Stanford breakthrough could triple battery life
Annoyed by how often your cellphone needs recharging? Stanford researchers say they've made a major step toward the "holy grail" of energy storage — a pure lithium battery. A team that includes former Energy secretary Steven Chu says it's building a lithium anode battery that might give electric vehicles a 300-mile driving range and triple a cellphone's juice. Stanford professor Yi Cui says it will likely take three to five years, though, to bring the product to market. Their work is partly of an intensifying push to build a better battery — not only for portable electronics but also for storing solar and wind power for times when the sun doesn't shine and the wind doesn't blow. Universities, start-ups and major companies are working with new materials, such as vanadium, or tweaking the lithium-ion battery that Sony introduced more than 20 years ago.
