Stanford researchers seek ‘Holy Grail’ in battery design – triple density and lower cost four-fold

"In practical terms, if we can triple the energy density and simultaneously decrease the cost four-fold, that would be very exciting," Chu said. "We would have a cell phone with triple the battery life and an electric vehicle with a 300-mile range that cost $25,000 – and with better performance than an internal combustion engine car getting 40 mpg."
