Illinois Researchers Create 3D Battery Electrode That Could Make EVs Charge In Minutes

Ovidiu Sandru — Mon, 21 Mar 2011 16:13:54 +0000

The big problem with nowadays' batteries is that they charge and discharge slowly. They can be made to charge and discharge faster at the price of their shortened lifetime, but that's not a solution at all. Supercapacitors may offer fast charge/discharge rates, but their capacity is just not very high. A hybrid of these two would be perfect.
