From Cornell Chronicle site: The world is a big place, but it’s gotten smaller with the advent of technologies that put people from across the globe in the palm of one’s hand. And as the world has shrunk, it has also demanded that things happen ever faster – including the time it takes to charge an electronic device.
A cross-campus collaboration led by Ulrich Wiesner, the Spencer T. Olin Professor of Engineering in the Department of Materials Science and Engineering, addresses this demand with a novel energy storage device architecture that has the potential for lightning-quick charges.
The group’s idea: Instead of having the batteries’ anode and cathode on either side of a nonconducting separator, intertwine the components in a self-assembling, 3D gyroidal structure, with thousands of nanoscale pores filled with the components necessary for energy storage and delivery...
