Someday, electric vehicles could go distances fit for road trips across Texas.
Researchers at the University of Texas at Austin, who have previously made strides in the lithium-ion battery industry, have developed a new electrode for such batteries that could draw greater power and allow faster charging.
So far, the research has looked at just a single type of battery electrode and is in its early stages. But it offers exciting potential as some buyers consider driving range an important factor when making the switch to an EV or picking one.
Tesla’s Model Y being produced out of Giga Texas, for example, offers an estimated 330-mile range, which is lower than what many have become accustomed to in gas-powered vehicles.
So UT professor Guihua Yu, along with other researchers, had their findings on battery electrodes published in the Proceedings of the National Academy of Sciences.
“The unprecedented growth of electric vehicles during the past decade has played an indispensable role in paving the way for a carbon-neutral future,” the researchers write.
That’s why it’s key to address a hitch with next-generation batteries, where restacking material can cause “significant bottlenecks” in charge transport, Yu says. Consequently, it can be difficult to achieve high energy and fast charging.
To tackle the sluggish reactions of electrodes, the team used thin two-dimensional materials as the building blocks and stacked them to create thickness. Then, they used a magnetic field to manipulate their orientations and put the materials in vertical alignment. In doing so, researchers essentially made a fast lane for ions to travel through the electrode.
They compared their results to a commercial electrode and a horizontally arranged one for experimental control purposes. In that comparison, they recharged the vertical thick electrode to 50% energy level in 30 minutes. The horizontal electrode took 2 hours and 30 minutes.
Zhengyu Ju, a graduate student in Yu’s research group who is leading this project, said the team’s electrode shows superior electrochemical performance.
In part, that’s “thanks to the unique architecture we designed,” Ju said. It ultimately allowed for high mechanical strength, high electrical conductivity and facilitated lithium-ion transport.
Going forward, the team aims to generalize their methodology of vertically organized electrode layers to apply it to different types of electrodes using other materials. They imagine if this technique becomes more widely adopted in industry, it may create future fast-charging, high-energy batteries to power EVs.
