Egg-cellent World-record Battery Performance Date: Sunday, February 10, 2013 @ 17:54:30 UTC Topic: Science
SLAC and Stanford scientists have set a world record for energy storage,
using a clever “yolk-shell” design to store five times more energy in
the sulfur cathode of a rechargeable lithium-ion battery than is
possible with today’s commercial technology. The cathode also maintained
a high level of performance after 1,000 charge/discharge cycles, paving
the way for new generations of lighter, longer-lasting batteries for
use in portable electronics and electric vehicles.
The research was led by Yi Cui, a Stanford associate professor of
materials science and engineering and a member of the Stanford Institute
for Materials and Energy Sciences, a SLAC/Stanford joint institute. The
team reported its results Jan. 8 in Nature Communications.
