On the western china international economy & trade fair, I find a company, its name is daying juneng technology and development co,. ltd. it shows many kinds of Super capacitors. and the capacitor of super capacitors is higher than 2000F. This is a very large capacitor. but its voltage is a little low. I think that it will be used in the electric vehicle and hybrid & electronic vehicle more and more. and maybe it will be instead of the lead-acid battery someday.
what do you think about that? welcome you to show your mind!
