Suppose that you need to test a 1.5V, AA-size alkaline battery. You can apply a short circuit and measure current, or you can measure open-circuit voltage, but neither method properly tests the ...

The internal resistance of a standard alkaline cell increases as the cell's life accumulates, whereas the cell's open-circuit voltage hardly changes. This increased resistance causes a sharp drop in ...

Radio-photovoltaic cells, as a kind of nuclear battery, have a high energy density but low energy conversion efficiency (ECE). Scientists in China have developed a high-efficiency RPVC using ...
