New nanomaterial promises batteries that charge in seconds

Despite often annoying us with shorter-than-ideal lifespans and the occasional explosion, modern rechargeable batteries are actually quite remarkable, especially when you consider the power they're able to hold in very small footprints. That said, they could always be better, and while capacity is always a hot topic for those building the batteries of tomorrow, researchers at Drexel's College of Engineering believe they've discovered a way to make modern batteries a whole lot better by reducing ...
