead author.

“What is the most ideal [solid-electrolyte interphase] SEI or interphase that would enable the next generation of the battery chemistries?”

It was a question that had been lingering in the minds of Kang Xu, fellow of US Army Research Laboratory and team leader; Chunsheng Wang, University of Maryland chemical and biomolecular engineering department professor, as well as one of the most cited researchers of 2018; and Ying Shirley Meng, University of California, San Diego nanoengineering professor, fellow of The Electrochemical Society, and associate director of the International Battery Association.

Together, the trio set out to pursue this question, resulting in the publication of their paper “Perspective—Fluorinating Interphases.” (more…)

It’s winter. And with that comes heavy coats, icy winds, and occasionally, below freezing temperatures: conditions not favorable for batteries.

Car batteries

Temperature extremes, in general, are not favorable to batteries. According to Lifewire, lead-acid batteries drop in capacity by about 20 percent in normal to freezing weather, and down to about 50 percent in temperatures that reach about -22 degrees Fahrenheit.

As a result, you may find your car battery giving out on any given winter morning. This is due to reduced capacity and increased draw from starter motors and accessories. This is because starter motors require a tremendous amount of amperage to get going: knocking out the capacity of even the newest batteries. (more…)

Let’s face it. Anyone can benefit from a boost in their cell phone’s battery life, with the use of social media apps like Facebook, Instagram, Twitter, and the daily connectedness of email, texting, FaceTime, and selfies, it’s a surprise if our cell phone batteries last a day—which most often they don’t. Cut to, Apple’s newly released smart battery case that extends the life of their latest iPhones: the XS and XR. (more…)

Magnesium Batteries: New Discovery

A new version of high-energy magnesium batteries has been discovered by researchers from the University of Houston and the Toyota Research Institute of America, according to Phys.org. The battery operates with limited electrolytes while using an organic electrode, allowing it to store and discharge much more energy than earlier magnesium batteries.

Yan Yao, an ECS member, UH Student Chapter faculty advisor, and an associate professor of electrical and computer engineering at the UH, said the researchers identified chloride—in the commonly used electrolyte—as a contributor to magnesium batteries’ sluggish performance.

Yao, a principal investigator with the Texas Center for Superconductivity at UH, used the chloride-free electrolyte to test organic quinone polymer cathodes with a magnesium metal anode; the battery remaining stable through 2,500 cycles.

Magnesium batteries are particularly exciting as magnesium itself offers far more natural advantages over lithium. (more…)

Holiday Warning: Deadly Batteries

With the holidays fast approaching, you may find yourself purchasing toys and gifts for some little ones. As you do, it’s important to keep some safety tips in mind. The National Capital Poison Center recently reported an increasing number of fatal button batteries ingestions over the years.

These coin-sized batteries have the potential to cause severe esophageal or airway burns when stuck in the esophagus, even after no initial signs of irritation directly after ingestion. Batteries stuck, including in the nose and ears, for over 2 hours can cause burns and serious complications.

Most commonly nickel-sized button batteries are the most hazardous as their size can allow them to become lodged in the throat and burn faster as a result.

However, there are measures that gift-givers and parents can take.

Honda’s Battery Breakthrough

The search for the next level, new, and improved electric vehicle battery is an ongoing one. And it’s one Honda may have found. According to The Drive, the Japanese automaker claims to have developed a new battery chemistry called fluoride-ion that could outperform current lithium-ion batteries.

Honda says fluoride-ion batteries offer 10 times greater energy density, meaning more storage and range for electric vehicles, thanks to the low atomic weight of fluorine that makes fluoride-ion batteries’ increased performance possible. (more…)

Bentley Gives EVs the Red Light

High-end, high-class, and high-cost are all words synonymous with the word Bentley. The luxury car CEO Adrian Hallmark says he plans to keep it that way, and for that reason, he’s giving the inclusion of electric vehicles to the Bentley family the red light—for now.

Hallmark says battery technology has not evolved to the point where it would be possible to develop an ultraluxury electric vehicles, according to Tires and Parts. (more…)

Haodong Liu, recipient of the Battery Division Postdoctoral Associate Research Award Sponsored by MTI Corporation and the Jiang Family Foundation

Haodong Liu, a postdoc research fellow at UC San Diego, is the award winner of the Battery Division Postdoctoral Associate Research Award Sponsored by MTI Corporation and the Jiang Family Foundation for his work on “Stable Li Metal Anode through Designed Solution Chemistry and Electrode Architecture.” Liu was presented with the award at AiMES 2018 in Cancun, Mexico.

Liu says being recognized for his work has been an exciting experience, bringing recognition to his name and research within the battery field. However, it has also meant something more to him in particular.

“Since my citizenship is in China, and a lot of the scholarships here are only for the US citizens, this is a good chance for international postdocs to get awards and be recognized,” explains Liu. “ECS only cares about the quality of the work you’re doing instead of what’s your citizenship status. That’s why I really appreciate ECS.” (more…)

The Current State of Battery Research

By: Marca Doeff, ECS Battery Division Chair

Marca Doeff, a staff scientist in the Energy Storage and Distributed Resources Division at Lawrence Berkeley National Laboratory and chair of the ECS Battery Division, discusses the future of batteries. Doeff covers advancements and developments, notable contributors and leaders, corporate sponsors and supporters, upcoming meetings and awards, all within the battery field.

What are a few current areas of battery research the division is focusing on?
Anything having to do with lithium-ion batteries, since they are turning out to be the real workhorses of the battery world. While the chemistry is fairly mature at this point, there is still a lot of work going on in silicon anodes, trying to find better cathode materials, and improving electrolytes.
