Fuel cells powered with the metal could provide a new source of electric power that's far more energy-dense than lithium-ion ...

Engineers developed a fuel cell that offers more than three times as much energy per pound compared to lithium-ion batteries. Powered by a reaction between sodium metal and air, the device could be ...

It’s a very different approach to those currently in development, but could theoretically offer three times as much power for ...

Batteries are nearing their limits in terms of how much power they can store for a given weight. That's a serious obstacle ...

Researchers at the Massachusetts Institute of Technology (MIT) have developed a sodium-air fuel cell that could power future ...
