The latest advancement in capacitor technology offers a 19-fold increase in energy storage, potentially revolutionizing power sources for EVs and devices.

Charge (solid lines) and discharge (dashed lines) curves at different fixed current densities of 0.5, 2, 4 and 7 mA cm-2 for (a) A-TNO and (b) V-TNO electrodes are shown.

This capacitor is capable of high current densities and high-capacity charging and discharging at temperatures of 200-300°C, creating the world's first bulk-type all-solid-state capacitors.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Supercapacitors are definitely not the same as batteries, we all know that. They tend to have a very low operating voltage, and due to their operating principle of storing charge on parallel plates… ...

VPCs also retain the advantages of supercapacitors, such as a faster charging and discharging speed than batteries, and the ability to operate in a wide temperature range from -25 to 85ºC.

The downside is that with a fixed duty cycle, the charge rate drops to nearly nothing when the capacitor hits about 2.15 V. My goal for testing was to charge it to 2 V, so this was acceptable for now.

A capacitor is able to discharge and charge faster than a battery because of this energy storage method also. The voltage output of a supercapacitor declines linearly as current flows.

But it can charge and discharge nearly as fast as a capacitor, being able to completely discharge in about 20 seconds. As an added bonus, it's flexible and works fine when you bend it.
