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

Hydrogen fuel cells, which power some electric cars, pack far more energy per weight than lithium-ion batteries. The devices ...

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 ...

MIT engineers developed a fuel cell that offers more than three times as much energy per pound compared to lithium-ion ...

Researchers at MIT have developed a low cost fuel cell that, in tests, has proved able to carry there times as much energy as ...

The atom with eight protons in its nucleus (atomic number 8) is oxygen. Each energy level holds ... A small piece of sodium metal is placed in water. The sodium reacts with the water and gets very hot ...

Researchers at MIT have revealed a new energy storage solution that surpasses today’s lithium-ion batteries in energy density ...

Batteries designed to run on oxygen from inside the body could last months or years before needing to be recharged or replaced, and might one day power everything from pacemakers to brain implants.

Gold has been known for its compatibility with living systems, and sodium is an essential and ubiquitous element in the human body. The electrodes undergo chemical reactions with oxygen in the ...
