UCal Researchers develop nanowire battery that could last for decades
A Battery You Never Have To Change http://rgn.bz/eB7L

University of California, Irvine researchers have invented nanowire-based battery material that can be recharged hundreds of thousands of times, moving us closer to a battery that would never require replacement. The breakthrough work could lead to commercial batteries with greatly lengthened lifespans for computers, smartphones, appliances, cars and spacecraft.

Scientists have long sought to use nanowires in batteries. Thousands of times thinner than a human hair, they’re highly conductive and feature a large surface area for the storage and transfer of electrons. However, these filaments are extremely fragile and don’t hold up well to repeated discharging and recharging, or cycling. In a typical lithium-ion battery, they expand and grow brittle, which leads to cracking.

UCI chemist Reginald Penner and doctoral candidate Mya Le Thai (shown) have developed a nanowire-based technology that allows lithium-ion batteries to be recharged hundreds of thousands of times.
