Stanford Breakthrough Might 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.
