It’s a form of torture waiting for your cell phone battery to be fully charged. Wouldn’t it be great to plug in and within seconds, voila, you’re ready to go.
Drexel University researchers have have found a way to faster charging batteries by developing a new battery electrode design using a material called MXene. The key to this process is MXene’s chemical makeup, which optimizes the flow of electrodes through it. Electrodes are places where energy is stored for batteries. Batteries hold ions in ports called “redox active sites” to hold a charge, and the number of ports a battery contains is directly proportional to the amount of charge it can hold. The more ports there are, the more energy the battery can hold. Mikhael Levi, PhD, and Netanel Shpigel, research collaborators from Bar-Ilan University in Israel, helped the Drexel group maximize the number of the ports accessible to ions in MXene electrodes.
“In traditional batteries and supercapacitors, ions have a tortuous path toward charge storage ports, which not only slows down everything, but it also creates a situation where very few ions actually reach their destination at fast charging rates,” said Lukatskaya who conducted the research as part of the A.J. Drexel Nanomaterials Institute. “The ideal electrode architecture would be something like ions moving to the ports via multi-lane, high-speed ‘highways,’ instead of taking single-lane roads. The macroporous electrode design achieves this goal, which allows for rapid charging”.
Yuri Gogotsi, the lead researcher a materials science and engineering professor said “the end result might be a battery that takes mere “tens of milliseconds” to fully recharge instead of minutes or hours” Gogosti said “ MXene’s application in the real world could lead to better lap top and electric batteries.”
According to Gogosti, it’s at least three years away from making its way into mass-manufactured products. But that won’t stop the team from exploring new applications in the short term.
No waiting? I can’t wait!
