Revolutionary 3D nanohybrid lithium-ion battery could allow for charging in just seconds
“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).
Putting those thousands of anodes and cathodes just 20 nanometers (billionths of a meter) apart allows for extremely fast charging** (in seconds or less) and also allows for holding more power for longer…”
