A University of Texas at Dallas researcher has made a discovery that could open the door to cellphone and car batteries that last five times longer than current ones.
Dr. Kyeongjae Cho, professor of materials science and engineering in the Erik Jonsson School of Engineering and Computer Science, has discovered new catalyst materials for lithium-air batteries that jumpstart efforts at expanding battery capacity. The research was published in Nature Energy.
"There's huge promise in lithium-air batteries. However, despite the aggressive research being done by groups all over the world, those promises are not being delivered in real life," Cho said. "So this is very exciting progress. (UT Dallas graduate student) Yongping Zheng and our collaboration team have demonstrated that this problem can be solved. Hopefully, this discovery will revitalize research in this area and create momentum for further development."
Lithium-air (or lithium-oxygen) batteries "breathe" oxygen from the air to power the chemical reactions that release electricity, rather than storing an oxidizer internally like lithium-ion batteries do. Because of this, lithium-air batteries boast an energy density comparable to gasoline—with theoretical energy densities as much as 10 times that of current lithium-ion batteries, giving them tremendous potential for storage of renewable energy, particularly in applications such as mobile devices and electric cars.
For example, at one-fifth the cost and weight of those presently on the market, a lithium-air battery would allow an electric car to drive 400 miles on a single charge and a mobile phone to last a week without recharging.
Practical attempts to increase lithium-air battery capacity so far have not yielded great results, Cho said, despite efforts from major corporations and universities. Until now, these attempts have resulted in low efficiency and poor rate performance, instability and unwanted chemical reactions.
Cho and Zheng have introduced new research that focuses on the electrolyte catalysts inside the battery, which, when combined with oxygen, create chemical reactions that create battery capacity. They said soluble-type catalysts possess significant advantages over conventional solid catalysts, generally exhibiting much higher efficiency. In particular, they found that only certain organic materials can be utilized as a soluble catalyst.
Based on that background, Cho and Zheng have collaborated with researchers at Seoul National University to create a new catalyst for the lithium-air battery called dimethylphenazine, which possesses higher stability and increased voltage efficiency.
"The catalyst should enable the lithium-air battery to become a more practical energy storage solution," Zheng said.
According to Cho, his catalyst research should open the door to additional advances in technology. But he said it could take five to 10 years before the research translates into new batteries that can be used in consumer devices and electric vehicles.
Cho said he has been providing research updates to car manufacturers and telecommunications companies, and said there has been interest in his studies.
"Automobile and mobile device batteries are facing serious challenges because they need higher capacity," he said.
"This is a major step," Cho said. "Hopefully it will revitalize the interest in lithium-air battery research, creating momentum that can make this practical, rather than just an academic research study."

Two words...space probes. Batteries aboard still working how many YEARS after launch? Kinda far out to be solar charged. If science can make batteries like that the only reason we don’t have them for daily use is $$$! Big money industry selling expensive batteries for cell phones, comps etc. Long lasting anything kills the big disposables market.
Planned Obsolescence was the conspiracy which was instigated by a cartel in 1920 (The Light Bulb Conspiracy (documentary)).
Actually-—the elite sodomites have been planning the destruction of our habitat and enslavement and elimination of billions (for 200 years). Geo-engineering (destruction of the earth) and creating bio-engineered pathogens to release on the masses (or make mandatory vaccinations with all their viruses and aluminum-—to enslave and destroy autonomy (health)).
The AI movement is ALL about human obsolescence. (They wont need the boots in the army with drones, driverless cars-—cashless society gives complete control to the super psychotic sodomites who are feverishly trying to get total control of EVERYTHING.
They had the ability to make a light bulbs last over 100 years a hundred years ago, but they intentionally made the filament defective, so they could pollute and destroy the environment for wealth and control over the masses.
All marketing of ideas-—control the proper perceptions of the masses-—useful idiots (create a dog and pony “show”), so the elites can become masters and control the World and we are all distracted with gadgets and cr*- as the elites control the minds of our children—seduce them to the dark side (paganism/slavery).
You only “hear” what the elites want you to hear-—to keep us from Truth (God) Reality. (as they rape the earth and kill and enslave us). They stole Tesla’s papers in the 40s-—and have known how to produce “lasting” EVERYTHING-—but then people would not have to spend their crumbs on their products and might have time to raise their own children and control their own time. (Be free). Tesla wanted mankind to flourish, his ideas used for “good” of mankind—but the elites have different ideas and it “freedom” for the masses isn’t one of them.
Tesla’s father was an orthodox priest and his mother’s father was an orthodox priest. Without the Christian Worldview, there would have been no Tesla, no Age of Reason, no Modern Science. He was the most brilliant man of all history, other than Christ. That is why it is ONLY Christian Worldview which is being eliminated off of the face of the earth—the only worldivew which created Free Will, Individiualism-—which is inconsistent with slavers.
It seems that there is another “battery breakthrough” story promising massively enhanced capacity about every two months. If all of those stories were true by this point an AA battery would last about 100 years in continuous use. So, ever going to build it?
The long range probes are nuclear powered.
The Energizer bunnies will unionize, their employers will bribe congress to ban this technology.
dimethylphenazine appears to be nasty stuff.
I would guess that if you moved the batteries to a high current consumption device like a moving toy they would die immediately — but don’t do that it would be mean lol
I’ll believe it when they’re selling it to me. Forever battery rumors have been around so long they made fun of them on Barney Miller.
Nuclear batteries have certain logistical limitations that make them rather impractical for cellphone usage.
That’s because you plugged it on. :p
on = in.
“Open the door” is their code for this is all hype and will never make it to market.
But the batteries will still not be included. ;-)
aside from really frying one's brain
“dimethylphenazine appears to be nasty stuff.”
I think even the toxic name would give you cancer!
Lithium batteries are pretty flammable. Hope they do some tests on this new stuff to make sure it doesn’t make them worse. Would be a shame if we invented new match head batteries. ;-)
I’m still waiting for that 100 mpg carburetor I read about 50 years ago.
Space probes usually have nuclear batteries. They produce electricity through the decay of a radioisotope :
