Forever-lasting Batteries?
A few years back I came across this discovery:
The study was conducted in coordination with the Nanostructures for Electrical Energy Storage Energy Frontier Research Center at the University of Maryland, with funding from the Basic Energy Sciences division of the U.S. Department of Energy.
By coating the gold nanowires in a thin gel, the filaments of the capacitor retain their properties under hundreds of thousands of charges.
Batteries have fascinated humans for a long time, including the Mystery of the Baghdad Batteries:
As well as the Oxford Electric Bell:
With so much history, it’s probably only a matter of time until we indeed find “forever-lasting” batteries to power our lives.
