DOE seeks batteries with four times the juice

If lithium-ion batteries are “miraculous,” as one science writer called them, the Energy Department is looking to fund a quadruple miracle. The department’s Advanced Research Projects Agency-Energy office is giving six teams up to $15 million to produce prototypes of manufacturable next-generation energy storage within two years. “We want to develop a system, a battery system or an energy system, that has four times the energy density of lithium ion batteries th
