Nanovacuums enable better batteries, memories

Abstract:
Researchers at the University of Illinois at Urbana-Champaign claim the vacuum tube could be basis of a high energy density battery, or a non-volatile memory. In theory arrays of nanometer-scale vacuum tubes should be able to achieve 3x the energy density of Li-ion batteries.

The researchers—Alfred Hubler and Onyeama Osuagwu—have prepared a paper entitled Digital quantum batteries: energy and information storage in nanovacuum tube arrays. However, the work is theoretical and it remains to be seen whether the technology can live up to its theoretical potential.
