Dipping and Coating for Better Batteries

Dean Sigler Electric Powerplants, Sustainable Aviation 1 Comment

Could dipping electrodes in a secret sauce improve supercapacitor and battery endurance and power?  Could coating cell internals be the flavor of the month?  These recipes for better batteries may improve things at a better than normal rate, if California researchers have anything to say about it. Working with his compatriot Dr. Jaephil Cho in South Korean, Dr. Cui of Stanford University has been a leader in developing improved battery technology, even developing a painted paper battery.  In an appearance at the 2009 Electric Aircraft Symposium, Cui explained a basic truth of battery development – that improvements generally created about eight percent greater power or endurance in cells every year, leading to a doubling of battery capabilities every seven and one-half …
