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?
