Transformation of bulk alloys to oxide nanowires

Abstract

Alcohols remove lithium to make nanowires Many existing routes for making metal and metal oxide nanowires are complex, require harsh solvents, or are not easily scaled up. Lei et al. developed an extraction process to remove lithium from aluminum or magnesium alloys by using alcohol solvents. The resulting highly reactive Al or Mg atoms formed alkoxide nanowires, which could be converted into oxides by high-temperature treatment. The authors used this approach to produce Al 2 O 3 separators that enhanced the safety of lithium batteries. Science , this issue p. 267
