Utah might just be the first country to take the first step in innovating charging batteries and make them faster. The country claims that its new technology allows people to charge their smartphones and other gadgets, as well as electric vehicles, up to 80% in less than ten minutes.
Right now, Utah’s new technology could be one of the best charging innovations. The country’s efforts could allow it to compete with EV giants, such as Tesla, and other big manufacturers, including Apple, Samsung, OnePlus, and more. Batteries have come a long way over the years, but there are still improvements that can be made, especially when it comes to how long it takes to charge them.
Dr. Tao Gao, an Assistant Professor of Chemical Engineering at the University of Utah, wrote a research paper opening the door to creating a battery that can be recharged quicker than existing ones. He said that “my research is the first step towards that goal because to achieve that goal we need to understand the physical limitations of that.”
Utah’s new charging tech
The battery expert from Utah explained that the charging ability of a lithium-ion battery is affected by the so-called lithium plating. This is a side reaction that happens when lithium-ions are put into graphite particles too fast. Gao compares the operation of a lithium-ion battery to a ping pong ball being batted back and forth on a table.
On the other hand, Utah’s expert compared the operation of a lithium-ion battery to a ping pong ball being batted back and forth on a table. The ball, or lithium-ion, travels from the positive electrode to the negative electrode during the charging process. The charging rate is similar to how fast the ball travels.
He also explained that their latest innovation found out that Lithium plating happens when the lithium-ion moves too fast and the graphite particles in the battery fail to catch it. Limitations of charging lithium-ion batteries faster include the increased danger of catching fire or exploding and limiting how long they last in the long run.
The ultimate goal of the country’s innovation is to provide a way for batteries to charge faster whether that’s in smartphones, laptops, and electric vehicles (EVs) like Teslas, so you can spend less time waiting to charge and more time on the go. As of the moment, it takes about 40 minutes to charge a Tesla Model 3 to 80% battery from close to empty. This means that the country’s latest technology could beat Elon Musk’s giant EV company when it comes to battery charging.
Gao added that the innovation could also allow the country to have a new battery charging technology that has the same charging time as gasoline stations. He added that they are “aiming to basically reduce the battery’s charging time to within 10 minutes.”
