The world is no stranger to flexible batteries, but they've almost always had to be made in thin sheets — that doesn't amount to a long running time if you're powering anything more than a watch. LG Chem has developed a flexible lithium-ion battery that's not just better-suited to our bigger gadgets but could out-do previous bendable energy packs. Researchers found that coating copper wires with nickel-tin and coiling them briefly around a rod results in a hollow anode that behaves like a very strong spring; mating that anode with a lithium-ion cell leads to a battery that works even when it's twisted up in knots.
