Cornell University engineers have designed a revolutionary 3D lithium-ion battery that could be charged in just seconds.

In a conventional battery, the battery’s anode and cathode (the two sides of a battery connection) are stacked in separate columns (the black and red columns in the left illustration above). For the new design, the engineers instead used thousands of nanoscale (ultra-tiny) anodes and cathodes (shown in the illustration on the right above).
