Supercapacitor, Ultracapacitor, EDLC

Model Number

HC, EC series

Vina Technology in Korea researches & manufactures Hybrid supercapacitor used in Solar LED lights instead of batteries, such as solar road marker/stud, solar house number, solar traffic sign etc.



This is not a battery : Hybrid supercapacitors have twice more energy than existing supercapacitors(EDLC) and have much higher power density than batteries.



Hybrid capacitors are of tens of thousands of cycle life and tolerant to severe temperature(-25C to +70C) with no maintenance over 10 years.



Furthermore, Hy-caps have no toxic material like lead-acid/ Nicd batteries, whose concept should be perfectly matched with your environment-friendly policy.

As you know about RoHS regulation, EU market will limit light & electric products containing hazardous materials such as Cd(Nicd battery) and Pb(Lead battery) from July 1st, 2006.



For your reference, I've attached two ralated files. I would like you to review them & consider applying Hybrid supercaps to your solar products.



I believe Hy-cap will benefit you by resolving battery's problems like short life cycle, frequent replacemnet, temperature matter.



If you have any questions or need samples, please feel free to let us know.



Looking forward to your sincere reply.


Best Regards,
