Let me ask you a question. Do you like heavy, clunky cell phones whose batteries lose their charge quickly? Of course not. Nobody does. And that’s why manufacturers are constantly seeking battery designs that are more compact and powerful. In the old days, the best we could do was nickel-cadmium chemistries. You can still find them in ancient cordless phones built in the early 1990s. But then lithium-ion made its breakthrough, and the world has never looked back. Lithium has more uses than duct tape. You’ll find it in fireworks, airplanes, glass cookware, and medicine cabinets. It’s even a key… Read More
Let me ask you a question. Do you like heavy, clunky cell phones whose batteries lose their charge quickly? Of course not. Nobody does. And that’s why manufacturers are constantly seeking battery designs that are more compact and powerful. In the old days, the best we could do was nickel-cadmium chemistries. You can still find them in ancient cordless phones built in the early 1990s. But then lithium-ion made its breakthrough, and the world has never looked back. Lithium has more uses than duct tape. You’ll find it in fireworks, airplanes, glass cookware, and medicine cabinets. It’s even a key raw material for rocket fuel propellant and nuclear reactor coolant. But that’s not why I like it. These are just niche applications. The true utility comes from the fact that lithium is endowed with some curious properties. It is the lightest of all metals (it can actually float on water) and has twice the energy storage density of previous materials. That’s an ideal combination, which is why lithium is coveted by battery makers. Last quarter alone, approximately 307 million smartphones were produced worldwide (about 140,000 per hour), most of which were outfitted with lithium batteries. And it’s not just phones. Read More
