Plexiglass Gel Boosts Nanowire Battery Lifespan

Plexiglass Gel Boosts Nanowire Battery Lifespan

A new battery material based on nanowires that can be recharged hundreds of thousands of times, could lead to commercial batteries for smartphones, laptops, appliances, cars, and spacecraft that have greatly enhanced lifespans, researchers say. Scientists have long sought to create batteries using nanowires—strands only nanometers, or billionths of a meter, wide. Their tremendous surface area when compared with their volume makes them spectacular at storing and transferring electrical charge. “Nanowires enable battery technology with higher power; you're able to get more current out of a battery the same size as [today’s] batteries, and make batteries smaller and get the same performance out of them as [the ones that are commercially available],” says Reginald Penner, an electrochemist at the University of California, Irvine . The one drawback of nanowires has been their f...
