only made landlines obsolete for many, but [the lithium-ion battery] put cameras and the internet into the hands of millions.” That huge leap didn’t happen overnight. “It was the sum of many incremental steps forward, and decades of work,” says Crabtree,

, who coordinates battery research in dozens of U.S. labs.
Lithium-ion batteries have their limits, however, especially for use in the power grid and in electric vehicles. Fortunately, like their Energizer mascot,

, universities, tech companies and car manufacturers have explored hundreds of new battery technologies,

, reaching for an elusive and technically difficult goal: next-generation batteries that hold more energy, last longer and are cheaper, safer and easier to recharge.
A decade of incremental steps are beginning to pay off. In late 2017,

, scientists will introduce a handful of prototype batteries to be developed by manufacturers for potential commercialization. Some contain new ingredients — sulfur and magnesium — that help store energy more efficiently,

“These prototypes are proof-of-principle batteries,

Power struggle
Batteries operate like small chemical plants. Technically, a battery is a combination of two or more “electrochemical cells” in which energy
