Researchers at Drexel University School of Engineering claim they have created a new highly conductive two dimensional material they call MXene that will permit faster battery charging. Led by professor Yuri Gogotsi, the team says electrodes made from MXene will allow ordinary batteries to charge as fast as supercapacitors but with the energy storage potential of a conventional battery.
“This paper refutes the widely accepted dogma that chemical charge storage, used in batteries and pseudocapacitors, is always much slower than physical storage used in electrical double-layer capacitors, also known as supercapacitors,” Gogotsi says. “We demonstrate charging of thin MXene electrodes in tens of milliseconds. This is enabled by very high electronic conductivity of MXene. This paves the way to development of ultrafast energy storage devices than can be charged and discharged within seconds, but store much more energy than conventional supercapacitors.”
