A small dye-sensitized betavoltaic cell has radiocarbon on both the cathode and anode, which increases its energy-conversion efficiency.

"We have a lot of other technologies we're trying to implement." General Motors hints at major tech innovation that could ...

Batteries typically contain a positively charged electrode called a cathode, and a corresponding negatively charged one called the anode. In between these two components is the electrolyte ...

Conventionally, batteries feature two electrodes — one positive (commonly called the cathode) and one negative (the anode). Each electrode is paired with a thin metal foil called a current collector ...
