Low temperature maintenance-free supercapacitor price

Can a supercapacitor remain flexible and energy storage functional at 50 °C?

Herein, a supercapacitor prototype that remained flexible and energy storage functional at −50 ℃ was demonstrated, thanks to a hierarchically-structured self-standing pristine polypyrrole membrane (PPy-N) that showed high flexibility and electrochemical performances at ultra-low temperature.

Do supercapacitors have a low-temperature flexibility?

To our best knowledge, the supercapacitors with a low-temperature flexibility, especially based on conducting polymers, have not been reported. The main reason is that most conductive electrode materials inevitably become brittle at reduced temperature, resulting in the disappearance of the original flexibility of the supercapacitors.

How are low-temperature resistant Supercapacitors made?

Currently, the overwhelming majority of low-temperature resistant supercapacitors reported are fabricated by using the carbon materials, including the activated carbon , carbon nanotube , and reduced graphene oxide (rGO) , , as the electrodes.

How long do Eaton supercapacitors last?

Eaton supercapacitors are maintenance-free with design lifetimes up to 20 years (supercapacitor lifetimes vary based on charge voltage and temperature). Operating temperatures range from -15°C to +70°C for the HS series and the low-temperature option ranges from -25°C to +60°C for the HSL series. What are hybrid supercapacitors?
