University of California doctoral student Mya Le Thai holds a nanowire device that has the potential to enable hundreds of thousands of recharges in a lithium-ion battery.\u00a0This new discovery could lead to vastly longer lifespans for batteries in laptop computers<\/a>, tablet PCs, smartphones, appliances, cars and spacecraft.<\/p>\n

\n<\/a>Researchers have pursued using nanowires in batteries for years because the filaments, thousands of times thinner than a human hair, are highly conductive and have a large surface area for the storage and transfer of electrons.<\/p>\n

The problem they have encountered, however, is that nanowires are also extremely fragile and don’t hold up well to repeated discharging and recharging, known as “cycling.” For example, in a typical lithium-ion battery, they expand and grow brittle, which leads to cracking.<\/p>\n
