Fuel cells that react liquid sodium metal with air could be the power source required to give electric airplanes much longer ...

When the alkali metals are cut, they initially appear shiny grey but quickly become dull and white as they react with oxygen in the air. This is known as tarnishing. Sodium tarnishes more quickly ...

Many metals react with oxygen to form metal oxides. Potassium and sodium are soft metal which are easily cut exposing a shiny surface which changes to dull rapidly. The change from shiny to dull ...

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