Self-assembling 3D battery would charge in seconds

A cross-campus collaboration led by Ulrich Wiesner, professor of engineering in the at Cornell University, 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 elements necessary for energy storage and delivery.
