What is an ultra capacitor? What is capacitance? Well....let me tell you!
First off, let's talk about capacitance, capacitance comes from two plates which do not touch and are separated by a non-conductor "dielectric". Between the plates you have a dielectric "insulator". The surface area of one of your plates determines how much charge can be stored in one of the plates. As the charge builds on one side of the plate it creates and electric field that points from one plate to the next. The positive charges that have been built become stored in the electric field which can then be bled out into a circuit later and discharged.
I found this cool article about a new company creating ultracaps here on http://pirateswithoutborders.com
Check out the video below for this company in Estonia cranking out ultracaps!
These guys have created a composite graphene material to use in there capacitors which must yield an incredibly large surface area to store charge. However.......The ultracapacitor will not replace batteries anytime soon as they cannot hold the same energy density as batteries.
The advantage of the ultracapacitors is their ability to quickly charge and discharge. This is a huge application in electric vehicles where the capacitors can be used for acceleration and taking the charge from regenerative braking. This saves the batteries in the electric vehicle extending the life of the batteries.
Let me know what you think about the Ultracapacitors in the comments, Upvote, Follow, Re-steem to all your peeps!
