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 ...

Chemists have discovered the key reaction that takes place in sodium-air batteries that could pave the way for development of the so-called holy grail of electrochemical energy storage.

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 ...

Drop a chunk of sodium metal into water, and you'll see an incredibly violent reaction take place. But what's the quantum reason for it?

Sodium reacts with oxygen and water to produce NaOH, which liquefies and drips off the cathode. After the reactions consume the liquid sodium, you would simply swap out the fuel cell or its fuel ...

Liquid sodium metal fills the tube on one side, and air flows through the other, providing the oxygen for the electrochemical reaction at the center, which ends up gradually consuming the sodium fuel.

Chemists at the University of Waterloo have discovered the key reaction that takes place in sodium-air batteries that could pave the way for development of the so-called holy grail of ...

Metals can be used as fuels, just like oil, gas, or hydrogen, because they release energy through burning or electrochemical reactions. Light metals like ...

Liquid sodium metal fills the tube on one side, and air flows through the other, providing the oxygen for the electrochemical reaction at the center, which ends up gradually consuming the sodium fuel.

Chemists have described a key mediation pathway that explains why sodium-oxygen batteries are more energy efficient compared with their lithium-oxygen counterparts.
