Researchers are working on a lithium air battery that will make electric vehicles as practical as gas-powered cars.
ReVolt Technologies is one of a handful of companies trying to develop metal air batteries as an alternative lithium ion batteries.
Researchers at Virginia Tech have developed a working sugar-powered fuel cell with energy density greater than that of current lithium-ion batteries.
Big Blue signs on partners for its Battery 500 Project to design an "air-breathing" lithium air battery that would create a leap in energy density.
At the Paris Air Show, AgustaWestland shows off an exotic single-person aircraft designed to investigate all-electric, no-hydraulic flight systems.
Two-hour test is the first step in returning the aircraft to service after battery fire and heat issues forced the FAA to ground the fleet.
The Dreamliner maker plans to wrap the lithium-ion batteries in an electrical insulator to prevent heat exchange and cut holes in the battery enclosure to allow moisture to drain.
If the company is indeed working on a watch-size device with the bells and whistles of a smartphone, battery life could prove a challenge.
An MIT chemistry professor suggests that Boeing switch from lithium-ion batteries to the heavier but safer nickel metal-hydride technology, a process that could take a year.
