You probably didn't think much about it, but somewhere a battery may have just saved your city from a blackout. These kinds of batteries are for preventing the entire electrical grid from collapsing. And it turns out, the batteries doing this job need to be fundamentally different from the ones we've been talking about for years. A German research institute has built a battery that responds faster than you can blink. It's made from cheap, abundant aluminum instead of lithium, and it doesn't use a flammable electrolyte. In real-world grid tests, it reacted instantaneously to smooth out power fluctuations that would have caused widespread blackouts. But can a battery designed for speed and power instead of range actually scale into the grid-stabilizing role we desperately need?
