A magnetic resonance imaging method for peering inside capacitors while they are charging and discharging is allowing researchers to scrutinize the ion dynamics that govern the operation and ...

Researchers believe they’ve discovered a new material structure that can improve the energy storage of capacitors. The structure allows for storage while improving the efficiency of ultrafast charging ...

We tend to focus on charge storage in terms of the batteries that power our electronic devices and, increasingly, our cars. But charge storage devices now make an appearance on scales ranging from ...

Capacitors are able to charge and discharge more quickly than batteries, and can do so hundreds of thousands of times. Batteries, on the other hand, are able to store more energy than capacitors.

Capacitors are energy storage devices, consisting of two electrodes and an electrolyte, that are capable of rapid charging and discharging because of charge adsorption and desorption properties at the ...

A research team at Washington University in St. Louis has developed a technology that can create a capacitor with 19 times higher energy density than commercially available capacitors. According to ...

A research group has successfully developed a high-capacity capacitor, an energy storage device -- using a solid electrolyte with high deformability -- that can operate at high temperatures. With this ...
