There's a lot missing from that, obviously. Something may have gotten fouled up in translation--we suspect they meant "battery" rather than "capacitor"--but what it sounds like is that Nissan has come up with a new battery tech that uses tungsten oxide and vanadium oxide rather than carbon. The general bottleneck in reducing charging time isn't in the charger or the amount of power that can be pumped into batteries, but rather in the frailty of the batteries themselves--the cells can't handle too much current at once. So a new battery technology that can cope with a very high amount of energy without degradation could conceivable allow that kind of super-fast charging.
