Researchers at Cornell University propose a three-dimensional architecture for batteries, where instead of having the batteries’ anode and cathode on either side of a nonconducting separator, intertwine the components. For their proof of concept architecture, they used gyroidal thin films of carbon as anode featuring thousands of periodic pores coated with electronically insulating but ion-conducting separator. They used sulfur as anode backfilling it with an electronically conducting polymer poly[3,4-ethylenedioxythiophene] (PEDOT). According to the researchers, due to the nanoscale dimensions of the battery’s elements it has the potential for very fast charging… read more. TECHNICAL ARTICLE
