FAQ
1.How is energy stored in supercapacitors cells?
Supercapacitors (SCs) are electrochemical energy storage devices
that store and release energy by reversible adsorption and
desorption of ions at the interfaces between electrode materials
and electrolytes.
2.Can you do OEM or ODM?
OEM and ODM are both acceptable. Please contact us for more
details.
3. Is it a super capacitor or battery?
It's a combination of super capacitor and battery, which combines
power density of super capacitors and energy density of batteries.
4. what services can we provide?

5.Can supercapacitors replace batteries?
Supercapacitors are superior to traditional capacitors due to their
ability to store and release energy; however, they haven't been
able to replace the function of conventional Lithium-Ion batteries.
