Example Sentences

The study, published in Biochar X, reports that the catalyst reaches a low overpotential of 250 mV at 10 mA cm² and remains highly stable for more than 50 hours when operating at elevated current density.

From Science Daily

Higher current density capability could also enable new applications in automotive and specialty industrial lighting, while faster switching speeds could find applications in visible-light communication technologies and VR glasses.

From Science Daily

The paper battery achieved an open circuit voltage of 1.8 volts, a 1.0 volt current density of 100 mA/cm², and a maximum output of 103 milliwatts/cm².

From Science Daily

The new study shows indium has two crucial characteristics as a battery anode: an extremely low migration energy barrier, which sets the rate at which ions diffuse in the solid state; and a modest exchange current density, which is related to the rate at which ions are reduced in the anode.

From Science Daily

These coated particles create a homogenous surface across which the current density is evenly distributed, preventing the growth of dendrites.
