The Verge: Here are two things you probably don’t know:
One, a whole bunch of the top power tool brands — including DeWalt, Black & Decker, Craftsman, Porter-Cable and more — are all owned by the same company, Stanley Black & Decker. Those 20-volt lithium-ion battery cartridges you stick into your drill, circular saw and weed whacker are all pretty much the same thing.
Two, a tiny startup called Amionx has figured out how to make lithium-ion batteries that don’t explode when they’re crushed, shot, or stabbed.
