CeB 6 and tungsten are both thermionic sources with a filament referred to as a cathode, from which electrons are generated. The emission begins when the electrons are supplied with sufficient energy ...

Anode – Typically made of reactive materials like lithium or zinc, the anode undergoes oxidation, releasing electrons. Cathode – A material capable of accepting electrons, the cathode undergoes ...

Spurred by concerns over cost, safety, and sourcing of raw materials, researchers are on the hunt for alternatives to lithium-ion batteries. Now, scientists have developed a proof-of-concept, ...
