Lithium cells outperform Nickel Cadmium and Nickel Metal Hydride in almost every way. But they also need a little bit more babysitting to get the most out of them. That comes in the form of ...

Just as lithium-ion batteries have made nickel-cadmium cells boring and old hat, gallium nitride semiconductors are making silicon parts look unimpressive by comparison. [Brian Dipert] looked at ...

It uses a nickel and cadmium plate and potassium hydroxide as the electrolyte. Originally invented in Sweden in 1899, it became popular in the 1950s after a sealed version was developed.

The nickel-cadmium battery was invented by engineer ... some nationally uniform specifications for the size of battery cells, ...

Since then, the cells have shown remarkable stability ... unlike the cadmium contained in a nickel-cadmium (Ni-Cd) battery. The cadmium within the solar module is, therefore, no threat to the ...

Developed by the University of Toledo, the cell achived the highest efficiency ever reported for flexible cadmium telluride solar cells to date. The device reached an open-circuit voltage of 861 ...
