Battery Technology: Highly Charged
Today's site, from the journal, The Economist, offers an article from a recent
print edition of the publication, outlining a particularly striking advancement
in
battery development. Gentle Subscribers will find a summary of the current
research
being carried out at one of America's respected universities.
"A powerful experimental battery that can be recharged completely in minutes ...
Engineers have long dreamed of shortening the time it takes to recharge
batteries.
Currently, that can be hours. For applications like motor vehicles it really
needs
to be reduced to minutes. Now Paul Braun and his colleagues at the University of
Illinois, Urbana-Champaign, have succeeded in building prototype batteries
which do
just that." - from the website
The report, a complete version of the print edition, covers the salient points
made
by Dr. Braun and his team in the peer-reviewed science journal 'Nature
Nanotechnology'. Documenting the research thus far, the article notes the
direction
it has taken, with its use of nano materials to facilitate the dramatically
increased charge rate. Before jumping completely on this spectacular
battery-driven
bandwagon, the generally informed discussion in the comments section is worth a
perusal. An unexpected feature of the site is The Economist's "Learn More"
option,
activated whenever text is selected, and providing various references for
further
information from widely consulted sources, as well as the The Economist's own
archives.
Thanks to subscriber DFA for the suggestion.
