North Carolina State University building Nanofiber anodes to make Better Battery (July 23, 2009) — Current batteries used in hybrid and electric vehicles are large, expensive and not entirely practical for those looking for high-power vehicles, or for people driving them on longer trips.

BatteryDr. Xiangwu Zhang, professor at North Carolina State University and his team are using a technique called electrospinning to combine lithium alloy and carbon into new composite nanofiber anodes, which have the ability to produce more energy while costing less and tolerating abuse better than existing batteries. The batteries are also lighter, producing more power in a smaller package – ideal for use in vehicles.

Nanofiber anodes can be easily produced in large numbers, which could help reduce the demand for imported petroleum, decrease emissions of air pollutants and greenhouse gases.
