A battery with almost 100% efficiency is currently impossible… but only because today’s technology is way too big, say two European theoretical physicists. Robert Alicki, of the University of Gdansk in Poland, and Mark Fannes, of the University of Leuven in Belgium, are thinking very small indeed, by defining a battery that stores and releases energy using quantum mechanics, operating on a subatomic scale. The technology that would exploit their model, reported in Extreme Tech
, may be decades away.
But it is claimed such quantum batteries might power the tiniest of devices and when used en mass, provide power storage that is much more efficient than current lithium-ion batteries.
