Silicon anodes had been dismissed because the silicon tended to crack and become unusable as it swelled by 400% with lithium during charging.
Commercialization was originally expected to occur in 2012, but was later deferred to 2015.
Cui's company, Amprius, shipped a related device with silicon and other materials in 2013.
In September 2010, the Stanford team demonstrated 250 charge cycles at above 80 percent of initial storage capacity. Use in electric vehicles requires thousands of cycles.

Famous quotes containing the word design:
“If I knew for a certainty that a man was coming to my house with the conscious design of doing me good, I should run for my life ... for fear that I should get some of his good done to me,—some of its virus mingled with my blood.”
—Henry David Thoreau (1817–1862)
“Joe ... you remember I said you wouldn’t be cheated?... Nobody is really. Eventually all things work out. There’s a design in everything.”
—Sidney Buchman (1902–1975)
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (1613–1680)
