There isn't much in electronics that's as simple as a capacitor, a pair of film electrodes with insulating layer between them. The present best ones have much less capacity than a battery. The advantage is they can be charged and discharged very quickly.
Seems there are possibly going to be some changes if this is right. A possible 100X capacity would give a capacitor 5x more storage capacity than the newest batteries. One in your mobile phone or laptop would charge in seconds. Large ones in cars could charge in little more time than it takes to fill a petrol tank.
That would be a game changer.

If any of them succeeds and gets their product to market it could revolutionise transport and modern rechargeable equipment.
