Ultra capacitors

i read about ultra capacitors that store energy (or u can say charge ) in hybrid cars. my question is why are'nt these capacitors replacing lead acid batteries which pollute the environment on disposing . do these capacitors have any drawbacks? is there any difference between a capacitor and a battery?
thanx in advance........😁

    buddy,capacitor stores charge were as batteries generate charge using chemical reactions,the biggest disadvantage of capacitors is that it cant hold charge for long as far as i know no capacitors is still capable to hold charge as long as batteries life,and both require a source too,well fuel-cells are best option to replace batteries!!!
